Does the converter preserve types?

Yes — strings, numbers, booleans, nulls, arrays and nested objects all map to their native YAML equivalents.

Is YAML just a superset of JSON?

Practically, yes — every JSON document is valid YAML 1.2. Converting gives you the idiomatic block style that configs use, instead of JSON's braces.

JSON to YAML Converter

Valid JSON in, clean YAML out — instantly.

The view appears once there is JSON to show.

JSON → YAML for configs and pipelines

Kubernetes manifests, GitHub Actions, docker-compose, OpenAPI — modern infra speaks YAML. Paste JSON on the left and get spec-compliant YAML with 2-space indentation on the right, ready to drop into a config file.

Your input is validated first, so you never convert a payload that was silently broken. Everything runs in your browser — your JSON never leaves your device, so it is safe for API keys, customer records, and production payloads.
