About YAML ↔ JSON Converter

YAML ↔ JSON Converter swaps between the two most common config formats in both directions. Paste YAML to get JSON, or paste JSON to get YAML — useful for migrating Kubernetes manifests, GitHub Actions workflows, OpenAPI specs, and any config that's been chosen to live in one format but you need to read in the other. Powered by the 'yaml' library. Runs entirely in your browser.
