How to convert ODS to CSV
- Choose or drop your ODS files. You can add several at once.
- Check that “To” is set to CSV.
- Press “Convert to CSV” and download the results — or all of them as one ZIP.
ODS vs CSV
ODS — OpenDocument spreadsheet. ODS is the open spreadsheet format used by LibreOffice and OpenOffice. Excel and Google Sheets can open it too.
CSV — Comma-separated values. CSV is plain text with one row per line and values separated by commas. Almost every app can import it, but it holds one table only — no formatting, formulas or multiple sheets.
Convert ODS to CSV when you need a file for importing data into databases, CRMs and other apps. ODS is better suited to LibreOffice users and open-standard requirements.
FAQ
5Are my files uploaded anywhere?
No. The conversion runs in your browser using your own device’s processor. Your files are never sent to a server, so nobody — including us — can see them. You can even disconnect from the internet after the page loads.
Will I lose quality?
Values are exported as plain text with a UTF-8 byte-order mark so Excel shows accented characters correctly. Formatting and formulas are not kept (CSV cannot store them); formulas are exported as their results. A workbook with several sheets becomes one CSV per sheet.
Is there a file size or daily limit?
No limits, and no sign-up. Because nothing is uploaded, we don’t pay for your conversions and have no reason to cap them. Very large files are limited only by your device’s memory.
Can I convert many ODS files at once?
Yes. Add as many files as you like; each is converted to CSV, and “Download all” saves them together as a ZIP.
Does it work on iPhone and Android?
Yes. It works in any modern browser — Safari, Chrome, Firefox or Edge — on phones, tablets and computers. Older or low-memory phones may be slower with very large files.
