Hi, I've spent days looking for a way to create a number format like this; 01,05,09,13,15-08,10 or this way ; 1,5,9,13,15-8,10 where I can simply enter the numbers, 1591315810 or 01050913150810 and excel would format them that way because I have a lot of numbers to enter. so I would type in please help. I'm desperate.
Thanks in advance
