Values are typed like in Google Sheets: 12.5 becomes a number, 2026-10-18 a date, TRUE a boolean. Cells that already hold text stay text. Drag a column header to move it, drag its right edge to resize (double-click the edge to fit the content); this only changes your view, not the sheet. Changes are checked against the latest data before saving, and every save is recorded in the app's audit log.
