Turn JSON into clean block-style YAML with proper indentation — ready to drop into a Kubernetes manifest, CI pipeline or Compose file.
JSON is a fine wire format and a poor configuration language: no comments, mandatory quoting, and punctuation noise that makes diffs harder to read. YAML exists because humans edit these files by hand and review them in pull requests.
Comments are the main thing YAML gives you that JSON never had — the converter cannot invent them, so plan to add explanations after converting. Key order is preserved, but any formatting intent in the original JSON is not.
Strings that look like other types need quotes to survive: version numbers ("1.10"), leading-zero identifiers, yes/no, and anything containing a colon followed by a space. The emitter adds these quotes automatically — do not remove them by hand.
Reverse direction: YAML to JSON. Validating first helps: JSON formatter and validator.
It is emitted in block style with two-space indentation and wrapped at 100 columns — the conventional layout for Kubernetes manifests and CI configuration.
No. Anchors are disabled deliberately: they make files shorter but much harder to read and to diff, and many tools handle them poorly.
No. Conversion runs in your browser, so payloads containing tokens or customer data stay on your machine.
Strict JSON forbids trailing commas, single quotes and comments. Run it through the JSON formatter first — it reports the exact position of the problem.
Yes. The YAML emitter adds quotes where a plain value could be interpreted as another type, including leading-zero identifiers and boolean-like words. Removing those quotes by hand can change the data when another parser reads it.
