## Key points

- Browser-based conversion can avoid uploading files.
- Adobe says it deletes files unless users sign in to save.
- Check privacy claims with a sample file and offline test.

## Summary

The article distinguishes spreadsheet converters that process files in a browser from services that upload them to a server, and from editors that encrypt data end to end. It says these options offer different protections, so users should match the tool to what they mean by privacy.

It cites browser-based CSV and Excel converters that claim files never leave the device, Adobe Acrobat’s online Excel-to-PDF service, and encrypted spreadsheet editors Proton Sheets and CryptPad. The vendor claims were not independently tested; the article suggests checking network activity or trying a tool offline with a sample file, and warns that features and policies can change.
