What is XLAM file format?

The XLAM file format is an extension used for Microsoft Excel add-in files. Add-ins are additional programs or functionality that can be added to Excel to extend its capabilities. XLAM files contain macros, user-defined functions, custom toolbars, and other automation features that enhance Excel’s functionality.

XLAM files are saved in a compiled format, which means that the code within the file is pre-compiled and ready to be executed by Excel. This offers improved performance compared to other file formats that store macros in a source code format (such as XLSM files). Additionally, XLAM files are typically password-protected to prevent unauthorized access and modifications to the code.

When an XLAM file is installed as an add-in in Excel, its functionality becomes available across multiple workbooks. This allows users to access and use the macros and custom functions provided by the add-in without having to copy the code to each individual workbook. XLAM files can be distributed and shared with others, enabling consistent automation across different Excel environments.

To use an XLAM file, it needs to be installed as an add-in in Excel. This can be done by going to the Excel Options menu, selecting the Add-Ins tab, and browsing for the XLAM file to add it as an add-in. Once installed, the macros and functions provided by the XLAM file can be accessed and used within Excel.
