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.
