Suppress #N/A returned by Google Sheets vlookup

Question

I have a Google Sheet (example) with a basic vlookup to create a summable column. It returns \"#N/A\" for every search key not found, and attaches the following error to those c

Update 2019-03-01: The best solution is now =IFNA(VLOOKUP(…), 0). See this other answer.

 

You can use the following formula. It will replace the #N/A values returned by VLOOKUP(…) with 0.

=SUMIF(VLOOKUP(…),"<>#N/A")

How it works: This uses SUMIF() with only one value to sum up. So the result is that one value – if unequal to #N/A, according to the condition. If the value is #N/A however, the sum is zero. That's just how SUMIF() works: if no values match the conditions, the result is 0, not NULL, not #N/A.

Advantages:

• Compared to the solution =IF(ISNA(VLOOKUP(…)),"",VLOOKUP(…)) referenced in the question, this solution contains the VLOOKUP(…) part only once. This makes the formula shorter and simpler, and avoids the mistakes that happen when editing only one of the two VLOOKUP(…) parts.

• Compared to the solution =IFERROR(VLOOKUP(…)) from the other answer, errors are not suppressed as that would make detecting and debugging them more difficult. Only #N/A values are suppressed.
