Your CSV must have a header row with these columns (in any order):

Day of the Week — Full name (Monday, Tuesday…) or abbreviation (Mon, Tue…)
Start Time / End Time — 12-hour (9:00 AM) or 24-hour (09:00)
Recurring Shift Start Date — MM-DD-YYYY, MM/DD/YYYY, MM-DD-YY, MM/DD/YY, or month-name formats like Aug 26, 2026 (from your company profile setting). Required to place each row on the schedule.
Recurring Shift End Date — MM-DD-YYYY, MM/DD/YYYY, MM-DD-YY, MM/DD/YY, or month-name formats like Aug 26, 2026. If both start and end are present, the row is treated as recurring. If end is blank, a single shift is created.
Assigned To — Employee's full name, must match the staff list (case-insensitive)

Each row uses the first matching weekday on or after Recurring Shift Start Date. Recurring rows generate one shift per matching weekday through Recurring Shift End Date.
