What is YAML → JSON?
The YAML to JSON converter transforms YAML documents into JSON for use in tools and workflows that require JSON input.
How it works
We use js-yaml to parse the YAML input, then serialize the result as formatted JSON.
- Paste YAML. Drop a .yaml file or paste YAML text.
- Convert. Conversion happens automatically as you type.
- Copy or download. Copy the JSON or download as .json.
Examples
Simple mapping
name: Alice age: 30 becomes {"name":"Alice","age":30}.
Common mistakes
Tab indentation
YAML uses spaces, not tabs. js-yaml returns an error for tabs.
Alternatives
JSON to YAML
The reverse direction.
