Converting ODS to TOML gives you the same content in a different container. It runs in your browser: nothing is uploaded, there is no queue and no size limit.
What changes when you convert ODS to TOML
- Both formats are lossless: nothing in the picture or sound changes, only the container and the compression.
- Each row becomes one record with the header row as keys. Numbers stay numbers, empty cells become null.
When to convert, and when not to
Convert to TOML for project configuration. Minimal configuration format. Rust, Python and Cloudflare use it.
Keep ODS for LibreOffice users. LibreOffice's spreadsheet format.
How to convert ODS to TOML
- Drop your ODS file on the converter above, or click to choose. Several at once is fine.
- Check the options if you need them: sheet name (blank = first).
- Click Convert, then Download. Nothing was sent anywhere, your browser did the work.
Questions
Is my ODS file uploaded?
No. The conversion runs in your browser with WebAssembly. There is no upload endpoint on this site. You can open your browser's Network tab, or go offline after the page loads, and it still works.
Is there a file size limit?
No fixed one. The limit is your device's memory: a large data file on a phone is slower than on a laptop, but nothing is rejected for being big.
Is it free?
Yes, without an account, without a daily cap and without a watermark. Your device does the computing, so there is no server bill to pass on.
Will the quality drop?
No. TOML is lossless: the data content is stored exactly.
Can I convert several files at once?
Yes. Drop them all; each is converted in turn and you can download them one by one or as a single ZIP.
Which engine does the conversion?
Data engine (SheetJS, js-yaml, fast-xml-parser, smol-toml), compiled to WebAssembly and running in your browser. First use downloads about 0.9 MB, cached afterwards.
