JSON to YAML

What is JSON to YAML conversion?

JSON and YAML represent the same data model — both support objects, arrays, strings, numbers, booleans, and null — but YAML's syntax is far more human-readable. YAML omits quotes and braces in most cases, uses indentation for structure, and supports inline comments. Converting JSON to YAML is a common step when moving data from an API response into a Kubernetes manifest, Docker Compose file, or GitHub Actions workflow.

How to convert JSON to YAML

1. Paste your JSON into the left pane, or drop a .json file.
2. The YAML output appears instantly on the right — no button to click.
3. Copy the YAML with one click, or download it as a .yaml file.
4. Need to go the other way? Use our YAML to JSON converter.

Why convert JSON to YAML for Kubernetes and CI/CD?

Kubernetes, Helm, GitHub Actions, and most CI/CD systems use YAML for configuration because it is easier to write and review than JSON — no trailing-comma issues, no need to quote every key, and you can add comments to explain configuration decisions. When an API returns JSON that you need to adapt into a Kubernetes deployment manifest, this converter saves the manual reformatting step.

Privacy when converting configuration data

Configuration JSON frequently contains environment variables, API keys, database connection strings, and service credentials. This converter processes everything locally in your browser using theyaml npm package — none of your config data is ever sent to a server.
