IFNA Function Examples – Excel, VBA, & Google Sheets

This tutorial demonstrates how to use the Excel IFNA Function in Excel to so something if a calculation results in an #N/A error.

IFNA Function Overview

The IFNA Function tests if a calculation results in an #N/A Error. If not, it displays the calculation result. If so, it performs another calculation.

To use the IFNA Excel Worksheet Function, select a cell and type:

(Notice how the formula inputs appear)

IFNA Function Syntax and Inputs:

=IFNA(value,value_if_na)

value – A value, calculation, or cell reference.

num_digits – What to do if value results in an #N/A error.

How to use the IFNA Function

The IFNA Function tests if a calculation results in a #N/A error, outputting a different value (or calculation) if an error is detected.

=IFNA(VLOOKUP(A2,$E$2:$F$7,2,FALSE),"No Data")

IFERROR Function

Alternatively, the IFERROR Function tests if any error occurs, including #N/A Errors.

=IFERROR(A2,"ERROR_Found")
=IFNA(A2,"ERROR_Found")

Why Use the IFNA Function?

You might be wondering, why should I just use the IFERROR Function? Well when working with lookup functions (like the VLOOKUP), if the lookup value isn’t found the function will return an #N/A.

=IFERROR(VLOOKUP(F3,$A$3:$D$7,4,FALSE),"")

You might only want to handle these valid #N/A errors by setting error values to zero or blank.

=IFNA(VLOOKUP(F3,$A$3:$D$7,4,FALSE),"")

But regular errors will still be shown, allowing you to identify if there is a calculation error with the formula.

IFNA in Google Sheets

The IFNA Function works exactly the same in Google Sheets as in Excel:

IFNA Examples in VBA

You can also use the IFNA function in VBA. Type:
application.worksheetfunction.IFNA(value, value_if_na)
For the function arguments (number, etc.), you can either enter them directly into the function, or define variables to use instead.
