Deterministic mapping

How the JSON conversion works

Quoted tabs, doubled quotes and multiline quoted fields are parsed using the same proven delimited-text rules as CSV.

Honest limitations

Tabular formats cannot preserve every source detail

Cells remain strings unless primitive inference is enabled. Duplicate or blank headers and inconsistent rows produce diagnostics.
