Convert YAML configuration into JSON — useful when a tool or API expects JSON but your config is written in the more human-friendly YAML.

How it works

The parser handles the standard configuration subset: maps, lists, and scalars. Obscure advanced YAML features like anchors are not supported.

While humans prefer YAML, many legacy APIs and strict programmatic parsers will only accept raw JSON data.

The tool will report a syntax error. YAML relies entirely on strict indentation, so ensure your spaces are perfectly aligned.
