GUIDE & CONTEXT

About this tool

Move structured data between JSON APIs and YAML-based configuration files. The converter handles data rather than source formatting, so comments and original spacing do not survive a round trip. YAML values without a JSON representation may be rejected instead of silently inventing a conversion.

How to use it

  1. Choose YAML to JSON or JSON to YAML.
  2. Paste one complete data document and check its nesting.
  3. Convert, inspect the result and copy it to your destination.
Example

YAML name: Ling with a second line enabled: true converts to {"name":"Ling","enabled":true}.
