This is a guest post by Sohail Anwar.
Let’s not bore you with an intro. You are about to learn a VLOOKUP trick that Lucifer himself would not want you to know. It’s so absurdly powerful that it was developed in a lab and had to be tested on Rocky’s arch nemesis Ivan Drago.
Presenting the Multiple criteria VLOOKUP!
…boring…pass, we’ve seen it.
Oh, have you? Not like this you haven’t. This will change the way you work with Excel.
Let me start with an easy example. Here’s some data and we would love to know what Bb and Dd is.
Easy. Let’s put a helper column in that concatenates the two inputs and do a basic VLOOKUP.
Puh-lease. How boring.
Bye Bye Helper Column, it was nice while it lasted.
With a dash of CHOOSE and sprinkling of Array formulas, we’re about to change the game:
=VLOOKUP($E2,CHOOSE({1,2},$A$2:$A$7&$B$2:$B$7,$C$2:$C$7),2,0) and press Ctrl + Shift + Enter
Without getting into too many details, using the Array creates a makeshift virtual helper column. You don’t have to understand Array formulas to make them work for you. I will lay out the simple structure that you can replicate
VLOOKUP(lookup value, CHOOSE({1,2,...N},Column1 & Column 2 &…& Column N, Result Column),2,0)
Where the lookup value is either something pre-concatenated (like Bb or Dd above) or you are using multiple criteria that you concatenate when entering the lookup value. The CHOOSE structure is easy. Always {1,2} then concatenate (with &) as many columns as you want (that the lookup values will need to look in) and the VLOOKUP’s column number is always 2. Let’s explore another example:
Let’s say we want to look up the Savings Produced for a Director of Grade D who started in 2014. That’s 3 lookup criteria. Let’s follow the structure.
=VLOOKUP(A13&A14&A15,CHOOSE({1,2},A2:A10&B2:B10&C2:C10,D2:D10),2,0) and press Ctrl + Shift + Enter
The two key things to note is that our lookup value is a concatenation of the criteria, in this case I have put the criteria in A13, A14 and A15 (hence A13&A14&A15 is our lookup value). Secondly, in the CHOOSE formula, the ranges in the middle part (A2:A10&B2:B10&C2:C10) have to be concatenated in the same order that the lookup value was concatenated. So we concatenated:
Start Year & Grade & Role
In both the lookup value and lookup columns within the CHOOSE.
I stumbled on this many years ago at work and it is the easiest way to do multiple criteria lookups. Play around and add more criteria…but that’s just the beginning!
When I get that feeling, it’s like Textual Healing
So how can we take this concept and make it even more useful?
First, let me share my story of pain and anguish.
Often when dealing with volumes of text data I make numerous helper columns to deal with the multitude of ways I am presented with names. Anyone who’s reconciled HR data to Finance data for example can appreciate that pain. Finance write their names First Name (column 1) Surname (column 2), then HR provide a spread with Last Name, Surname (column 1), then all of a sudden the Project team join in the fun with First Name, Surname (column 1)! Arrghh!
So I am now left to deal with this chaos via numerous text formulas involving SEARCH, LEFT, RIGHT, MID, LEN and MYSANITY (okay perhaps that last one is my own UDF, my volatile UDF). So, maybe it’s not that bad, but when you’ve been doing it for as long as I have, it gets tedious and you begin to search for efficiency. So, one day like the rebellious closing scene from Dead Poet’s society, I stood on my desk and declared ‘Oh Captain, My Captain’ as I refused to create another ‘helper’ column.
After my colleagues talked me down from the table and reassured me (“There there Sohail, I don’t mind inserting new columns for you occasionally”…”Sure you don’t John, sure you don’t”), I went about finding a less ‘helpful’ way. Would you believe, our new friend the multiple criteria lookup was the answer.
You see, not only can our criteria be cell references but also extra characters! Let’s say we have First Name(Column A), Surname (Column B) and Unique Reference (Column C). Someone gives us a spreadsheet with the names in either a First Name + Surname or Surname, First Name format. We can look this up by including the extra characters in our lookup columns within the CHOOSE.
Look closely at the middle of the CHOOSE since that’s where the magic is. Download the workbook to see the example in action.
We have pretty much instructed the two columns we are looking up to join up in a specific way. First we want them to join up with a space in between. Then the second formula has asked them to join up Surname, comma and space in between, then finally the First Name. So as far as Excel is concerned we have created two virtual helper columns that look like this:
This makes it straightforward for us to look up John Johnson or Johnson, John in them.
There are virtually no bounds to how you can use this Multiple Criteria VLOOKUP. It made my life tremendously easy and I’m sure it makes yours easier too. Do me a favor and let me know in the comments some of the crazy ways you are applying it.
And then if you haven’t already grabbed a copy of Chandoo’s VLOOKUP book I cannot recommend it enough as the ultimate resource in VLOOKUP mastery

Hi,
I solved this in a little different way.
We have 2 lists, one starts at A1 and other at B1, both are vertical arrays.
First thing is define 2 named ranges, list1 and list2:
list1 refers to "=OFFSET(Sheet1!$A$1;0;0;SUMPRODUCT(--(Sheet1!$A$1:$A$1000""));1)"
list2 refers to "=OFFSET(Sheet1!$A$1;0;0;SUMPRODUCT(--(Sheet1!$B$1:$B$1000""));1)"
this way lists will be dynamically sized when you had or remove elements (you can't have blanks and you can't have more than 1000 elements).
Then I use conditional formatting in column A when this formula is true:
"=NOT(ISERROR(MATCH(A1;list2;0)))"
and "=NOT(ISERROR(MATCH(B1;list1;0)))" to list2.
This way we eliminate the need for auxiliary columns or lists.
Hope you like my way! 😀

Simple conditional formatting formula.
Assuming lists vertical lists starting in A1 & B1
To highlight just one column (assume B for example)
Conditional formatting>New Rule>by formula
=MATCH(B1,$A$1:$A$99,0)
Set the cell fill to what ever color you prefer & press OK
To highlight both columns repeat with this formula for cell in column A
=MATCH(A1,$B$1:$B$99,0)
This approach doesn't require named fields or addtl columns

Say I had 1 list in A2:A20 and another in B2:B20.
To format all the items in column A that are repeated in column B I would use the following Conditional Formatting rule.
=IF(ISNA(VLOOKUP(A2,$B$2:$B$20,1,false)),true,false)
All the duplicates are highlighted. It us a very simple example of comparison.
I may be missing something here, but I usually highlight both my lists by holding ctrl eg A1:A20 E10:E40 then choose conditional formatting from the ribbon and then highlight duplicates, and this does it?
Lee, I was perplexed as well. I do the same thing you do with the conditional formating. A drag and click to highlight range and choose highlight duplicates does the trick for me.
I believe these methods are to check if an item from one list also appears in the other list. So if an item mentioned many times in one list if also mentioned in the other list or not.
The Conditional Formatting highlight duplicates feature will do this, but it will also highlight an item if it appears multiple times in the one column or list.
Hi, I would just like to know (if you are willing to share) which image editing program you use to make your image like above, like they are torn apart from bottom? I've been looking for long.
@i48998
Chandoo is on Holidays, but Chandoo uses Paint.Net
Paint.net is a free download available at http://www.paint.net/
.
I use CorelDraw/PhotoPaint
.
We both use the Snipping Tool (a freebe with Win Vista/10)
.
We both use Camtasia for doing screen captures to make animated GIFs where you see animation.
Here is how I would accomplish
(1) Define Names: List_1, List_2
(2) =ISNA(MATCH(D4,List_2,0))-1 (Conditional Format formula List_1)
(3) =ISNA(MATCH(D4,List_1,0))-1 (Conditional Format formula List_2)
ISNA will return 1 if NO Match and O if Match by adding a -1 will make: NO Match 0 and Match a -1 which is True
Hi all
this my first Post here
i think we can take Unique List for tow list to know what is not Duplicate By this Array formula
=IFERROR(INDEX($D$6:$D$33,SMALL(IF(ISERROR(MATCH($D$6:$D$33,$B$6:$B$33,0)),ROW($D$6:$D$33)-ROW($D$6)+1),ROWS($J$5:J5))),"")
and this one for Duplicate Value
=IFERROR(INDEX($D$6:$D$33,SMALL(IF(ISNUMBER(MATCH($D$6:$D$33,$B$6:$B$33,0)),ROW($D$6:$D$33)-ROW($D$6)+1),ROWS($J$5:J5))),"")
Don't forget to Enter This Formula by Pressing Ctrl+Shift+Enter
without wanting to ruthlessly self promote here, I do have an addin that does neatly compare two ranges, not just in columns, so you might want to check that out.
Having said that this is a pretty neat solution if you dont want to be going down the VBA or purchase route. I like it
however, could you not do something with the remove duplicates feature in Excel 2010 and then compare the resulting data set?
Hi, Chandoo! I've found yesterday your Excel website... What can I say? It's just awesome, Excellent. Being a developer for 30 years, more than 15 with Office products, and wow!, how many things I discovered in a couple of hours, and what pretty resolved.
I decided to take the long path of the newbies and read all your examples and write down by myself all of them, and when I arrived to this (the comparison of two lists) I think I've found a problem:
a) in "Step 4: Apply conditional formatting to Second List - Use the same logic, but this time the rule becomes =COUNTIF(count1s,$H6)" it should say "Step 4: Apply conditional formatting to Second List - Use the same logic, but this time the rule becomes =COUNTIF(count1s,$H6)>0", but this is a typing error that I believe all of us here might have discovered and corrected
b) the very problem: I wrote down two different lists, in different ranges, and with different number of elements, I specified the equivalent conditional formats, et non voilá!, I didn't get what expected. So I downloaded your example book, I checked range names, formulaes, conditional formats and all OK. So I copied -just values- from my book to yours, and I still couldn't achieve the goal.
I'm using Excel 2010 in spanish, I'm from Buenos Aires (Argentina), and my book is at your disposition whenever you considerate it appropiate.
Thanks in advance for your time, and again my congratulations for your work here.
Best regards.

Comparison of 2 lists visually with highlights
Author: SirJB7 / Date: 11-Dic-2011
Pros: no duplicated tables, no matrix formulaes, no named ranges, no VBA code, just conditional formatting
Cons: not found yet, comments and observations welcome
Features:
a) standard problem: highlights in orange/yellow elements existing in the other list
b) optimized problem: idem a) plus highlights in red/violet first occurrence of elements existing in the other list
Sheet contents:
a) conditional format, 1 rule per list (2 methods used)
A1:A20, first list
B1:B20, second list
a1) range A1:A20, condition =NO(ESERROR(BUSCARV(A1;B$1:B$20;1;FALSO))), format Orange ---> in english: =NOT(ISERROR(VLOOKUP(A1,B$1:B$20,1,FALSE)))
a2) range B1:B20, condition =CONTAR.SI(A$1:A$20;B1)>0, format Yellow ---> in english: =COUNTIF(A$1:A$20,B1)>0
b) conditional format, 2 rules per list (2 methods used)
D1:D20, first list
E1:E20, second list
b1) range E1:E20, condition 1 =Y(NO(ESERROR(BUSCARV(D1;E$1:E$20;1;FALSO)));COINCIDIR(D1;D$1:D$20;0)=FILA(D1)), format Red ---> in english: =AND(NOT(ISERROR(VLOOKUP(D1,E$1:E$20,1,FALSE))),MATCH(D1,D$1:D$20,0)=ROW(D1))
same range, condition 2 and format 2, same as a1)
b2) range E1:E20, condition =Y(CONTAR.SI(D$1:D$20;E1)>0;COINCIDIR(E1;E$1:E$20;0)=FILA(E1)), format Violet ---> in english: =AND(COUNTIF(D$1:D$20,E1)>0,MATCH(E1,E$1:E$20,0)=ROW(E1))
same range, condition 2 and format 2, same as a2)
Personally I like the a2) and b2) solutions, I think the formulaes are prettier.
I still don't know the rules of this website and forum, but it any precept is infringed I'm willing to share the workbook with the solution. If it breaks a rule, I apologize and promise that won't happen again.
Best regards for all!
Dear All i have a complicated situation...
1. I have two sheets of data Sheet1 and Sheet2 (from various sources) - Both of these contain data matching and Not matching as well..
2. Now for me i need to build an excel where in i need to get sheet 3 with values that are present in a column of Sheet 1.
What ever Sheet 1 doesn't have i dont want those rows from sheet 2 to be populated into Sheet3.
Can any one help me out.
Hi Team
The above example is to compare partial name from 2 different columns.
If I want to cross check it in a single column. I have both correct and partial correct/match entries in a column. Is there any way I can find both the entries in the column.
Regards
