Convert between JSON and YAML
JSON and YAML describe the same kind of structured data in different styles — JSON with braces and brackets, YAML with indentation. Configuration files increasingly use YAML because it's easier to read, while APIs speak JSON. This converter translates cleanly in both directions, so you can move a config or payload between the two without rewriting it by hand.
How to use it
- Paste JSON to get YAML, or YAML to get JSON.
- The conversion runs as you type; copy the result.
- Check the output in context, since indentation carries meaning in YAML.
Where it is useful
- Turning an API's JSON into a readable YAML config.
- Converting a YAML file into JSON for a tool that needs it.
- Comparing the same data in whichever form is clearer to you.
Questions people ask
Why does YAML care about spaces? Indentation defines structure in YAML, so levels must line up — tabs and inconsistent spacing are common sources of errors.
Is my data uploaded? No — the conversion happens in your browser.
