Also, if you use the VLOOKUP function to look up values in a list or table, it’s possible to end up with #N/A errors, particularly when you’re looking for exact matches. Although these errors are annoying, they occur for a good reason—either the value you’re trying to find doesn’t exist, or it does exist but Excel doesn’t perceive it as a match due to a formatting mismatch or other issue.
