Excel Tutorial – ISERROR

The ISERROR function in Microsoft Excel is a useful tool for determining if a cell contains an error value. This can be helpful for tasks such as data validation or error checking.

Here’s how to use the ISERROR function:

1. Open a blank Excel spreadsheet.
2. In the cell where you want to display the result of the ISERROR function, type the following formula: =ISERROR(value)
3. Replace “value” with the cell reference or value that you want to check for errors. For example, if you want to check the value in cell A1, you would enter A1 in place of “value”.
4. Press Enter to calculate the result. The result will be TRUE if the value contains an error, and FALSE if it does not.

There are several types of error values that the ISERROR function can detect, including #REF!, #NAME?, #DIV/0!, #N/A, and #VALUE!. For example, if you have a formula that divides a number by zero, the result will be the #DIV/0! error value. You can use the ISERROR function to check for this error and take appropriate action.

For example, let’s say you have a list of numbers in column A and you want to check if any of the cells contain errors. Here’s how the formula would look for the first cell in the list:

=ISERROR(A1)

This formula would check the value in cell A1 and return TRUE if the cell contains an error value, or FALSE if it does not.

I hope this tutorial helps you understand how to use the ISERROR function in Microsoft Excel!
