Paste rows, one per line: name, username, password, store, rate, barcode, role (barcode and role optional; role = employee or manager). For a manager covering two stores write the store as e.g. 468;641. Header lines are ignored.
One punch per line: username, clock in, clock out — times as YYYY-MM-DD HH:MM (store time). Re-importing the same lines is safe (duplicates are skipped).
