Excel Logical Functions

This page lists the current, built-in Excel Logical Functions. These functions are provided by Excel, to help you to work the logical values, TRUE and FALSE. They include boolean operators, conditional tests and functions to return the constant logical values.

The functions have been grouped into categories, to help you to find the function you need to perform a specific task. Selecting a function name will take you to a full description of the function, with examples of use.
