You can use the IFERROR function to trap and handle errors in a formula. IFERROR returns a value you specify if a formula evaluates to an error; otherwise, it returns the result of the formula.
Syntax
IFERROR(value, value_if_error)
The IFERROR function syntax has the following arguments:
- value Required. The argument that is checked for an error.
- value_if_error Required. The value to return if the formula evaluates to an error. The following error types are evaluated: #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL!.
Remarks
- If value or value_if_error is an empty cell, IFERROR treats it as an empty string value ("").
- If value is an array formula, IFERROR returns an array of results for each cell in the range specified in value. See the second example below.
IFERROR Function is the most favorite function of finance professionals. It is frequently used with VLOOKUP function.
| ◢ | A | B | C | D | E |
|---|---|---|---|---|---|
| 1 | Quota | Units Sold | Formula | Description | Result |
| 2 | 210 | 35 | =IFERROR(A2/B2, "Error in calculation") | Checks for an error in the formula in the first argument (divide 210 by 35), finds no error, and then returns the results of the formula | 6 |
| 3 | 55 | 0 | =IFERROR(A3/B3, "Error in calculation") | Checks for an error in the formula in the first argument (divide 55 by 0), finds a division by 0 error, and then returns value_if_error | Error in calculation |
| 4 | 23 | =IFERROR(A4/B4, "Error in calculation") | Checks for an error in the formula in the first argument (divide "" by 23), finds no error, and then returns the results of the formula. | 0 |
When VLOOKUP Function returns error, it means, the lookup value does not exist in the range and we want to hide this error. To control this error we use IFERROR Function.
