The ISNA function is an Information Function. It is is used to return information about the status of a cell, or specifically another functions results. The most common use I have for this function is to validate the VLOOKUP function. If the VLOOKUP function is looking for a value that can not be found in the lookup range, then it will return #N/A as the result. Thus it is good to wrap that function in an IF Statement using the ISNA function to replace the #N/A results with something else – e.g. a text string such as “error” or maybe a zero.



Remember the ISNA function returns a TRUE or FALSE. These equate to a 1 or 0 so can be used in formulas such as array formulas as well.
