Then, select the cells that contain the letters and use the fill handle to copy the entire alphabet as many times as required.
Fortunately, there are three workarounds for forcing the fill handle to produce the list. For instance, if you enter A, B, and C, in adjacent cells and then use the fill handle to fill in the rest, it just copies A, B, and C, over and over. If you've tried to create an alphabetic list using Excel's fill handle, you already know that the fill handle can't handle the task.
