Frequently Asked Questions
What YAML features are supported?
The converter supports all standard YAML features including maps, lists, strings, numbers, booleans, nulls, multiline strings, anchors, and aliases.
Will my complex YAML structure convert correctly?
Yes. The converter handles nested structures, lists of objects, comments (which are stripped), and all YAML syntax. If there's a syntax error, you'll get a clear error message.
Are YAML comments preserved?
No. Comments are not part of the data structure, so they are not included in the JSON output.
