Frequently asked questions

Why does conversion fail?

The input isn't valid YAML or JSON — the parser's exact error message is shown to help you find the issue.

Does this support CSV too?

No — CSV only maps cleanly to a flat list of same-shaped records, so it's kept as a separate, more limited tool rather than bundled here.
