If the value is an #N/A error, the function returns a specified value; otherwise returns the value itself. In this guide, we’re going to show you how to use IFNA Excel function and also go over some tips and error handling methods.

IFNA Excel Syntax

IFNA(value, value_if_na)



The value you want to test.


The value to be returned if the value argument is #N/A.


=IFNA(F3,"beware the error!")
formula demonstrates a simple use case. The formula evaluates the value in cell F3, which has a formula that returns an #N/A error. Since the error is in cell F3, the formula returns the string value entered for the value_if_na argument. On the other hand, the formula in cell G5 returns the argument value, because F5 doesn't give an #N/A error.
