Questions
Are my comments kept?
Yes. Unlike converting to JSON and back, this formatter keeps comments, anchors, aliases and document separators (---).
Why is my YAML invalid?
The usual causes are tabs used for indentation, a missing space after a colon, and list items at the wrong indent level. The error shows the line and column to look at.
Is my config uploaded?
No. Everything runs in your browser, so secrets in your config never leave your device.
