ISNA
Tests for the #N/A (Not Available) error value.
Syntax:
ISNA(value)
- Returns TRUE if value is or refers to the #N/A (Not Available) error and FALSE otherwise.
Example:
ISNA(NA())
- returns TRUE, because NA() returns the #N/A error.
ISNA(1/0)
- returns FALSE, because 1/0 is a #DIV/0! error, not a #N/A error.
ISNA(A1)
- where A1 contains "dog", returns FALSE, because "dog" is text, not an error.
