LibreOffice Calc / OpenDocument Spreadsheet
ODS to Excel converts LibreOffice Calc and OpenDocument Spreadsheet (.ods) files into Microsoft Excel (.xlsx) format. Useful when you need to share spreadsheets with users who don't have LibreOffice.
Drop your .ods file. SheetJS reads the OpenDocument Spreadsheet format natively, extracting all sheets and cell data, then writes it as a modern .xlsx file — entirely in your browser. Nothing is uploaded.
Upload your ODS file
Drop an OpenDocument Spreadsheet (.ods) file from LibreOffice or Google Sheets export onto the upload zone.
Convert
Click "Convert to Excel". The ODS structure — sheets, formulas, and cell formatting — is mapped to XLSX format.
Download the XLSX
Save the .xlsx file and open it in Microsoft Excel or any Excel-compatible editor.
Review
Check formulas and formatting after conversion, as some ODS-specific features may need minor adjustment in Excel.
Cross-App Sharing
Convert LibreOffice Calc spreadsheets to XLSX before sharing with colleagues or clients who use Microsoft Excel.
Business Reports
Convert ODS financial reports to Excel format for compatibility with corporate dashboards and reporting tools.
Data Analysis
Open ODS exports from accounting or ERP software in Excel for further analysis using PivotTables and charts.
Mixed-OS Teams
Teams working across Linux (LibreOffice) and Windows (Excel) can share spreadsheets seamlessly after ODS to XLSX conversion.
Cloud Uploads
Upload spreadsheets to Google Sheets, OneDrive, or SharePoint, which work best with XLSX rather than ODS.
Legacy System Exports
Many government and open-source platforms export data as ODS — convert to XLSX for use in standard Excel workflows.
Browser-Only Processing
SheetJS reads your ODS file entirely in the browser using WebAssembly — no server, no upload, complete privacy.
All Sheets Preserved
Every worksheet in the ODS workbook is transferred to the output XLSX with its name and structure intact.
Formula Compatibility
Standard spreadsheet formulas are converted and remain functional in Excel after the conversion.
XLSX Compatibility
The output is a standard .xlsx file that opens correctly in Excel 2007 and later, Google Sheets, and LibreOffice Calc.
No File Size Limit
There is no hard file size restriction, so large ODS spreadsheets with many rows can be converted without issue.
