How to use this tool
Start with simple key:value mappings or lists and inspect types and nesting. Validate anchors, aliases, block scalars and complex flow syntax with a complete YAML implementation.
Results and examples
name: Alice and enabled: true produce an object with a string name and Boolean enabled. Compare the output with the source and check whether date-looking values remain strings.
Worked example

Limitations
- Every YAML tag, alias, schema and multi-document stream is not supported.
- Complex syntax may silently become different text, so do not apply production configuration unchecked.
