Details

The important questions, plus the nearby routes users usually need next.
An array of objects, one per data row, with keys taken from the header row. A sheet with columns Name and Email becomes [{"Name": "...", "Email": "..."}, ...].
No — JSON holds data, not presentation. Formula cells export their computed values, and styling like colors and borders is discarded.
Each worksheet is converted as its own dataset rather than being merged, since sheets usually hold different tables. Convert each sheet you need.
