Best use cases

Common mistakes

Indentation is inconsistent

Fix: Use consistent spaces because YAML structure depends on indentation.

The YAML includes advanced syntax the simple parser does not support

Fix: Use clean key-value YAML with standard nesting and lists for predictable conversion.

The user expects comments to appear in JSON output

Fix: JSON does not support comments, so only the actual data can be converted.
