Format guide
What is ODS?
OpenDocument Spreadsheet is an OpenDocument Spreadsheet workbook (ZIP of XML) used by LibreOffice and compatible suites, created by OASIS (2005). ODS is the open alternative to XLSX for tables, formulas, and charts. It travels well through LibreOffice/OpenOffice; convert to XLSX or CSV when collaborators live entirely in Microsoft Excel or Google Sheets.
