YAML to JSON Converter

Conversion uses js-yaml’s default schema, which parses data only and never executes code. Under YAML 1.2 rules no, on and off stay strings rather than turning into booleans the way YAML 1.1 parsers treat them. A multi-document YAML stream separated by --- becomes a JSON array, one entry per document. Anything JSON cannot express — dates, custom tags, non-string keys — is reported rather than silently dropped.
