Is YAML a superset of JSON?

Yes. Valid JSON is technically valid YAML, but YAML extends JSON with features like comments, anchors, and multi-line strings.

How is indentation handled?

YAML uses spaces (not tabs) for indentation. The converter typically uses 2-space indentation by default.

Are JSON null values preserved?

Yes. JSON null converts to YAML null (or the tilde ~ shorthand).
