The Reasons Why VLOOKUP Formula is Not Working
#1 Lookup value is not in the first column of the table array
The VLOOKUP function is that it can only look for values on the leftmost column in the table array and if lookup value is not in the first column of the array, and you will see the #N/A error.
Assume that you want to retrieve the number of sales for product “word”, and you can use the following VLOOKUP function:
=VLOOKUP(E2,A2:C6,2,FALSE)
You should see that the #N/A error message will be shown, because the lookup value “word” in Cell E2 appears in the second column of the table array argument A2:C6.
To correct the #N/A error, and you need to adjust your VLOOKUP to reference the correct column.
#2 #N/A Error in Exact Match VLOOKUP
If you are starting with an exact match and the exact value “Words” is not found, and the #N/A error is returned. Type the following VLOOKUP formula in Cell F2:
=VLOOKUP("Words",B2:C5,2,FALSE)
#3 #N/A Error in Approximate Match VLOOKUP
If you are starting with an approximate match using VLOOKUP function, and your formula may be return the #N/A error message caused by the following two cases:
If the lookup column is not sorted in ascending order.
If the lookup value is smaller than the smallest value in the lookup array.
Remove VLOOKUP #N/A Error
When using VLOOKUP function and it can not find any data or when you haven’t entered a lookup value in VLOOKUP formula, and you should get an #N/A error message. And this error message is not helpful at all. You may be want to remove it in your worksheet. And you can use the IFERROR function to remove #N/A error message in VLOOKUP function.
You can put the above VLOOKUP function into the IFERROR function as a new formula, refer to the below formula based on the IFERROR function and VLOOKUP function, it returns a blank string instead of #N/A error.
=IFERROR(VLOOKUP("Words",B2:C5,2,FALSE),"")
If you are using Excel 2003, and you can use the IF function and the ISERROR function, as the IFERROR function is not available in Excel 2003, type:
=IF(ISERROR(VLOOKUP("Words",B2:C5,2,FALSE)),"",VLOOKUP("Words",B2:C5,2,FALSE))
You need to put the VLOOKUP function in there twice to remove #N/A error message in Excel 2003.
