Excel ISBLANK Function
The ISBLANK function returns TRUE if a cell is empty or blank and FALSE otherwise.
Syntax
=ISBLANK(value)
Arguments
- value (required): The value you want to test if it’s blank or not.
Return Value
The ISBLANK function returns TRUE or FALSE.
Function Notes
- ISBLANK only returns TRUE if value contains nothing at all. If value is a reference to the cell that contains spaces, apostrophes or other non-printing characters that makes the cell look blank; or value is a formula that returns an empty string (""), ISBLANK will return FALSE.
Example
Take the table below as an example. To test the values listed in the table, please copy or enter the formula below in the top cell, press Enter to get the result, and then drag the fill handle (at the lower right corner of the result cell) down to apply the formula to below cells.
