Free CSV to ODS converter

Why convert CSV to ODS?

People convert CSV to ODS because a CSV is only text with commas in it, holding no formulas, no formatting and no second sheet, while ODS is an open standard that LibreOffice and Google Sheets handle natively.

How to convert CSV to ODS

1. Choose your CSV file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .ods. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .csv file?

CSV is a table written as plain text: one row per line, values separated by commas. Every spreadsheet, database and programming language on earth can read and write it, which is why it remains the default way to move data between systems — at the cost of storing no formatting, no formulas and no idea what a date is.

What is a .ods file?

ODS is the open spreadsheet standard used by LibreOffice and OpenOffice Calc. It holds the same sheets, formatting and formulas as XLSX, and Excel can open one, making it a good neutral choice when you do not want to require Microsoft Office.

What to expect from this conversion

Cell values are carried across exactly as they appear. Formulas become their calculated results, and formats that hold only one table — CSV and TSV — take the first sheet of a multi-sheet workbook. Delimiters and quoting are detected automatically, including fields that contain commas.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your CSV file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about CSV to ODS

Is this CSV to ODS converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my CSV file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

Can I convert CSV to ODS online without downloading software?

Yes. This is an online CSV to ODS converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

Cell values are carried across exactly as they appear. Formulas become their calculated results, and formats that hold only one table — CSV and TSV — take the first sheet of a multi-sheet workbook. Delimiters and quoting are detected automatically, including fields that contain commas.

Can I convert several CSV files at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Can I convert CSV to ODS without Python or a script?

Yes — that is what this page is for. Python does the same job well if you already have it set up and thousands of files to process; for one file, or a handful, the browser is faster than installing anything.

Should I keep the original CSV file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that a CSV is only text with commas in it, holding no formulas, no formatting and no second sheet.
