What YAML features are supported?

Our converter supports YAML 1.2 features including nested objects, arrays, multi-line strings, comments (stripped in output), anchors, and most common YAML constructs.

Does it handle multi-document YAML?

Currently it converts the first document in a multi-document YAML file. Split your documents if you need to convert each separately.

Are YAML comments preserved?

Comments are not preserved since JSON doesn't support comments. Use our JSON to YAML converter if you need to add comments back.

Can I convert JSON back to YAML?

Yes! Use our JSON to YAML converter for the reverse operation.
