About this tool

Paste a YAML document to get its JSON equivalent, or paste JSON to get back readable YAML — useful when moving config between tools that expect one format or the other (Kubernetes manifests, CI configs, API payloads).

Conversion runs entirely in your browser using the same YAML parser many Node.js tools rely on, so nested objects, arrays, and scalars round-trip correctly.

Both — switch between "YAML → JSON" and "JSON → YAML" with the toggle above the input.
