The ISDATE syntax in Excel is used to check whether a given value is a valid date. The syntax is: ISDATE(value) Here, "value" is the cell reference or the value you want to check. The ISDATE function returns TRUE if the value is a valid date, and FALSE if it is not. It can be used to validate dates entered by users, or to check if a cell contains a date before performing calculations or formatting based on the date.

If the cell contains a valid date, the formula will return TRUE, otherwise it will return FALSE. Note that the ISDATE function does not consider the formatting of the cell, it only checks if the value is a valid date.
