Convert XLSX to ODS
Drop your XLSX, get a ODS. The file is processed in memory, returned with its SHA-256 fingerprint, then forgotten — nothing is kept on our servers.

What this conversion changes
Going from XLSX to ODS is not neutral. What the service can tell you before you drop anything:
- XLSX and ODS carry the same kind of information: this conversion asks for no particular trade-off.
The same conversion, in one line
The browser and your backend call the same endpoint, and get the same response.

Is converting XLSX to ODS free?
Yes, in the browser and without an account. The API has a free quota; a refusal is never counted.
Are my files kept?
No. The file is processed in memory then forgotten. Logs carry only its SHA-256 fingerprint and its size — never its name or its content.
What happens if my file is not really a XLSX?
The format is read from the file’s bytes, never from its extension. An unrecognised file gets an explained refusal with a stable code — and that refusal is not billed.
