What is YAML ↔ JSON?

YAML (YAML Ain't Markup Language) and JSON are both data serialization formats. YAML uses indentation for structure and is human-friendly, while JSON uses braces and brackets. This tool converts between the two formats instantly.

1. Select conversion direction (YAML→JSON or JSON→YAML). 2. Paste your data in the input area. 3. Click 'Convert'. 4. Copy or download the result.

Common Errors

YAML is indent-sensitive — mixing tabs and spaces causes errors. JSON requires double quotes for strings and keys. Ensure proper nesting in both formats.
