Convert ODS to XLSX.
Convert an OpenDocument spreadsheet (.ods) to Excel .xlsx with formatting and formulas preserved by LibreOffice.
ODS to XLSX, for Excel compatibility
ODS is the OpenDocument spreadsheet — the native format of LibreOffice and OpenOffice, and a common choice in government and open-source setups. XLSX is Excel's format and the one most businesses and tools expect. Converting is what you do when a colleague or system needs the file in Excel rather than OpenDocument.
What carries across
The conversion is rendered by LibreOffice itself, so it's high fidelity: formulas keep working, every sheet comes through, and most cell formatting — number formats, borders, fills — is preserved rather than flattened to plain values.
A note on edge cases
The two formats aren't identical, so a handful of advanced features — certain spreadsheet functions, macros or very specific formatting — can shift slightly between them. Plain data and standard formulas convert cleanly; double-check anything unusual after opening in Excel.

ODS to XLSX
This converts tabular data from ODS to XLSX. Values, rows and columns carry over; formulas, charts and styling generally aren't carried across — what you get is the data, cleanly structured.
Common questions
Is it free?+
Yes — convert ODS to XLSX free. No signup, no watermark, no daily cap.
Is my data private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Will formulas and formatting survive?+
Yes — LibreOffice converts the document itself, so formulas, multiple sheets and most cell formatting carry across. Very app-specific features (certain functions or macros) can shift slightly.
