How to use the YAML to JSON

YAML is popular for config files (Docker, Kubernetes, CI) while APIs speak JSON. This tool converts between them using a full YAML parser.

All parsing happens locally in your browser.

Does it support multi-document YAML?

It converts the first document; standard mappings, sequences and scalars are fully supported.

Is it private?

Yes — nothing is uploaded.

JSON Formatter & Viewer Paste JSON to beautify, validate and explore it in a live collapsible tree — with search, expand/collapse and JSONPath.
