Excel Information Functions

This page lists the current, built-in Excel Information Functions. These functions mainly provide information about the contents of cells, such as data types and properties. There are also functions that provide information on a cell's formatting or location and on the current operating environment.

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.
