About this tool
Converts in both directions, paste JSON to get YAML, or flip the direction and paste YAML to get JSON. The output updates live, and parse errors tell you what's wrong rather than failing silently.
The usual use case: moving config between JSON-first tools and YAML-first ones like Kubernetes, GitHub Actions and CI pipelines. Conversion runs locally via js-yaml.
How it works
- Paste your input, or drop a text file onto the box.
- The output updates live as you type.
- Copy it to the clipboard, or download it as a file.
