YAML ↔ JSON

Switch between YAML and JSON without losing comments or structure.

Interactive
The yaml ↔ json workspace is being lifted from the original build.

The same logic you already rely on, dressed in the new editorial layout. Until it lands here, the notes below cover what the tool does and when it earns its keep.

Translate configuration files or API manifests between YAML and JSON. The converter preserves indentation, normalizes keys, and points out syntax problems before they make it into production.

Round-trip conversions

Paste YAML to generate formatted JSON or go the opposite direction. The tool handles nested objects, arrays, and multi-line strings gracefully.

Safe editing experience

Validation runs locally and highlights structural issues. Perfect for working on Kubernetes manifests, GitHub Actions, or serverless configs.

When it earns its keep

  • Convert CloudFormation templates between YAML and JSON
  • Share readable JSON versions of YAML configs with teammates
  • Prepare API payloads for tooling that only speaks one format

Questions people ask

Are comments preserved?

YAML comments are kept when converting to YAML. JSON does not support comments, so they are removed when converting to JSON.

Does it handle anchors?

Yes, YAML anchors and aliases are resolved before the conversion takes place.
