What this tool does
The tool first uses JSON.parse to strictly verify the input, and then passes it to js-yaml for serialization. This not only gives clear JSON syntax errors, but also reliably handles YAML quotes, array indentation, and easily ambiguous strings.
- Objects, arrays, strings, numbers, Boolean values, and null are all explicitly represented.
- Disables circular reference output; JSON itself does not contain reference cycles.
- The results can be saved as result.yaml.
How to use it
- Paste standard JSON.
- Click "Convert to YAML".
- Check array indentation versus quoted strings.
- Copy the results or download the YAML file.
Common uses
- Migrate application configuration to YAML.
- Generate an initial readable version of the CI/CD configuration.
- Compare JSON and YAML hierarchical expressions.
JSON → YAML Features
Convert standard JSON to human-readable YAML, correctly handling objects, arrays, and various scalar types. It is suitable for daily development, debugging, data sorting and code optimization scenarios. The processing results can be directly viewed, copied or downloaded.
FAQ
Will I still get the exact same text after conversion?
The format text will differ, but the values of objects, arrays, and scalars should remain consistent; the key order usually retains the parsed order.
Why are strings sometimes automatically quoted?
Generators quote strings that might be misread as numbers, Boolean values, or special syntax to preserve the original type.
How is null represented in JSON?
The null representation of YAML is output instead of a normal string.
