Common questions
Does this preserve comments in my YAML?
No — comments aren’t part of the underlying data structure, so converting to JSON and back will not preserve them. This is true of any JSON/YAML converter, not a limitation specific to this one.
What happens if my input isn’t valid?
You’ll get a clear error explaining what’s wrong rather than a broken or partial conversion.
