JSON to YAML
JSON to YAML turns JSON into YAML, the human-friendly markup used by Kubernetes, CI pipelines and many configuration systems. It preserves the exact data structure while improving readability.
Key Features
- Lossless JSON to YAML conversion
- Configurable indentation
- Preserves types (numbers, booleans, null)
- Copy or download the YAML
- Local conversion
Use Cases
- Author a Kubernetes manifest from API data
- Write a CI config from a JSON spec
- Make a config file easier to review
- Migrate between formats safely
How to Use
- Paste your JSON
- Set the desired indentation
- Convert to YAML
- Copy or download the result
Practical Tips
- YAML is indentation-sensitive; keep it consistent
- Quote strings that look like numbers if needed
- Validate the YAML in its target system after conversion
FAQ
- Is the conversion lossless?
- Yes, the data structure is preserved exactly.
- Why does my number become a string?
- Only if the source quoted it; ensure numeric types are unquoted in JSON.
