CSV and TSV need a header row. JSON needs an array of flat objects. Up to 100 columns and 200,000 cells; output up to 10 MB. Spreadsheet formulas are escaped on export.

Nested JSON is rejected so no structure is silently lost. Values from CSV and TSV remain strings in JSON. Formula-like cells are prefixed with an apostrophe in CSV and TSV output.
