I am trying to add a zero to the end of a series of numbers. I have a list of 20,000 customer numbers, some with 5 digits and some with 6 digits. Example some are 123456 and some are 12345. I need to make them all 6 digits long, so I decided to add a leading zero to them. I made a custom format and selected 000000, which made it 012345, which worked perfectly. Now however I found out that I need the zero on the end, so 123450. Any ideas on how to format this???
