Why use this tool

  • Powered by js-yaml — round-trips through a real YAML emitter.
  • YAML is more readable for hand-edited configs (Kubernetes, GitHub Actions, Ansible).
  • Sort-keys mode produces diff-friendly output.
  • Pure client-side, your data stays private.

Frequently asked questions

Why are strings quoted sometimes and not other times?

js-yaml only quotes strings that would parse as a different type (numbers, booleans, dates) or contain special characters. Unquoted is preferred for readability.

Does this preserve order of keys?

Yes by default — JSON object order is preserved. Turn on Sort keys for alphabetical output.

Can it handle very deep nesting?

js-yaml has no fixed limit, but very deep structures (>100 levels) can run into JS engine recursion limits.
