YAML to JSON Converter
Convert basic YAML to pretty-printed JSON. Supports nested objects, lists, and common types.
Note: Only basic YAML is supported (key-value, nested objects, lists). Complex YAML features like anchors, tags, and multi-document are not supported.
Paste any YAML and convert it to clean, formatted JSON instantly. Useful when you have config files in YAML and need JSON for APIs, JavaScript, or tools that don't support YAML directly.
Features

How to Convert YAML to JSON

FAQ
Does it support multi-document YAML?▾
Single-document YAML is fully supported. Multi-document YAML (separated by ---) converts the first document.
What happens with YAML comments?▾
Comments are stripped in the JSON output since JSON doesn't support comments.
