About this tool
Convert JSON data to YAML format. Useful when reviewing API responses, cleaning config before commit, or sharing readable snippets in docs and PRs.
Paste a JSON object or array into Input. Click Convert to emit YAML in the Output pane. Example — Turn a service config into YAML: try `{"service":"api","port":8080,"debug":false}` and expect something like `service: api port: 8080 debug: false`.
YAML anchors, tags, and custom types are not generated — you get a straightforward dump. See also: YAML to JSON, YAML Formatter, and JSON Formatter. Runs in your browser — nothing you paste gets uploaded.
How to use
- Paste a JSON object or array into Input.
- Click Convert to emit YAML in the Output pane.
- Copy the YAML into a config file or CI workflow.
- Keep nesting shallow when possible — deeply nested JSON becomes hard-to-scan YAML.
Example
Turn a service config into YAML
Input
{"service":"api","port":8080,"debug":false}Output
service: api port: 8080 debug: false
Limitations
- YAML anchors, tags, and custom types are not generated — you get a straightforward dump.
- Numeric-looking strings stay strings in JSON but can look ambiguous in YAML; quote them in hand edits if needed.
- Binary or non-UTF-8 data is outside this converter’s scope.
