Free tool
Paste any JSON and get clean, properly-indented YAML. Useful for converting API responses, configuration data, or any JSON into human-readable YAML format. Runs entirely in your browser. Need the reverse? Try our YAML to JSON converter.
Used when you click Download .yaml. The .yaml extension is added if you leave it off.
Paste some JSON to get started.
How it works
1. Paste your JSON
Drop in an API response, a config object, or any valid JSON. Click Load sample to see an example.
2. Converted to YAML
We parse the JSON and serialize it to clean, properly-indented YAML preserving all nesting and types.
3. Copy or download
Click Copy YAML for clipboard, or Download .yaml for a file. Everything happens locally.
Why use this converter
- Private by design. Your JSON never leaves your browser. Nothing uploaded, logged, or stored.
- Clean output. Two-space indentation, no anchors or references, properly quoted strings where needed.
- Preserves structure. Nested objects, arrays, booleans, numbers, and strings all convert correctly.
- Free forever. No signup, no rate limits, no paywall.
Need more than conversion?
If you find yourself shuffling config formats over and over because your team has no central place to capture configuration changes, you might want a proper intake queue. We are building one.
