This article describes the formula syntax and usage of the ISFORMULA function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) 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.
The workbook below shows examples of this function. Inspect them, change existing formulas, or enter your own formulas to learn how the function works.
To work more in-depth with the example data in Excel, download the embedded workbook to your computer, and then open it in Excel.
