Why Convert XLSX to ODS?
Converting XLSX to ODS lets you work with Excel spreadsheets in LibreOffice Calc, a free alternative to Microsoft Excel.
About the XLSX Format
XLSX is Microsoft Excel's modern spreadsheet format, the global standard for data organization, financial analysis, and business reporting. It supports formulas, charts, pivot tables, conditional formatting, and multiple worksheets in a single file.
XLSX was introduced with Microsoft Office 2007 as the successor to .xls, using XML-based storage for better compatibility and smaller file sizes.
