  2. Choose the direction.
  3. Copy or download the result.

Questions

Are comments kept?

No. JSON has no comments, so YAML comments are dropped when converting.

Are my files uploaded?

No. The tool runs inside your browser, and the page is blocked from sending data anywhere. You can check by turning off your internet connection: it keeps working.
