XLSXXLSM

XLSXXLSM is a file extension typically associated with Microsoft Excel spreadsheet files. Specifically, it indicates a saved version of an Excel workbook that may contain macros or VBA (Visual Basic for Applications) code. The "XLS" prefix generally denotes an older Excel format, while the "XLSX" format is the default for modern Excel versions. The inclusion of "M" signifies that the file is macro-enabled. These files are used for storing data in a tabular format, and the macro-enabled nature allows for the automation of tasks and the creation of custom functionalities within the spreadsheet. When opening an XLSXXLSM file, users might be prompted to enable content or macros, depending on their security settings. This is a security measure to prevent the execution of potentially harmful code. The XLSXXLSM format is distinct from the standard XLSX format, which does not support macros. This distinction is important for users who need to share spreadsheets with automated features or who are working with older Excel versions that may not fully support the newer macro-enabled formats.
