Write Cells
Pick a tab to see its header row + first 100 data rows. Headers come from row 1.
Write to a specific range using A1 notation, e.g. tab name clients + range B5 for a single cell, or B5:D5 for a row span.
Values must be entered as a JSON 2D array — one row per array — even for a single cell: [["new value"]].
