What the JSON to YAML Converter does
The JSON to YAML Converter rewrites JSON as YAML: indentation replaces braces, list items start with a dash, and most strings no longer need quotes. The data is the same; only the notation changes.
Strings that could be misread in YAML, such as yes, null or text containing a colon, are quoted automatically so they stay strings.
Key order is kept, nested objects become indented blocks, and arrays of objects become lists whose items start with a dash. Empty arrays and objects are written as [] and {}.
When to use it
- Writing Kubernetes manifests, Docker Compose files, GitHub Actions workflows or Ansible playbooks from JSON you already have.
- Making a long configuration easier to read and review.
- Converting an OpenAPI specification from JSON to the more common YAML form.
- Preparing values for a Helm chart or another YAML-based configuration from a JSON export.

Common questions about the JSON to YAML Converter
Is every JSON document valid YAML?
Yes. YAML 1.2 is a superset of JSON. Converting to block-style YAML makes it easier to read, but the data stays the same.
Can I add comments?
Yes, after converting. YAML supports comments that start with #. JSON has no comments, so the converter has none to carry over.
How do I go back to JSON?
Use the YAML to JSON Converter. Comments you added in YAML are dropped, because JSON cannot store them.
