What is YAML → CSV?
A YAML→CSV converter for lists of records, with the union of all keys used as headers so heterogeneous lists still convert.
How it works
The YAML parses with js-yaml, keys across rows are unioned into headers, and each row is written with RFC 4180 escaping via the shared CSV writer.
