In Google Sheets, ISERR is a function that checks whether the given value is an error or not.
It returns TRUE if the value is any error except #N/A, or FALSE if the value is not an error or is #N/A.
This function is useful in situations where you want to check whether a cell contains an error or not, and then perform certain actions based on that result.
