How it works
The YAML is parsed with js-yaml and written back with consistent indentation. Multi-document files (separated by ---) are supported. Note that comments are not preserved — YAML parsers don't keep them.
FAQ
Where did my comments go?
YAML comments aren't part of the data, so they're lost when re-formatting. Keep a copy if you need them.
