JSON to YAML Converter — Both Directions, Free

Convert between JSON and YAML in either direction instantly, preserving nested structure and data types — useful for translating a config file between formats, since many tools (Docker Compose, Kubernetes, CI pipelines) expect YAML while APIs typically speak JSON.

How to use JSON <> YAML

1. Paste your JSON or YAML.
2. Pick the conversion direction.
3. Copy the converted result.

Frequently asked questions

Are data types preserved correctly?

Yes — numbers, booleans, null and strings convert to their correct equivalent type in the target format rather than becoming generic strings.

Does it handle YAML-specific features like anchors and aliases?

Standard YAML anchors and aliases are resolved during conversion to JSON, since JSON has no equivalent reference mechanism — the resolved (expanded) values appear in the JSON output.

Is my data uploaded anywhere?

No. Conversion runs entirely in your browser.
