About the YAML to JSON
Many tools accept YAML for human authoring but require JSON internally. This converter parses YAML with a robust, spec-compliant parser and emits clean, indented JSON. It handles anchors, lists, nested maps and all scalar types.
Everything runs in your browser, so private configuration never leaves your machine. Use it to feed YAML config into a JSON-only API, to inspect a manifest as JSON, or as the inverse of the JSON to YAML tool.
