JSON to YAML Converter

JSON is for machines; YAML is for humans editing config files. If you're hand-writing Kubernetes manifests, Docker Compose files, GitHub Actions workflows or Ansible playbooks, converting your JSON to YAML gives you something you can actually read and maintain — no quote balancing, no trailing-comma anxiety.

Paste your JSON above and get cleanly indented YAML out (2 or 4 spaces, your call). The conversion runs entirely in your browser, so secrets in your configs stay on your machine.

FAQ

Is every JSON document valid YAML?

Yes — YAML 1.2 is a superset of JSON, so JSON parses as YAML as-is. This tool goes further and rewrites it in idiomatic, human-friendly block style.

Are anchors or comments generated?

No. Anchors and comments can't be derived from JSON, since JSON supports neither. The output is plain, explicit YAML.

Is it safe to paste configs with credentials?

Yes. Nothing is uploaded — parsing and conversion happen locally in your browser.
