This article describes the formula syntax and usage of the ISFORMULA function in Microsoft Excel.


Checks whether there is a reference to a cell that contains a formula, and returns TRUE or FALSE.



The ISFORMULA function syntax has the following arguments.

  • Reference    Required. Reference is a reference to the cell you want to test. Reference can be a cell reference, a formula, or a name that refers to a cell.


  • If reference is not a valid data type, such as a defined name that is not a reference, ISFORMULA returns the #VALUE! error value.


Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.





Returns TRUE because =TODAY() is a formula.



Returns FALSE because 7 is a number, not a formula.


Hello, world!

Returns FALSE because "Hello, world!" is text, not a formula.



Returns TRUE because, although dividing by 0 results in an error, the cell does contain a formula.
