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.
