About the YAML ↔ JSON converter
Convert JSON to YAML or YAML to JSON in your browser. JSON output is always full and standards-compliant; YAML support covers a practical subset for configs and API payloads.
How it works
JSON → YAML walks the parsed value and emits indented key-value maps and dash lists. YAML → JSON uses a lightweight parser tuned for common config shapes, then serializes with JSON.stringify.
YAML limitations
This is not a full YAML 1.2 implementation. Supported: nested maps, dash lists, block scalars (| and >), comments, and basic scalars. Not supported: anchors and aliases, tags, multi-document streams, complex keys, or every edge case in the spec. For production-critical YAML, validate with a dedicated parser.
Limits
Input up to 2,000,000 characters. Very large documents may take a moment on slower devices.
Privacy first
Conversion runs locally in your browser. Nothing you paste is sent to a Dockzio server.
