ODS files are primarily linked to Apache OpenOffice Calc and store spreadsheets in the OpenDocument (ODF) format. The file itself is a compressed ZIP archive containing XML documents that hold text, formulas, and embedded media, organized in columns and rows. ODS files also preserve metadata, such as author details. Although commonly used in Calc, they remain compatible with Excel and other spreadsheet applications. The OpenDocument format is an OASIS standard for creating and exchanging office documents
