What is XLSM file format?
The XLSM file format is an extension of the XLSX file format used for Microsoft Excel workbooks. Similar to XLSX, it is based on the Open XML file format and is associated with the Excel application. The “M” in XLSM stands for “macro-enabled”, indicating that it supports the inclusion of macros.
XLSM files store spreadsheet data, including worksheets, formulas, charts, and other elements commonly found in Excel workbooks. Additionally, XLSM files allow the embedding of VBA (Visual Basic for Applications) macros within the workbook. Macros are scripts written in VBA that automate tasks, perform calculations, and interact with the spreadsheet data.
By including macros in XLSM files, users can create customized functions, automate repetitive tasks, and enhance the functionality of their Excel workbooks. Macros can be written to manipulate data, generate reports, perform complex calculations, or interact with other applications.
When opening an XLSM file, Excel prompts the user to enable or disable macros due to security concerns. Enabling macros allows the embedded VBA code to execute, while disabling macros prevents potential security risks associated with malicious code.
XLSM files provide advanced features and customization options for Excel users who require automation beyond the capabilities of the standard XLSX format. They are commonly used in business environments, financial modeling, data analysis, and other scenarios where complex calculations and automation are necessary.
