IFNA Formula Syntax

=IFNA(VLOOKUP(A1, B1:C10, 2, FALSE), "Not Found")

Example Use Case

Handling #N/A errors with an alternative result

Understanding the IFNA Formula

The IFNA function in Excel evaluates an expression and returns an alternative value specifically for #N/A errors, otherwise returns the original result. It's a targeted error-handler—like improving lookup results when values aren't found.

IFNA(VLOOKUP(A1, B1:C10, 2, FALSE), "Not Found") returns lookup results or "Not Found" for #N/A errors. It takes a value and value_if_na, providing cleaner handling than IFERROR when you only care about #N/A situations.

Why Use IFNA?

IFNA focuses on #N/A—think lookup refinement or search functions. Its specificity preserves other error types for debugging, making it perfect for lookup-heavy worksheets where "not found" is an expected scenario.

Example with Sample Data

Expression, Fallback	Formula	Result
VLOOKUP("key", data, 2), "Not Found"	=IFNA(VLOOKUP("key", data, 2), "Not Found")	Not Found
5, "Not Found"	=IFNA(5, "Not Found")	5
10/0, "Not Found"	=IFNA(10/0, "Not Found")	#DIV/0!

IFNA targets specifically: handles #N/A errors, passes other errors through. It's a lookup refiner.
