ESTERREUR(ISERROR)
TRUE when a value or calculation is any error.
What it does
ISERROR returns TRUE when its argument is an error of any kind (#DIV/0!, #N/A, #VALUE! and so on) and FALSE otherwise. It is useful to flag rows that fail; to replace an error with another value, IFERROR is shorter.
Syntax
=ESTERREUR(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 or calculation to check, such as
B2/C2.
Example
Pens have 0 units. Does dividing their cost by their units fail?
| A | B | C | D | |
|---|---|---|---|---|
| 1 | Item | Cost | Units | Fails? |
| 2 | Pens | 12 | 0 | VRAI |
The formula in D2:
=ESTERREUR(B2/C2)Result: VRAI
12 divided by 0 gives #DIV/0!, which is an error, so the result is TRUE.
Common mistakes
- Writing
IF(ISERROR(x),0,x)and repeating the calculation.IFERROR(x,0)does the same once. - Hiding errors you should fix. A #N/A from a misspelled lookup value is worth seeing.
