Convert CSV to ODS
Turn a CSV file into an OpenDocument Spreadsheet (.ods) — LibreOffice's own format.
How it works
- Drag and drop your CSV (.csv) file below.
- Click Convert to download the spreadsheet.
What this tool does to your file
The CSV becomes an OpenDocument Spreadsheet, LibreOffice’s own format, with each value in its own cell. The delimiter is sniffed rather than assumed: comma wins ties, but semicolon is accepted, because that is what Excel writes in every locale whose decimal separator is a comma — Hungarian included — and treating those files as comma-delimited would produce a single column holding each whole row as text. Numeric coercion is narrow on purpose: only a plain, optionally negative decimal becomes a number, so leading-zero codes and long identifiers survive as text rather than being reformatted into something else. The file is rejected if it turns out to be a binary file with a .csv extension. CSV uploads are capped at 10 MB whatever your tier, because a dense CSV expands into far more memory as cells than it occupied as bytes.
What happens to your files
- No account needed — Every tool works as a guest. Signing in raises the limits and keeps your files together, but nothing asks you to register before you get a result.
- It runs in your browser — There is nothing to install and nothing to keep up to date. Files travel to our servers over an encrypted connection, and come back the same way.
- Your files stay yours — Files and results stay in your account until you delete them. Files from a guest session that is never linked to an account are removed automatically after a period of inactivity.
- Size limits, stated up front — Up to 10 MB per file as a guest, and up to 25 MB signed in. You see the limit before you upload, not after.
