FAQs
Is YAML a superset of JSON?
Yes - any valid JSON document is also valid YAML 1.2.
Will indentation matter in the output?
Yes - YAML is indentation-sensitive. The generator uses 2-space indent by default.
What about types like dates?
JSON has no date type, so dates go in as strings. YAML can preserve some ISO dates as native timestamps if both ends agree.
