Checks if a value is a reference.
This function works the same in Google Sheets as it does in Excel — same syntax and arguments.
ISREF(value)The ISREF function returns TRUE if the provided value is a valid cell reference, and FALSE otherwise. It is commonly used to verify if a formula or a named range points to a valid location in the workbook.
=ISREF(A1)Result: TRUE
A1 is a valid cell reference.
=ISREF("Hello")Result: FALSE
The text string "Hello" is not a cell reference.
Yes, if the named range is defined correctly, ISREF will return TRUE.
