About JSON → YAML
Turn a JSON document into equivalent YAML — useful when moving an API response into a Kubernetes manifest, a CI pipeline or any config file that reads better as YAML.
How the output is shaped
Long values are never wrapped, so URLs and tokens stay on one line and remain copy-pasteable. Repeated objects are written out in full rather than as YAML anchors and aliases, because most config parsers handle plain YAML more predictably.
Frequently asked questions
- Is every JSON document valid YAML already?
- Effectively yes — YAML 1.2 is a superset of JSON, so a JSON file usually parses as YAML. Converting is about readability, not compatibility.
- What happens to null values?
- A JSON null becomes an empty YAML value, which YAML parsers read back as null. Round-tripping through this tool and back preserves it.
