Supported formats
This tool accepts .xlsx, .xls. Free, up to 10MB and the first 50,000 rows. We work out the encoding and the separator from the file itself, so a semicolon-separated export or one saved in a non-UTF-8 encoding opens correctly rather than as a single column of nonsense.
Questions
- What happens to formulas?
- A CSV cannot hold a formula, so we write the value each one last calculated — which is what you see on screen.
- Will the accented characters survive?
- Yes. We write UTF-8 with a byte-order mark, which is what makes Excel on Windows read it correctly instead of falling back to the local codepage.
- What happens to my file?
- It is uploaded over an encrypted connection, processed, and deleted automatically - within 24 hours for anonymous use. We never use anyone’s spreadsheet data to train models. You can delete a job and its files at any time from the job page.
Want the data cleaned up before you export it?
The full app handles jobs that need several steps across several files, and can save the whole thing so next month takes two clicks.
