Common questions

Frequently asked questions

Does this handle YAML anchors and aliases?
Standard anchors (&) and aliases (*) are resolved and expanded into their referenced values in the JSON output.
What if my YAML has a syntax error?
The parser reports the approximate line where indentation or syntax breaks, so you can fix it and retry.
