About JSON to YAML Converter
The JSON ⇄ YAML converter translates between the two most common configuration formats.
YAML is what you write by hand — Kubernetes manifests, GitHub Actions workflows, Docker Compose files, CI pipelines — because it is indentation-based and comment-friendly.
JSON is what machines emit and APIs speak.
This tool moves cleanly in both directions so you can paste an API response and get readable YAML, or paste a config and get strict JSON for a tool that demands it.
Conversion uses a battle-tested YAML parser, so anchors, multi-line strings, nested mappings and sequences all translate faithfully.
Invalid input produces a clear error rather than mangled output.
Like the rest of My Tools Garage, it runs entirely client-side — your configuration, which often contains secrets and infrastructure details, never leaves your browser.
FAQ
Does it preserve comments?
JSON has no comment syntax, so converting YAML → JSON drops comments. Converting JSON → YAML produces clean YAML without comments to add.
Is it safe for secrets in my config?
Yes. Conversion runs in your browser only; nothing is transmitted to any server.
