Options
Remove Comments

Parse path drops comments; whitespace path keeps them
YAML conversion helpers
Use JSON → YAML, YAML → JSON, YAML → XML or YAML → CSV for format conversion.
FAQ — Beautify YAML
Beautification
Why did my comments disappear?
js-yaml parse drops # comments — documented limitation (TD-021).
Minify instead?
Use YAML minifier with removeComments: false to keep # lines.
