About YAML to CSV Converter
The YAML to CSV converter parses a YAML sequence of flat mappings using js-yaml, then serialises the result to CSV using csv-stringify. Column headers are derived from the first mapping's keys. The CSV output panel shows a sortable table preview. Both editors are live — swap direction to CSV→YAML with one click.

Frequently Asked Questions
QDoes the YAML input need to be a sequence (array)?
Yes — the root YAML value must be a sequence (list) of flat mappings. Each mapping becomes one CSV row.
QIs my data sent to a server?
No. All conversion runs in a Web Worker inside your browser.
