I would like to auto-generate a column which has a mixture of both numbers and alphabets. Like AA01 or AC24. I want to start at AA00 until AA40. From here i will go to AB00 until AB40, and do likewise for other subsequent alphabets until the last one which will be AZ40. I just need a start off. I understand i can make use of the ASCII key but dont really understand how. Any help or suggestion is appreciated. Thank you.
