Questions & answers

Frequently asked

Will strings that look like dates get quoted?

Yes. Strings that could be misinterpreted (dates, booleans like 'yes'/'no') are quoted to preserve their type.

Does it add YAML document markers (---)?

No by default, but the output is valid YAML and can be prepended with --- if needed for multi-document streams.
