ISBLANK

Checks whether the referenced cell is empty.

Sample Usage

ISBLANK(A2)

IF(ISBLANK(B1),,A1/B1)

Syntax

ISBLANK(value)

• value - Reference to the cell that will be checked for emptiness.

  • ISBLANK returns TRUE if value is empty or a reference to an empty cell, and FALSE if it contains data or a reference to data.

Notes

• ISBLANK returns FALSE if the referenced cell has any content, including spaces, the empty string (""), and hidden characters. In case of unexpected FALSE results, try clearing the cell again to remove any hidden characters.

• This function is most often used in conjunction with IF in conditional statements.
