The function returns a Boolean value based on the outcome – TRUE if there is a formula, and FALSE if not.

The cell or range reference you want to check.
When the ISFORMULA function is used with a range reference, it returns an array of formulas to referenced range. If you do not use the Ctrl + Shift + Enter key combination to generate an array, the formula will return only the first value. Alternatively, you can use a function that works with arrays to retrieve this information.
The following formula uses the INDEX function to get a formula on the 3rd row and 1st columns from an array. That array returns a range reference from the ISFORMULA function.
