Common Practical Use Cases
- Kubernetes work: turn a manifest into JSON so you can query it with jq while debugging a deployment.
- CI pipelines: convert a JSON config export into YAML for a GitHub Actions or GitLab workflow file.
- API documentation: move an OpenAPI description between the YAML and JSON forms a tool expects.
- Config review: reformat a hand-edited YAML file through JSON to confirm it parses as you intended.
