The Excel ISFORMULA function is a logical function that checks if a cell contains a formula. It returns TRUE if the cell contains a formula, and FALSE if the cell does not contain a formula. This function is helpful in determining whether a cell’s value is the result of a formula or not. In this blog post, we will explain the purpose, arguments, return value, syntax, and examples of the Excel ISFORMULA function.
Excel ISFORMULA Function Summary
Excel’s ISFORMULA function is an Information function that allows you to test a cell and determine whether it contains a formula. When applied to a cell, the function returns TRUE if the cell contains a formula and FALSE if it does not. This function can be useful for validating data and automating calculations in your spreadsheets.
ISFORMULA Function Purpose
The purpose of the Excel ISFORMULA function is to determine whether a cell contains a formula or not. It is useful for ensuring the accuracy and reliability of data in a worksheet. The function can be used to perform different actions based on whether a cell contains a formula or not. For example, you may want to format cells that contain formulas differently from cells that contain only values.
ISFORMULA Function Arguments
The Excel ISFORMULA function only takes one argument, which is the cell reference or range that you want to check.
ISFORMULA Function Return Value
The ISFORMULA function returns a Boolean value of TRUE or FALSE. If the cell reference or range contains a formula, the function returns TRUE. If the cell reference or range does not contain a formula, the function returns FALSE.
ISFORMULA Function Syntax
The syntax for the Excel ISFORMULA function is as follows:
=ISFORMULA(reference)The reference argument is the cell reference or range that you want to check.
ISFORMULA Function Examples
The ISFORMULA function in Excel is a handy tool that helps users identify cells that contain a formula. It is particularly useful when working with large and complex spreadsheets. Here are some examples of how you can use the ISFORMULA function:
Checking if a single cell contains a formula
Suppose cell A1 contains the formula “=SUM(A2:A5)”.
To check if cell A1 contains a formula, you can use the following formula:
=ISFORMULA(A1)
This will return TRUE as you can see in the example above.
Checking if a range of cells contains a formula:
Suppose you have a range of cells A1:A5, where A1 contains a formula and the other cells contain values. To check if any cell in the range contains a formula, you can use the following formula:
=SUMPRODUCT(--ISFORMULA(A1:A5))
This formula will return 1 as we can see above, which indicates that at least one cell in the range contains a formula.
Excel ISFORMULA Function Notes
- The ISFORMULA function can be used in combination with other logical functions to perform more complex calculations.
- This function only checks if a cell contains a formula, not if the formula is valid or not.
