ESTVIDE(ISBLANK)
Checks whether a cell is empty.
What it does
ISBLANK returns TRUE only for a cell with nothing in it. Use it to flag missing entries, often inside IF.
Syntax
=ESTVIDE(value)Arguments in square brackets are optional, and … means you can add more of the same. In this Excel language, arguments are separated by ;
Arguments
- value
- The cell to check.
Example
Is the email address in row 2 missing?
| A | B | |
|---|---|---|
| 1 | Missing? | |
| 2 | VRAI | |
| 3 | kai@example.com |
The formula in B2:
=ESTVIDE(A2)Result: VRAI
A2 is empty, so the result is TRUE. A3 has an address and would give FALSE.
Common mistakes
- Cells that only look empty. A space, or a formula that returns
"", makesISBLANKreturn FALSE. To treat both as empty, testA2=""instead. - Putting the address in quotes.
ISBLANK("A2")checks the text A2, which is never blank.
