JSON ↔ YAML Converter

Convert JSON to YAML and YAML to JSON

Teams mix JSON and YAML every day: GitHub Actions, Docker Compose, Kubernetes and Laravel config exports. Converting between the two formats without a local CLI speeds up reviews.

Edit either side. The converter uses js-yaml in the browser. YAML comments are dropped when you convert to JSON because JSON has no comment syntax. Nested maps, lists and scalars survive the round trip.

Use this when you want a Compose file from a JSON blob, or when an API example should become a Helm values snippet.
