We can use the excel IFNA function to generate a custom result when a formula ought to display the #N/A error. This function doesn’t detect other errors apart from the #N/A error. The steps below will walk through the process.
Figure 1: How to Use the Excel IFNA Function
Formula
=IFNA(VLOOKUP(D4,A4:B10,2,FALSE),"Not applicable")
Setting up the Data
- We will set up the data by inputting the SUBJECTS for a student in Column A
- Column B contains the scores for each subject
- Column E is where we want the formula to return the result. We will use a VLOOKUP formula to check for the scores of the subjects if they are in the range (A4:B10)
Figure 2: Setting up the Data
Excel IFNA Function
- We will click on Cell E4
- We will insert the formula below into the cell
=IFNA(VLOOKUP(D4,A4:B10,2,FALSE),"Not applicable")
- We will press the enter key
Figure 3: Result of VLOOKUP for Cell E4
- We will click on Cell E4 again
- We will double-click on the fill handle (the small plus sign at the bottom right of Cell E4) and drag down to copy the formula into the other cells

Without the IFNA Function
Without the IFNA Function, the formula for VLOOKUP is: =VLOOKUP(D4,A4:B10,2,FALSE)
. If we clear the data from Cell E4 to Cell E6 where our result is and input the formula below, our result will be like figure 5.
Formula: =VLOOKUP(D4,A4:B10,2,FALSE)
