Format Details
XLSX
XLSX is the default spreadsheet format for Microsoft Excel since Office 2007, built on the Open XML standard and standardized by ISO. It stores worksheets, formulas, charts, pivot tables, and formatting in a compressed ZIP archive of XML files, making it more compact and corruption-resistant than the older XLS format. XLSX is supported by Google Sheets, LibreOffice Calc, Apple Numbers, and virtually every modern data tool.
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.
