IFNA Formula


IFNA formula in Excel is very useful, serving as an important tool in your arsenal for advanced data analysis. This formula specifically handles #N/A errors, making it a handy asset when you’re creating formulas in Excel.


The primary purpose of the IFNA formula in Excel is to manage #N/A errors that arise when a specific function or formula doesn’t return a valid value. The IFNA formula evaluates the initial formula, and if it results in a #N/A error, it returns a specified value of your choice.


The syntax for the IFNA formula in Excel is quite simple:

=IFNA(value, value_if_na)


The IFNA formula uses two parameters:

  • value – This is the expression or formula that Excel checks for a #N/A error.
  • value_if_na – This is the custom output that Excel will return if it encounters a #N/A error in the value argument.


The IFNA formula will return the result of the value argument if no #N/A error is present. Conversely, if a #N/A error does arise, it will return the value_if_na.

Usage notes

The IFNA formula is an excellent tool to have on hand when you’re dealing with complex formulas or functions that might result in a #N/A error. It ensures your data analysis remains unimpeded and your Excel spreadsheets retain their professionalism.


You can find and use the IFNA function in Excel 2013 and later versions.

Example #1

Let’s say you have a VLOOKUP formula in cell B2 that might return a #N/A error:

=IFNA(VLOOKUP(C2, E:F, 2, FALSE), "Not found")

In this case, the IFNA formula will return “Not found” if the VLOOKUP formula results in a #N/A error.

Example #2

You can also use the IFNA formula with the MATCH function. Consider the formula:

=IFNA(MATCH(G2, G:G, 0), "No match")

This formula will return “No match” if the MATCH function fails to find G2 in column G.

Example #3

In another example, let’s use the IFNA formula with the INDEX function:

=IFNA(INDEX(A:A, H2), "No value")

If the INDEX function can’t find a value in cell H2 in column A, the IFNA formula will return “No value”.

Example #4

You can also use the IFNA formula in combination with the SUM and VLOOKUP functions:


If the VLOOKUP function can’t find I2 in column B, the formula will return 0.

 Tips and tricks

Remember, the IFNA formula is your best friend when dealing with potential #N/A errors. However, use it wisely, as not all errors should be masked. Some errors could indicate a problem that needs attention.


One limitation of the IFNA formula is that it only handles #N/A errors. It cannot detect or manage other types of errors in Excel.

Common errors and solutions

A common mistake when using the IFNA formula is to forget the second argument, value_if_na. Always provide a custom output for this parameter to ensure your formula functions correctly.

Best Practices

Some best practices when using the IFNA formula include:

  • Always providing a custom output in the value_if_na argument
  • Not using IFNA to mask all errors
  • Regularly checking your data and formulas for potential error sources

List of Related functions

Here are some related functions in Excel that you might find useful:

  • IFERROR: Handles all types of Excel errors
  • ISNA: Checks if a value is #N/A, returning TRUE or FALSE
  • IF: Tests a condition and returns a value if it’s TRUE, and another value if it’s FALSE

Frequently Used with the formulas

The IFNA formula is often used with:

  • VLOOKUP: Searches for a value in the first column of a range and returns a value in the same row from a specified column
  • INDEX and MATCH: Used together, they can find a value at the intersection of a particular row and column in a range
  • Array formulas: They perform multiple calculations on one or more items in an array

Frequently Asked Questions

Q. How can I use the IFNA function to return blank text instead of an error?

To return an empty string when an error is found, use “” as the value_if_na argument in the IFNA formula.

=IFNA(A1/B1, "")

Q. Can the IFNA function handle all types of errors in Excel?

No, the IFNA function can only handle #N/A errors in Excel.

Q. How can I use the IFNA function with VLOOKUP?

You can nest the VLOOKUP function within the IFNA function to manage errors that VLOOKUP may return.

=IFNA(VLOOKUP(E2, A:B, 2, FALSE), "Not found")

Q. Can the IFNA function be used in array formulas?

Yes, you can use the IFNA function in array formulas. Remember to press Ctrl+Shift+Enter after typing the formula to tell Excel it’s an array formula.

Master the use of Excel’s IFNA formula to manage #N/A errors in your formulas. With this guide, you’ll be able to use the IFNA function effectively, keeping your data analysis tasks running smoothly.
