The IFNA function in Google Sheets allows you to handle #N/A errors that may occur in formulas or functions. This can be useful when you want to display a default value or message instead of the #N/A error.

Here’s how to use the IFNA function:

- In the cell where you want to display the result of the IFNA function, enter the formula: =IFNA(value, value_if_na)
- Replace “value” with the formula or function that may return the #N/A error.
- Replace “value_if_na” with the value or message you want to display if the #N/A error occurs.

Here’s an example of how to use the IFNA function:

=IFNA(VLOOKUP(A1, A2:B10, 2, FALSE), “Not found”)

This formula performs a lookup for the value in cell A1 in the range A2:B10 and returns the value from the second column in the same row. If the value is not found, the formula will display the message “Not found” instead of the #N/A error.

I hope this helps! Let me know if you have any questions.
