About this tool
This page opens the data converter with JSON as the source and YAML as the target already selected — paste your JSON, run it and copy the YAML.
JSON to YAML turns curly-brace payloads into indentation-based markup that is far easier for humans to read and edit — the go-to move when preparing Kubernetes manifests, CI pipelines, docker-compose files or app configs from an existing JSON structure.
The full tool also converts XML and CSV in every direction and can generate TypeScript types — and every conversion runs locally in your browser, so your data never touches a server.
Example. The JSON text {"name":"Ada"} becomes the YAML line name: "Ada".
Limit. The YAML parser only understands indented key lines and dashes, so anchors, multiline block scalars, and tags are rejected.
