Excel Speeding up & Optimization Tips by Hui

About Hui:
Hui (Ian Huitson) has been writing & contributing to Chandoo.org for more than 2 years. Many of you know him from Formula Forensics & Data table related articles on Chandoo.org. See about Hui page for more about him.

In no particular order:

  • Minimize the use of Volatile Functions
  • Organize your workbook layout and data methodically
  • Where possible use fixed values or Named formulas instead of lookups even if the values only change rarely, flag those for manual checking
  • Don’t Start equations with a + that actually adds 0.4% calculation time
  • Minimize use of the Data Table command to running summaries only at the end of a project
  • Review the logic of the model and all if’s or lookup choices for necessity or alternatives
  • Use negatives instead of multiple positives where appropriate in conjunction with If’s and Lookups
  • Learn about Conjunctive Truth Tables, they Rock for reporting
  • Array formulas can do the work of dozens of normal cells, but use cautiously
  • Use Named Formulas and UDF’s instead of multiple Helper Cells/Rows or Columns
  • Minimize of us Conditional Formatting
  • Minimize use of linked workbooks especially if over network drives
  • Take an advanced Excel course like the ExcelHero Academy
  • Minimize the use of Excel 2007

Excel Speeding up & Optimization Tips by Gregory

About George:
Gregory runs Excel Semipro, where he shares Excel tips & ideas. I asked him to contribute to the Speedy Spreadsheet Week. This is what he says,

Tips by George:

To speed up my worksheet files, I have one primary rule: do not use the OFFSET function, which is volatile and can slow things down considerably. In newer spreadsheets I use Tables and The imposing INDEX function to keep ranges automatically updated. In Excel 2003 I use an event-based approach, with named ranges, the worksheet deactivate module, and VBA to keep lists and ranges updated.

Excel Speeding up & Optimization Tips by Luke

About Luke:
Luke is one of the Excel Ninjas at Chandoo.org where he contributed more than 1000 posts. I asked Luke to share some optimization tips based on his vast experience of using Excel & helping others. This is what he suggests:

  1. In VB, whenever I see a line like Selection.something that’s usually an indicator that I’m using extra lines. Either I need to apply the method directly to the object instead of selecting it, or I need to use a With statement.
  2. With Event macros, don’t forget the all-important lines of Application.EnableEvents = False and Application.EnableEvents = True so that you don’t cause multiple events to be triggered.
  3. See a section of code that you’re repeating? Probably need to make this a separate Sub or Function that you can then reference from the main code.
  4. When building your formula page, think top-down. Cells near the top of worksheet should be referenced in formulas that are below, not vice-versa. XL likes to calculate left to right, top to bottom. Scattering cell references around makes it work harder.
  5. When using large amounts of data that you want to be charted, sometimes I’ll build a formula sheet within the workbook with data, and then just build another workbook that uses a data query (referencing the formula results) to generate the charts.
  6. This might be more along the lines of auditing a worksheet, but sometimes it’s hard to see how I’ve laid out my constants and formulas, and using a worksheet map helps bring things into focus (related: create a worksheet map)

Excel Speeding up & Optimization Tips by Narayan

About Narayan:
Narayan is one of the Excel Ninjas at Chandoo.org where he contributed more than 1000 posts. I asked Narayan to share some optimization tips based on his vast experience of using Excel & helping others. This is what he suggests:

Period-to-Date and Cumulative SUMs
There are two methods of doing period-to-date or cumulative SUMs. Suppose the numbers that you want to cumulatively SUM are in column A, and you want column B to contain the cumulative sum; you can do either of the following:
You can create a formula in column B such as =SUM($A$1:$A2) and drag it down as far as you need. The beginning cell of the SUM is anchored in A1, but because the finishing cell has a relative row reference, it automatically increases for each row.
You can create a formula such as =$A1 in cell B1 and =$B1+$A2 in B2 and drag it down as far as you need. This calculates the cumulative cell by adding this row’s number to the previous cumulative SUM.
For 1,000 rows, the first method makes Excel do about 500,000 calculations, but the second method makes Excel do only about 2,000 calculations.

Subtotals

Use the SUBTOTAL function to SUM filtered lists. The SUBTOTAL function is useful because, unlike SUM, it ignores the following:
Hidden rows that result from filtering a list. Starting in Excel 2003, you can also make SUBTOTAL ignore all hidden rows, not just filtered rows.
Other SUBTOTAL functions.

Using SUMPRODUCT to Multiply and Add Ranges and Arrays.
In cases like weighted average calculations, where you need to multiply a range of numbers by another range of numbers and sum the results, using the comma syntax for SUMPRODUCT can be 20 to 25 percent faster than an array-entered SUM.
{=SUM($D$2:$D$10301*$E$2:$E$10301)}
=SUMPRODUCT($D$2:$D$10301*$E$2:$E$10301)
=SUMPRODUCT($D$2:$D$10301,$E$2:$E$10301)

These three formulas all produce the same result, but the third formula, which uses the comma syntax for SUMPRODUCT, takes only about 77 percent of the time to calculate that the other two formulas need.

Dynamic Ranges

These are most often created using the OFFSET and COUNTA functions , as in the following :
=OFFSET(Sheet1!$A$1,0,0,COUNTA(Sheet1!$A:$A)-1,1)

Sometimes , when data is stored in the form of records , so that all columns have data to the same extent , there may be several dynamic ranges ; say we have ORDER_ID in column A , CUSTOMER_ID in column B , and the AMOUNT in column C. Thus there may be several dynamic ranges as follows :
=OFFSET(Sheet1!$A$1,0,0,COUNTA(Sheet1!$A:$A)-1,1)
=OFFSET(Sheet1!$B$1,0,0,COUNTA(Sheet1!$B:$B)-1,1)
=OFFSET(Sheet1!$C$1,0,0,COUNTA(Sheet1!$C:$C)-1,1)

These can be simplified to :
=OFFSET(Sheet1!$A$1,0,0,COUNTA(Sheet1!$A:$A)-1,1)
=OFFSET(Sheet1!$B$1,0,0,COUNTA(Sheet1!$A:$A)-1,1)
=OFFSET(Sheet1!$C$1,0,0,COUNTA(Sheet1!$A:$A)-1,1)

These can then be optimized by storing the COUNTA value in a cell , and using the cell reference within the OFFSET formula :
=OFFSET(Sheet1!$A$1,0,0,Sheet1!$F$1,1)
=OFFSET(Sheet1!$B$1,0,0, Sheet1!$F$1,1)
=OFFSET(Sheet1!$C$1,0,0, Sheet1!$F$1,1)

Where Sheet1!$F$1 contains the formula : =COUNTA(Sheet1!$A:$A)-1
For more, refer to MSDN.

Resetting the USED RANGE

Pressing CTRL END will take the cursor and place it on the cell which Excel thinks is the last used cell in the worksheet.
Suppose you do this , and the cursor lands on D27 ; now navigate to any cell which is as far away as you can imagine , say AA3456 ; enter any character , even a space will do ; then clear the cell contents by pressing the DEL key.
Pressing CTRL END will now take the cursor to AA3456.
To reset the USED RANGE , go to the Immediate Window of the VBA Project , and enter the following statement :
Application.ActiveSheet.UsedRange
Your used range should now be reset to its earlier value of D27 ; pressing CTRL END will now take the cursor to D27.
Refer to this Stackoverflow discussion for more.

Excel Speeding up & Optimization Tips by Jordan

About Jordan:
Jordan runs Option Explicit, an Excel VBA blog. He shared these tips with us,

  • When reading and writing to ranges, use .value2 (this is noticeable for large, iterative calculations)
  • Ensure that ALL spreadsheet errors are handled. The most common errors I see ignored are #Ref errors and #Div (for dividing by zero). Use Go To Special… to find these errors and either delete them or use IFERROR to handle them. In my opinion, Excel errors are one of the biggest contributing factors to slow spreadsheets.
  • When using INDEX, include the row or column number even if you don’t need it. For example, if I’m pulling data from only one column, I need only write =INDEX(A1:A10, 1) to pull the first item. However, =INDEX(A1:A10, 1, 1) appears to be a hair faster. Try it.
  • Cut down on Lookup functions. In many instances, the lookup table has already encoded information in the correct order. Instead of looking up, say, Stage 2, just use INDEX on the desired column and pull from row 2.

Thanks to Hui, George, Gregory, Luke, Narayan & Jordan

    My most often used variation of this is to remove blanks from a list.

    Suppose column A contains information but some of the rows are blank. I want to return a continuous list of information without the blanks so I do...

    Your original formula looks like this:
    =IFERROR(INDEX($B$1:$B$20,SMALL(IF($A$1:$A$20=$E$2,ROW($A$1:$A$20)),ROW()-2),1),"")

    I want to look for non-blanks and all my data is in column A so I change it to:
    =IFERROR(INDEX($A$1:$A$20,SMALL(IF($A$1:$A$20"",ROW($A$1:$A$20)),ROW()-2),1),"")

    Ctrl+Shift+Enter, fill down and ta-da! A nice continuous list of information without any blanks.

    • Desk Lamp says:

      =IFERROR(INDEX($A$1:$A$20,SMALL(IF($A$1:$A$20"",ROW($A$1:$A$20)),ROW()-2),1),"")

      The original post chopped out my 'does not equal' for some reason. This is how it should look

  2. Jeff Weir says:

    Great stuff. I laughed. I cried. I hurled.

    Personally I would use a PivotTable and Gordon Ramsay. But hey...as long as we cook the books, then each to their own, I'd say.

  3. Elias says:

    I won’t recommend the use of ROW()-2 because everything gets mess if you insert a row(s) before the row 2. The alternative would be ROWS(E$3:E3).

    Regards

    • Husain says:

      Hi Elias,
      I tried doing what you have suggested here.
      Ading any additional row messes up everything like you siad. But using the formula that you have suggested, shows only one value for the entire array. Would you please help me undersatand your method. I feel I may not be doing it correctly.
      Regards

  4. Denice says:

    Thank you Sohail. Great post. The comments are also very helpful.
    PS! Jamie Oliver was a great choice.

  5. Mando says:

    I've been using data with multiple occurrences for awhile now, and was glad to see the question I've been trying to ask and don't know how finally got answered. Now if I can be brave enough to use this, is another question.
    What I usually do is just add another column to the end of my data =IF((COUNTIF($B$2:B2,B2))=1,1,"") where B is my unique identifier and then just do multiple COUNTIFS with it.
    For multiple Occurrences and Criterias, I just add another column to Concatenate my unique identifier and the other criteria =$B2&" "&$C2, then add another column using the same =IF((COUNTIF($B$2:B2,B2))=1,1,"") but this time use the column where I placed the concatenated data.
    Any ideas how to lessen the number of columns I use without using any Arrays or VBA's?

    • Sohail Anwar says:

      Hi Mando,
      Are you pretty much asking for an alternative way to do this without VBA/Array Formulas? If so, I would recommend not doing that, Arrays make things a bit easier. The method you wrote looks like it will increase work, I'm always in search of efficiency in the long term 🙂

  6. XOR LX says:

    It's both illogical and unnecessary to use a construction for SMALL's (or LARGE's) k parameter which consists of the ROW function (either in its unqualified form, i.e. ROW(), or with a reference, e.g. ROW(A1)) +/- some constant.

    Not only is such a construction necessarily dependent upon the row number in which the user decides to place the initial formula in the series, but it is also susceptible to error upon row insertions within the sheet.

    ROWS (i.e. ROWS($1:1), or ROWS(A$1:A1) if you prefer) gives precisely the same results, though suffers from neither of these two drawbacks:

  8. Sohail Anwar says:

    @Elias and XOR LX, great point and while I use the construct you mentioned in other things, I never really gave it too much thought since I owuldn't readily insert rows in this sort of thing.

    I love the rule of ROW(A1) +/- constant being illogical! Any time I can eliminate something from my arsenal due to redundancy is good. Much appreciated and once again this sort of exchange is precisely why we love Chandoo 🙂

  9. Jonathan James says:

    Great post, love this way of retrieving lists of items. Will certainly be giving this a go.

  10. Mr J says:

    I like this technique a lot and *will* be using it. However how can it be done in 2D. E.g I have a 3 by four table (12 items) and each items is either an "Apple" or an "Orange". I want to get the row and column position of each occurrence of "Apple" and of "Orange"? How would I do this?

  11. XOR LX says:

    @Mr J

    When you say "row and column position", do you mean relative positions or absolute? For example, if your table was in A10:D12, and the first occurrence of "Orange" was in cell B11, would you want 11 (absolute) or 2 (relative) returned for the row position?

    Regards

  12. Shakil says:

    The master database contain name, designation, salary, passport no, expiry date, joining date, project no. camp name, floor no., flat no., room no., around 20 more column, and this is more than 500 staff member.

    i want to make report for the camp and i want use the employee ID to transfer their name, designation, flat no., and their room no only to other sheet using VBA code.

    Please help me.

    Thanks

    Great post, love this way of retrieving lists of items.

  14. BeEman says:

    This was a great post and I learned a lot. i am attempting to do exactly what this post was about with the exception of direction, i want to go across not down. is this possible?

  15. Skrattoune says:

    To summarize for those who will not take the time to go through the whole comments list (and who therefore will avoid some brain overload and save some grey cells), use at the end of your array formulas

    ROWS($1:1) instead of ROW()-2

    it additionally is more intuitive for understanding the formula:
    ROWS($1:1) => displays 1st result
    ROWS($1:3) => displays 3rd result
    ...

    Thanks all for this posts & comments

  16. Srinivasan says:

    Difficult to understand
    But I am sure it will be of immense use to me

  17. CJS says:

    Very useful post. I worked with the downloadable workbook and did some experimenting to see how each part of the formulas worked. Although I understood most of it, I have a question. What if I wanted the results of my search for each person to be listed by column instead of by row?

  18. Mia says:

    Hi all,
    thanks for the contribution, it helped a lot.

    But what if I need to get the average of the multiple values I get?
    Is there a way to get the average of these multiple values directly (without listing them beforehand...my sheet is already busy)?

    thanks a lot.

  19. Matt says:

    What changes would you make to allow these multiple values to be horizontal rather than vertical, as shown?

  20. Diane says:

    Mr. Doo, you are so funny! I did not know the multiple occurrences could be done without a (trial and error) macro.
    You make it fun to make a complicated task a Can - Do ! Thanks!

  21. Julia says:

    Hi,
    It looks super helpful.
    However, whatever I do it feels I'm almost there... but every time it's a mirage.
    I've a (very) big data table consisting of multiple parameters (about 10) for every value in column A. A problem - same A value may (or may not) appear multiple times in my big table. Luckily, the repetition is always in clusters - one after another (and after the cluster ends, there is no more same A).
    The goal - I've a subset of data consisting of arbitrary values of column A (each one repeats only once), and I want to get all the parameters for all them (including for the as much as there is same A values). With you function, it fills nicely automatically for only the first A, but only once (without considering multiple occurrence), and then jumps to the next one.
    Is there a way to solve this (without tediously manually inserting N rows number for N A's)? I prefer not using macro's.
    Thank you,
    Julia

  22. JB says:

    Does anyone know how to summarise the following data to return the record vertically under the expected result?

    Much appreciated ...

    Data is from A1 to D3
    Name "Asset Name#1","Asset Name#2","Asset Name#3"

    hi dear
    i have a list of persons(First name space last name) in column A. multiple values are equal to first name and last name. ie. A kumar, b kumar alok das, alok ranjan. now i want multiple entries of all matching first name or second name as per my choice, what is the solution.

    Hi,
    I have 10 rows. in row 1 there are multiple columns. in few colums some values are present. just i wants to count the coulmn number of first record. how do i get it ?

    example

    A B C D E F G H I J
    10 13 19 12 --> here number 10 position is 3
    11 2 5 8 --> here number 11 position is 1

    Just to say that you have been the only person I've found to bother explaining the rationale behind your function choices. There were other articles on the internet where people didn't bother to make the effort. Many thanks.

  31. Peter says:

    Is there a text character limit to this formula? It works when I enter a few sentences, but not when I have 10 sentences.

    • Hui... says:

      @Peter
      I don't believe so
      There maybe with pre-2007 versions of Excel
      Can you post a sample data

      • Peter says:

        this is the formula I'm running:

        =IFERROR(INDEX(Input!$A$1:$R$201,SMALL(IF(IFERROR(SEARCH($E$2,Input!$D$1:$D$201)>0,FALSE),ROW(Input!$D$1:$D$201)),ROW()-5),COLUMN()),"")

        and when I have this text paragraph on the sheet I'm pulling from, it won't pull in:

        "We do need a fair amount of analysis in advance of the meeting. Let's start with a sensitivity analysis at plan value under various assumptions in terms of what lenders take - say 50% up to 100% in 5% increments. Need to understand dilution at various points to each side as we negotiate. If we can get that in the next hour or so, we can figure out what else would be helpful to negotiations. "

        But when I shorten it to:

        "We do need a fair amount of analysis in advance of the meeting. Let's start with a sensitivity analysis at plan value under various assumptions in terms of what lenders take - say 50% up to 100% in 5% increments."

        It works then..

    3
    8
    10
    12

    Great work in this article! Very well explained!

    But i need some help...

    I want to use the Multiple Occurrences and Multiple Criteria with the Partial Text Search.

    Example:
    1st criteria: G11
    2nd criteria: Varnish
    3rd criteria: 1503/5

    And i want to use in the 3rd criteria only the "1503" to seeach 1503/5, 1503/6 and 1503/7.

    Can you help me with this issue?

  34. Hi chandoo, thanks for your wonderful work.

    I am in stuck to find a solution to extract multiple rows (by using index+ small+ if) and extract the multi columns to its rows.(multicolumn data should be combined as single).
    I repeated the index function three time to get three column's data and combine it with wild character and got the required answer. But feel this can be done in better way. so Could you please help to simplify the below formula in alternative way.

    {=IFERROR(INDEX(Table1,SMALL(IF(Table1[Tag trim]=LEFT(F75,8),ROW(Table1[Tag trim])-1),1),COLUMN(Table1[MAX. LENGTH (mm)
    (22)]))&" X "&INDEX(Table1,SMALL(IF(Table1[Tag trim]=LEFT(F75,8),ROW(Table1[Tag trim])-1),1),COLUMN(Table1[MAX. WIDTH (mm)(24)]))&" X "&INDEX(Table1,SMALL(IF(Table1[Tag trim]=LEFT(F75,8),ROW(Table1[Tag trim])-1),1),COLUMN(Table1[HEIGHT (mm)
    (23)])),"")}

  35. Jose says:

    Hi. Your help in excel is great. It has being very helpfull in a project I am working on.

    I got a question about Multiple Occurrences: I am trying to get all different values from the a same date and return values horizontally.
    It ls like this:

    Date provider
    June 2 A
    June 2 A
    May 3 A
    May 3 A
    May3 B
    April 4 B
    April 4 B
    April 4 B
    April 4 C
    April 4 C
    April 4 A

    Could you please help me with the formula?

  36. Jarek says:

    I've got a lot of hints from this post and was able to get almost there with my task but there is one problem - string length. I have a long list of stuff given in consequtive columns. I need to peak certain type of data (long string) and put them together in one cell. The text type comes after the text, so schematically one raw of the data looks like this (where Ty My Wy Oni etc is the Type and it repeats):
    Text_A Ty Text_B My Text_C Wy Text_D Oni Text_E Ja Text_F Ty Text_G My Text_H Wy Text_I Oni Text_J Ja Text_K Ty Text_L My Text_M Wy Text_N Oni Text_O Ja Text_P Ty Text_R My Text_S Wy

    What I want is "Text_A, Text_F, Tekst_K, Text_P" if the search="Ty"
    The following works if the string in Text_X is <256; if logner -forget it
    =TEXTJOIN(", ";TRUE;IF($C$4:$AL$4="Ty";$B$4:$AK$4;""))
    same with error handling
    =TEXTJOIN(", ";TRUE;IFERROR(IF($C$4:$AL$4="Ty";$B$4:$AK$4;"");""))

    Most of the Index - Small etc solutions take up several cells to work and that is not an option this time. Any hints, please?

    I have been brainstorming this from past couple of months. I work in reporting team and during month end I pull all incident report which has changed priority from P1-P2-P3-P4, P2-P3-P4 or P3 to P4. Currently, I am performing it manually (4000+ count). Below is the sample excel where I would highlight in a different color if priority changes from P1-P2-P3-P4, P2-P3-P4 or P3 to P4. So basically I want to check column A if it has more than 2 similar value it should check the final priority in column B based on Column C's updated time and it should return value as P1-P2-P3-P4, P2-P3-P4 or P3 to P4 in Column D.

    Number Priority Start time
    INC0281369 Priority 2 2017-07-03 13:01:07
    INC0281369 Priority 4 2017-07-03 13:04:29
    INC0281696 Priority 3 2017-07-26 21:20:16
    INC0281696 Priority 4 2017-07-27 00:06:21
    INC0281962 Priority 3 2017-07-01 01:13:41
    INC0281962 Priority 4 2017-07-01 04:21:12
    INC0281974 Priority 3 2017-07-01 01:35:41
    INC0281974 Priority 4 2017-07-01 03:25:14
    INC0281976 Priority 3 2017-07-01 01:40:25
    INC0281976 Priority 4 2017-07-01 03:26:29
    INC0281985 Priority 2 2017-07-01 02:03:38
    INC0281985 Priority 3 2017-07-04 18:29:34
    INC0281987 Priority 2 2017-07-01 02:06:38

    Any help would be appreciated

    You have done a great job, Bravo!
    I want the same result but my "Das hoff" is in multiple sheets. Can you please be kind enough to give me the formula to have the same output but the searches are in different sheets.

    Thanks in advance.

    Hi! Your instruction is great on this however I am still stuck with my formula. I revert back to INDEX/MATCH but I know my data is skewed. I really hope you can help!

    I am working with two worksheets, CREDIT _MEMO_ACCRUAL_MASTER & CM_12 - I will reference them as WS A& WS B.
    WS A is the master where my formula starts in column 15, row 2. My index/match is based on multiple criteria, Invoice # & Sku, to lookup the Original Invoice Date from Index sheet WS B. WS B only contains original invoice date, sku, credit date and amount.

    WS A:
    INVOICE# SKU RESULT FROM WS B
    139591 XYZ (BLANK)
    139612 ABC 12/11/2017

    Currently in "RESULT FROM WS B"
    =IFERROR(INDEX(CM_12!$B$2:$B$602,MATCH(CREDIT_MEMO_ACCRUAL_MASTER!B2&CREDIT_MEMO_ACCRUAL_MASTER!F2,CM_12!$D$2:$D$602&CM_12!$F$2:$F$602,0)),0)

    The trouble is this:
    WS B has reoccuring original invoice date and sku. In other words - invoice 139612 on credit date 11/30/2017 may have several different "original invoice dates" and 10 returned skus, therefore show up in 10 different rows.
    WB S:
    Invoice # Original invoice date Credit date SKU
    139612 08/08/2017 11/30/2017 1234
    139612 08/21/2017 11/30/2017 5678
    139612 08/30/2017 11/30/2017 1234

    I need a formula that will recognize the exact original invoice date for an invoice # and sku. Currently my index/match as you know only results in the first instance.

    I tried your index/small/if formula but it didnt work for me. index/small/if is very new to me so I am sure i was doing it wrong somewhere.

    I really hope you can help!
    Happy New Year!

    Hi All,

    Great post, which I come back to multiple times !!

    Can anyone explain to me how to amend the formula when you want to either exclude (e.g. all the lines NOT concerning DAS HOFF) rather than select a certain value, or when you want to allow more than one value (e.g. the lines where DAS HOFF is linked to US or UK)

    Thanks for your help.

    Geert.

    Great post!

    How do I get the output of the multiple occurrences into another coloum instead of on the same row?

    Thanks

    Thanks for the aide. I have been using this formula but the step by step explanation you have given makes me understand now completely the inside chemistry as to what is happening. Keep it up.

    Hi Chandoo

    I've replicated your exact spreadsheet and it works perfectly, thanks! For my actual application, I'm using a Named Table where:

    $B$1:$B$20 = Chandoo[PointlessThing]
    $A$1:$A$20 = Chandoo[Person]

    Replacing the fixed cell references with the Table[Column] values the array formula produces an output that is one cell below what the actual value is. For example, if my lookup value is Das Hoff with the named table I get Amnesiac, Raging, Limb King, Krautrock, Erasing. When I just use the cell references I get Talented, Knightrider, Baywatcher, SpongeBob, Krautrock. As you can see, outputs when using the named table are actually one row below the intended output.

    I've varied the formula, from completely deleting the -2 in ...ROW()-2, to trying 0-3. I can never get the named table formula to output the same results as the cell reference formula.

    I've noticed the lateral distance doesn't matter, only the relative horizontal distance, so for that reason my named table formula starts in cell E3, referencing E2 as the lookup value, and my cell reference formula starts in cell G3, referencing G2 as the lookup value. The Person/PointlessThing columns begin at A1 and B1. The table is named "Chandoo." So my named table references are Chandoo[Person] and Chandoo[PointlessThings].

    As a final note, I'm using data validation, referencing the Person column of the named table as my lookup values in cells E2 and G2.

    • Robert Lawson says:

      So I retried the formula with dragging ranges (which automatically populates the range name) and I got this:

      =IFERROR(INDEX(Chandoo[[#All],[PointlessThing]],SMALL(IF(Chandoo[[#All],[Person]]=$F$3,ROW(Chandoo[[#All],[Person]])),ROW()-2),1),"")

      And it works!

      Originally I was hand typing it to make sure I got it all right and was entering this:

      =IFERROR(INDEX(Chandoo[PointlessThing],SMALL(IF(Chandoo[Person]=$F$3,ROW(Chandoo[Person])),ROW()-2),1),"")

      As you can see, I was missing [#All] preceding the column reference.

      That said, this also works when referencing another sheet in the workbook, as long as the relative positions stay the same.

      What I've run into now is this: Where I want the multiple occurrences to appear are 'Visit Tear Sheet!F12:F16'

      The drop-down data validation is Visit Tear Sheet!F8

      The table location is 'Visit Log'B49:C148

      I've kinda buried the table at the bottom of a spreadsheet because I don't want non-tech saavy users to easily find it and screw it up. I know I could let it rest on a separate sheet starting at A1 like our sample data set, but I'm trying to keep the number of sheets to a minimum to keep the weight of the file down.

  44. Jimbob says:

    Instead of the results being in downward rows is it possible to put them in the next columns?

  45. Jim says:

    Have you ever had to do this using Power Query? Or, know of a way to do something similar, but using Power Query? I have a huge workbook that uses a method similar to yours, but it's way to slow using the SMALL and ROW formula so I'm trying to speed it up, but by using PQ. Thank you so much in advance for any help!

  46. Christian says:

    Can this method work with wildcards? I tried but I could not find a way to make it work.
