Data Shape-Shifter FAQ
What survives the CSV corner?
CSV is flat: arrays of uniform objects convert beautifully; nested structures JSON-stringify into cells (honest, if ugly). The triangle’s geometry, not the tool’s whim — deep data belongs in the JSON/YAML edge.
How does detection order work?
JSON parse first (strictest), CSV shape second (delimiters + header line), YAML last (most permissive). Ambiguous inputs resolve to the strictest passing parse, which is the least surprising rule we know.
