FAQ

Frequently asked questions

Are my files uploaded?

No. The conversion runs inside your browser using WebAssembly, so your files never leave your device. Nothing is sent to our servers.

What about formulas and formatting?

Values are converted. Formulas are exported as their calculated results; cell colours and charts aren't kept in CSV, JSON or Markdown.

Is it free?

Yes. The free plan converts up to 3 files at a time, up to 50 MB each. Note05 Pro ($5/month) removes ads and raises the limits to 100 files and 2 GB per file.
