JSON to YAML Converter

Convert JSON to clean, properly-indented YAML using a real YAML serializer.

Paste JSON below - this tool parses it and serializes it as clean, properly-indented YAML.

For the reverse direction, see the YAML to JSON Converter.

How to Use It

  1. Paste valid JSON.
  2. Click Convert.
  3. Copy or download the resulting YAML.

Understanding the Result

JSON objects become YAML mappings, arrays become YAML sequences, and primitive types (strings, numbers, booleans, null) are preserved - the output uses standard block-style YAML formatting for readability.

Limitations

YAML supports some features JSON has no equivalent for (anchors/aliases, comments) - since the input is JSON, the output is always plain, comment-free YAML.
