Excel ISERROR Function is a handy tool for checking if a cell contains an error and returning a simple TRUE or FALSE value. It’s quite useful for error handling in Excel spreadsheets.

## Syntax

**ISERROR(value)**

## Arguments

value | The value you want to test for an error. This can be a cell reference, a formula, or a constant value. (Required) |

## How to use

To use the ISERROR function, follow these simple steps:

- Enter a formula in a cell that might potentially result in an error.
- Use the ISERROR function to check if the formula produces an error. For example:

1 |
=ISERROR(A1) |

This formula checks if cell A1 contains an error. If A1 contains an error, it will return TRUE; otherwise, it will return FALSE.

You can also use this function in combination with other Excel functions. For instance, you can use it with the IF function to handle errors gracefully:

1 |
=IF(ISERROR(A1), "Error occurred", A1 * 2) |

In this example, if cell A1 contains an error, the formula will display “Error occurred.” If A1 doesn’t contain an error, it will perform the calculation and display the result.

## Examples

Here are some examples to illustrate how the ISERROR function works:

Formula | Result |

=ISERROR(5/0) | TRUE |

=ISERROR(A2) | FALSE |

=IF(ISERROR(B1), “Error”, B1*2) | Error (if B1 contains an error) or the result of the calculation (if B1 is a valid number) |

## Additional Information

If you want to handle specific error types, you can use other error-checking functions like ISERR, ISNA, ISBLANK, and IFERROR in Excel. These functions allow you to perform more fine-grained error handling based on the type of error encountered.
