Options

Remove Comments

When true, parse+dump removes # comments. When false, whitespace-only minify preserves # lines.

Parse path drops comments; whitespace path keeps them

Indent Width

2 or 4 spaces for beautify, unminify, and parse-based minify.

String Quotes

Minimal or double-always quoting on dump.

YAML conversion helpers

Use JSON → YAML, YAML → JSON, YAML → XML or YAML → CSV for format conversion.

FAQ — Minify YAML

Minification

Are # comments preserved?

Only when removeComments is false (whitespace path). Parse-based minify removes them.

Beautify YAML?

See YAML beautifier — comments cannot survive parse.
