Frequently Asked Questions
Does this converter support nested structures?
Yes. Complex nested arrays, dictionaries, and mixed primitives convert with proper indentation.
Why does YAML not use tab characters?
The official YAML specification forbids tab characters for indentation because different text editors render tabs with varying column widths. Always use spaces.
Are comments preserved when converting from YAML to JSON?
Standard JSON does not support comments, so YAML comments are stripped during conversion to JSON.
