ODS

ODS (OpenDocument Spreadsheet) is the open standard spreadsheet format developed by OASIS, used natively by LibreOffice Calc and Apache OpenOffice Calc. It stores spreadsheet data, formulas, charts, and formatting in XML compressed within a ZIP archive, ensuring transparency and long-term accessibility. ODS is a fully open, non-proprietary alternative to Microsoft Excel's XLS and XLSX formats and is supported by Google Sheets.

XLS

XLS is the legacy binary spreadsheet format used by Microsoft Excel from 1987 through the Office 2003 era, based on Microsoft's proprietary Binary Interchange File Format (BIFF). It stores worksheets, formulas, charts, and macros in a binary structure that requires Microsoft's format specification to parse correctly. XLS remains common in older enterprise systems and when compatibility with legacy versions of Excel is required.
