ISREF function

Excel’s ISREF function is a simple yet powerful tool that helps you determine whether a given cell reference is valid. It’s like a detective that checks if a cell address exists in your Excel workbook. This function helps ensure data integrity and avoid errors in your spreadsheets.




referenceThe cell reference you want to check. It can be a cell address like A1, a named range, or a cell with a structured reference.

How to Use

To use the ISREF function, follow these simple steps:

  1. Start with an Excel worksheet open.
  2. Select the cell where you want to display the result of the ISREF function.
  3. Enter the following formula in the selected cell: Replace “reference” with the cell reference you want to check.
  4. Press Enter, and Excel will return either TRUE (if the reference is valid) or FALSE (if the reference is not valid).

Let’s take a look at a few examples to understand how the ISREF function works:

Example 1: Checking if cell A1 is a valid reference:

Result: TRUE (if A1 contains a valid reference)

Example 2: Checking if a named range “SalesData” is a valid reference:

Result: TRUE (if “SalesData” is defined as a named range)

Example 3: Checking if cell B3, which contains a text value, is a valid reference:

Result: FALSE (because B3 does not contain a valid reference)
