Frequently Asked Questions
- Why does conversion fail on my YAML?
- Tabs, inconsistent indentation, or ambiguous anchors often break parsers. Validate spacing and try a smaller excerpt to isolate the first error line.
- Multi-document YAML?
- Support depends on the engine. If you rely on --- separators, confirm whether the tool processes one document at a time or merges according to its UI.
