Excel ISLOGICAL Function
When to Use the Excel ISLOGICAL Function in Excel
The ISLOGICAL function in Excel comes in handy when you need to determine whether a given cell contains a logical value. Logical values in Excel are either TRUE or FALSE and are commonly used in conditional statements and logical operations.
The ISLOGICAL function helps you verify the type of data in a cell, ensuring it aligns with your expectations and requirements.
What Excel ISLOGICAL Function Returns
The Excel ISLOGICAL function returns TRUE if the provided value is a logical value (TRUE or FALSE) and FALSE if it is any other data type.
Syntax of Excel ISLOGICAL Function
The syntax of the Excel ISLOGICAL function is as follows:
=ISLOGICAL(value)
Input Arguments
Here is the input argument for the Excel ISLOGICAL function:
● value: The value argument can be a cell reference containing the data or a direct entry of a logical value, a formula that evaluates to a logical value, or any other data type.
Examples of the Excel ISLOGICAL Function
Here are few examples demonstrating the usage of the ISLOGICAL function in Excel:
Example 1: Basic Usage
Suppose you have data in column A, and you want to check whether it is a logical value or not. Enter the following formulas in column B:
It returns TRUE if the given value is a logical value and FALSE if it is any other data type.
Example 2: Count Logical Value Cells
The formula =SUMPRODUCT(–ISLOGICAL(A2:A13)) in Excel is used to count the number of cells within the range A2:A13 that contain logical values.
Let’s break down the formula:
- ISNUMBER(A2:A13): This part of the formula checks each cell in the range A2:A13 and returns an array of TRUE for cells containing logical values and FALSE for cells with non-logical values.
- — (double unary operator): This is a conversion operation that turns TRUE into 1 and FALSE into 0. It coerces the TRUE/FALSE array into an array of 1s and 0s.
- SUMPRODUCT: This function then adds up the values in the resulting array. In this context, it effectively counts the number of cells in the specified range that contain logical values.
So, the overall purpose of the formula is to provide a count of how many cells in the range A2:A13 contain logical values.
Example 4: Applying ISLOGICAL in Data Validation
Suppose you wish to restrict cells A1 to A10 to accept only logical values, preventing the entry of any non-logical values. In such cases, you can utilize the ISLOGICAL function in data validation, as demonstrated below:
- Select the range A1:A10.
- Go to the Data tab and click on Data Validation.
- Choose Custom as the validation criteria.
- Enter the formula: =ISLOGICAL(A1)
- Now, only cells containing logical values will be accepted in the selected range. As depicted in the image below, logical value inputs are accepted in cells A1 and A2; however, when attempting to input a number in cell A3, a restriction message is displayed.
