Questions
Is my data uploaded?
No. Everything runs in your browser, so your data never leaves your device.
Are comments kept?
No. JSON has no comments, so YAML comments are dropped when converting to JSON.
Does it support anchors and aliases?
Yes. YAML anchors and aliases are expanded into plain JSON values.
