Turn YAML into JSON

Paste a block-style YAML snippet — a GitHub Actions step, a Kubernetes manifest, or a docker-compose fragment — and get the equivalent pretty-printed JSON with 2-space indentation. This is the reverse of the JSON to YAML tool, so formatting JSON to YAML and back recovers the original value.

Supported: block mappings (key: value) and sequences (- item) nested by consistent indentation; plain, single-quoted, and double-quoted strings; integers, floats, true/false, and null/~; empty flow collections {} and []; and # comments.

Not supported (rejected with an inline error): anchors and aliases (&, *), tags (!!type), multi-document streams (--- / ...), block scalars (|, >), and non-empty flow collections such as {a: 1} or [1, 2].
