ODS is the spreadsheet file format used by LibreOffice and OpenOffice. Based on the OpenDocument standard, it supports formulas, charts, and cell formatting. ODS is a free and open alternative to Microsoft Excel’s XLSX format.
XLSX is the modern Excel spreadsheet format introduced with Microsoft Office 2007. It uses ZIP compression and an XML-based structure, resulting in smaller files and better compatibility. XLSX supports advanced spreadsheet features and is widely used in business and data analysis.
