Ok, you have learned how to write vlookup formulas. You have also seen some pretty interesting examples of it (1, 2).
But how do you write better VLOOKUP formulas?
Here is a list of 6 tips that work wonders with VLOOKUP writing.
-
Use named ranges
No one likes a VLOOKUP with lots of dollars and cell references. They are unreadable and difficult to debug. So, a better option is to use named ranges in lookup formulas. For eg: =VLOOKUP(valSalesPerson,tblData,3,FALSE) is much more easier to read and understand than =VLOOKUP(G5,$B$5:$G$17,3,FALSE)
-
Make table / list references Absolute
When you need to write lookup formulas in a range of cells, the usual practice is to write first formula and then drag-fill. If you followed above advice and used named ranges, you should be ok with this approach. But if you do use cell references, make sure the table references are absolute, like this: $B$5:$G$17 instead of B5:G17. Here is a nice tutorial explaining the concept of cell references.

Use Tables or Lists [Excel 2003 or above only]
Using named ranges or absolute references is good technique. But they suffer from one nagging limitation. If your source data (where you are looking up) grows or shrinks, you need to adjust the references. A better option? Use tables (or lists in 2003). Learn more about Excel Tables & how to use them.

Check for Errors
VLOOKUP is a powerful formula, alright. But ask it to look up a value that is not the data and it acts up. So you need to handle this. The easiest method is to use IFERROR() formula. Like this: =IFERROR(VLOOKUP(…),”Oops, nothing found!”).
But, IFERROR is a new formula in Excel 2007, so if you are using 2003 or before versions you need to use ISERROR (), like this: =IF(ISERROR(VLOOKUP(…)),”Oops, nothing found!”,VLOOKUP(…))
But, there is another problem. The ISERROR() is not only lengthy, it is also ugly and inefficient as it calculates VLOOKUP twice. So a better approach is to use COUNTIF(), like this: =IF(COUNTIF(column, value you want to lookup)>0,VLOOKUP(…),”Oops, nothing found!”) [more: how to handle formula errors]
-
Use 1 and 0 for last argument
While I do not recommend this, I have seen many do this in practice. You can use 1 and 0 for last argument in VLOOKUP to make the formula shorter. The formula =VLOOKUP(value, range, column #, FALSE) is same as =VLOOKUP(value, range, column #, 0). Similarly you can use 1 for TRUE.
What more, you can even omit the last argument if it is 0, like this: =VLOOKUP(value, range, column #, ) Remember, you must place a comma (,) after the column number if you are planning to use this.
-
Use VLOOKUP only when you need it
Do you know that formulas like SUMIF() or SUMPRODUCT() can effectively replace VLOOKUP() formulas? For eg. the formula =SUMIF(lookup-range, lookup value, return column range) gives same value as =VLOOKUP(lookup value, total range, 2, false) ? [assuming there is only one match, return column range has numbers]
Similarly, if you just want to find whether a value is in a list or not, use COUNTIF() formula.
That is right. Not only formulas like SUMIF are better, they require no separate error handling. If the value cannot be found, they just return 0.

I’d suggest simply using the subtotal function and filtering the data using the Win/Loss column. You get the same results and the formula is more comprehensible.
@John
That is one option.
There are times however when you want to see the whole data table or a filtered subset and still want to produce summary reports against an unfiltered field.
Is there a particular reason why you are using a comma and the unary (–) operator for the second array in the SUMPRODUCT formula? It seems to work the same if you were to string the arrays together using the asterisk (*). The advantage is that SUMPRODUCT treats the entire string of arrays as a single array.
@Mathew
Your correct, There is no difference.
I thought it may have been easier to explain this method.
Is there a way to do this on a large set of data? As in ~100,000 rows? When I try I get an error because the formula becomes too long. It says the max length of a formula is 8,192 characters. Excel 2010.
How do I incorporate a specific text within a cell for the second array. For instance, – -(C7:C13=”Apple”)
when I chose a specific text the formula does not work.
@RB
I am not sure what is the issue as if I use the sample data in the post the following work fine
Count:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)), –(C7:C13=”L”))
Sum:
=SUMPRODUCT(SUBTOTAL(3,OFFSET(C7:C13,ROW(C7:C13)-MIN(ROW(C7:C13)),,1)),(C7:C13=”L”)*(D7:D13))
You may want to check that there are no leading or trailing spaces in your list of Apples
I should have given a better explanation. Heres my situation. I have a column with cells filled with names like Column 1, Column 2, Pier 1, Pier 2, etc. If the cell just contained Pier and searched for that it works. But because it has other characters in the cell its not recognizing the pier. So how can I extract specific characters of a string of text in this formula?
Hopefully this was a better explanation
Hello-
This formula works pretty well for me except that it slow down excel and prevents some of my macros from working. I was wondering if there was a way to program this in VBA so that excel isn’t always trying to recalculate it. I would like to use a push of a button to get it to run then paste in a cell.
Thanks!
I am trying to sum filtered data in a column, but would want to ignore the negative values in the column. How to go about doing this?
@Akshay
Why not just add a filter to that column to only show the values greater than zero?
The negative values are required for reporting purposes, but their effect on the total is distorting the required output. Please advise.

I’d suggest making a post in the Chandoo.org Forums

I have this working for counting and summing, however, I have a list and for the second array, I need a criteria. That is, I’m looking for b13:b200=”01.??.??” or =left((a1,2) or something like that. These types of criteria matches do not appear to work as I get a blank as a result.
Thanks!
@Bob
As your formula b13:b200=”01.??.??” looks like you are trying to check the first day of the month of the range
What about trying Day(B13:B200)=1
Hai Experts,
i understood this formula well and working fine in MS Excel 2013
but when the same am trying to place in google Spreadsheet it shows error as
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 2014, column count: 1.” and as a result #VALUE! Appears in cell.
Can anyone please help me how would i get it done in Google Spread sheet
or is there any other formula as a substitute for this.
Thank you very much.
thanks for providing this.. but why does excel keeps on prompting Circular referencing in cell D3?
@Vivek
I don’t know
I just downloaded the file and it is working fine and not showing that error
Goto the Formulas, Calculation Options Tab and check that Calculation is set to Automatic
What version of Excel and Windows are you using ?
I know that this forum is for MS Excel, but I am trying to help someone who is working in Google Sheets. The below formula works in Excel but Google Sheets returns:
“SUMPRODUCT has mismatched range sizes. Expected row count: 1. column count: 1. Actual row count: 39000, column count: 1.” and as a result #VALUE! Appears in cell.
This is the same problem asked by Srichirin above. Does anyone know if there is a formula for Google Sheets that will replicate what MS Excel does?
=SUMPRODUCT(SUBTOTAL(3,OFFSET($C$6:$C$39500,ROW($C$6:$C$39500)-MIN(ROW($C$6:$C$39500)),,1)),- -($C$6:$C$39500=H1),($D$6:$D$39500))
Trying to find a SUMPRODUCT formula that counts the word Closed by date for the last 7 days in a filtered list.
=COUNTIF(M:M,”>”&TODAY()-7) works ok for unfiltered count Column M contains Closure dates (blank if open) and Column L is Status Open or Closed

I used this formula and worked like a charm! But, now I’ve been requested to use it but adding not one but two criteria in the same formula. For instance the sum I was doing added negative and positive numbers. I’ve been asked to use the exact same formula but adding that only positive numbers were considered… any idea on how to do this?
How exactly do you do sum filtered cells when two criteria are need not just one?
Thank you so much brother literally I have been struggling since morning to get the sum of the filtered category, however, after reading your blog attentively i got my solution, so thanks a lot once again.
