About Microsoft Excel
Modern Excel workbooks use Office Open XML (OOXML) formats introduced in Excel 2007: XLSX (standard workbooks), XLSM (macro-enabled), XLTX (templates), and XLTM (macro-enabled templates). These formats store spreadsheet data as compressed XML files inside a ZIP container, enabling formulas, pivot tables, charts, conditional formatting, and better data recovery than legacy binary formats.

Excel is the industry standard for spreadsheet work, compatible with Google Sheets, LibreOffice Calc, and data analysis tools. For sharing, archiving, or cross-platform viewing, converting to PDF preserves your formatting and layout. Legacy binary .xls files (1997-2003) are supported directly; for complex workbooks with advanced features, re-saving as XLSX may improve fidelity.
