How to Use the Less Than or Equal to Function in Excel: A Step-by-Step Guide

To use the less than or equal to function in Excel, you simply need to type the formula <= followed by the value you are comparing to. For instance, if you want to check if the value in cell A1 is less than or equal to 10, you would type =A1<=10 in a different cell. Once you hit enter, Excel will display TRUE if the condition is met and FALSE if it’s not.

After completing the action, Excel will evaluate the data based on the criteria you’ve set and return a TRUE or FALSE result. This can be helpful for filtering data, performing calculations, or setting up conditional formatting rules.


Excel, the spreadsheet software giant, is a tool known for its robust features that make data analysis a breeze. Whether you’re a student crunching numbers for a project or a business analyst looking into sales trends, Excel’s functionalities cater to a wide range of needs. Among its plethora of features is the ability to compare values using logical functions, such as the less than or equal to (<=) function.

This simple yet powerful function allows users to perform comparisons between data points. It is not only crucial for data validation but also for making informed decisions based on the dataset at hand. As a go-to comparison operator in Excel, mastering the less than or equal to function is essential for anyone looking to harness the full potential of Excel’s capabilities. It’s relevant to individuals dealing with budgets, performance metrics, inventory management, and even academic research.
