XLSX

Microsoft Excel Open XML Spreadsheet

XLSX is a widely used file format for spreadsheets, developed by Microsoft as part of the Office Open XML standard, succeeding the older XLS format. It is supported by Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications, ensuring cross-platform compatibility. The format is based on XML and stored in a compressed ZIP container, enabling features like advanced formulas, charts, conditional formatting, and support for large datasets while maintaining smaller file sizes compared to its predecessor.

XLSM

Microsoft Excel Macro-Enabled Spreadsheet

XLSM is a file format used for Excel spreadsheets that support macros, enabling automation and advanced functionality within the document. It is primarily used with Microsoft Excel but can also be opened by other spreadsheet applications like LibreOffice Calc and Google Sheets with limited macro support. The format is based on the Open XML standard, storing data, formulas, and VBA (Visual Basic for Applications) macros in a compressed ZIP container, allowing for efficient storage and advanced features like conditional formatting, pivot tables, and embedded macros.
