JSON to YAML

Convert JSON objects and API responses to YAML for Helm, Ansible, Kubernetes, Docker Compose, and CI/CD configs.

For this tool, processing runs locally in your browser and data is not sent to the server.

JSON to YAML is a free online converter that transforms valid JSON into YAML for Helm, Ansible, Kubernetes, Docker Compose, CI/CD, documentation, mock data, and dev configs. The tool validates JSON before conversion and preserves objects, arrays, strings, numbers, booleans, and null values. It runs entirely in your browser and does not send data to the server.

How to use

Paste a JSON object, API response, payload, mock data, or config into the JSON field.
Choose YAML settings: indent size, array style, quoting, and key sorting.
Click Convert or wait for the automatic result.
Copy the YAML and use it in Helm, Ansible, Kubernetes, Docker Compose, CI/CD, documentation, or dev configs.

More about this tool

JSON to YAML converts valid JSON into YAML for Helm, Ansible, Kubernetes, Docker Compose, CI/CD configs, documentation, mock data, and dev configs. The tool validates JSON via JSON.parse first, then preserves the structure of objects, arrays, strings, numbers, booleans, and null values in their YAML representation.

You can choose 2 or 4 space indentation, array style, quoting for string values, key sorting, and whether to preserve the original key order from the JSON.

All processing is done locally in the browser. Your data is not sent to the server.

Frequently Asked Questions

How do I convert JSON to YAML?

Paste valid JSON into the input field, choose output settings, and click Convert. The tool converts the JSON structure into YAML.

When is a JSON to YAML converter useful?

It is useful when a JSON object, API response, or mock data needs to be used in a YAML config, Helm values file, Ansible playbook, Kubernetes manifest, Docker Compose file, or CI/CD config.

Is JSON validated before conversion?

Yes. The tool first validates the JSON via JSON.parse. If the JSON has an error, YAML is not generated and an error message is shown.

Are data types preserved?

Yes. Objects, arrays, strings, numbers, booleans, and null values retain their types in the YAML output.

Can I choose the YAML indent size?

Yes. You can choose 2 or 4 spaces in the settings.

Will the YAML output include comments or anchors?

No. JSON does not contain comments, anchors, aliases, or custom tags, so the converter cannot reconstruct such YAML-specific constructs.

How is this different from YAML to JSON?

JSON to YAML converts JSON into YAML. YAML to JSON does the reverse: it parses YAML and outputs JSON.

Does the tool validate Kubernetes, Helm, or Ansible schemas?

No. The tool only converts the data format. Helm, Ansible, Kubernetes, or CI/CD schema correctness must be verified with dedicated validators.

Is my data sent to the server?

No. JSON is processed locally in the browser and is not sent to the server.

Do I need to register?

No. The tool works immediately without registration.
