JSON to YAML Converter
Render JSON as clean, human-readable YAML.
Objects become nested maps and arrays become - lists. Strings that could be read as numbers, booleans or dates are quoted so the YAML round-trips back to the same types.
How to use the JSON to YAML tool
- Enter your json to yaml in the fields above.
- Adjust any slider or type an exact number — the answer updates as you go.
- Copy the result and close the tab. Nothing you entered was sent anywhere.
About the JSON to YAML tool

The reverse of YAML to JSON, useful for turning a config payload into something you can paste into a Dockerfile, a CI workflow or a Kubernetes manifest.
