What is XLSM File Format?

The XLSM file format is another file format used by Microsoft Excel, and it stands for Excel Macro-Enabled Workbook. Similar to XLSB, XLSM files offer additional functionality and capabilities compared to the standard XLSX format.

XLSM files are designed to store spreadsheet data that includes macros. Macros are small programs or scripts that automate tasks within Excel. With the XLSM format, users can create, edit, and execute macros directly within the workbook. This makes XLSM files particularly useful for automating repetitive tasks, performing complex calculations, or creating customized functions.

By enabling macros, XLSM files allow users to enhance the functionality of their spreadsheets. Macros can be written using the Visual Basic for Applications (VBA) programming language, providing a powerful tool for customization and automation within Excel.

One of the main advantages of the XLSM format is its ability to store and execute macros seamlessly. When an XLSM file is opened, Excel enables the macros contained within the file, allowing users to utilize the automation and customization features provided by the macros.

However, it’s important to note that due to potential security risks, some Excel versions may prompt users to enable or disable macros when opening an XLSM file. This is done to protect against potentially malicious macros that could harm the system or compromise data.
