How it works

β–  What is JSON? JSON (JavaScript Object Notation) represents key-value pairs, arrays, and nested objects as text. It is commonly used for API requests/responses and data exchange. β–  What is YAML? YAML (YAML Ain't Markup Language) is a human-readable config format that uses indentation for hierarchy. Widely used in Kubernetes manifests, CI/CD (e.g. GitHub Actions), Docker Compose, etc. β–  How conversion works The tool parses the JSON into an object and serializes it to indented YAML. All processing runs in the browser.
