Sample ODS File Download

ODS is the spreadsheet counterpart to ODT in the OpenDocument family — LibreOffice Calc's native format, also readable and writable by Excel and Google Sheets. It supports formulas, multiple sheets, pivot tables, and macros, so it isn't a stripped-down alternative to XLS/XLSX so much as a differently-governed one.

The practical reason to keep an ODS test file around: spreadsheet import code that's only ever been tested against XLSX can fail in subtle ways on ODS input — different formula function names, different date serialization — even though both are "just spreadsheets" on the surface.

Download the sample here to check that assumption before a user uploads a real ODS file to your app.
