Frequently asked questions

Are comments preserved when converting YAML to JSON?

No. JSON has no concept of comments, so YAML comments are dropped during conversion. Values and structure are fully preserved.

Does indentation matter in my YAML input?

Yes. YAML uses indentation to express structure, so consistent spacing is required for it to parse. The converter reports errors if the YAML is malformed.

Can it handle multi-document YAML?

It focuses on converting a document's data structure between formats; provide one document at a time for predictable results.
