» Preventing a Vlookup Function From Returning an Error When an Exact Match Is Not Found

Problem:

We want to create a formula to check whether each number in column B appears in List 1 (Column A).
For each successful search, the formula should return that number.
However, if an exact match is not found, the formula should return a text message to that effect, rather than an error.

Solution:

Use the IF, ISERROR, and VLOOKUP functions as shown in the following formula:
=IF(ISERROR(VLOOKUP(B2,$A$2:$A$9,1,FALSE)),""Number Not Found"",VLOOKUP(B2,$A$2:$A$9,1,FALSE))



List1__Numbers to Check____Result
8______2___________________Number Not Found
5______7___________________7
3______10__________________Number Not Found
7______6___________________6
