I have an alphanumeric numbering system. I need to sort it.
A, AA, AB, AC, AD, AE... AZ then B, BA, BB, BC, BD, BE.... BZ then C, CA, CB, CC, CD... CZ then D, DA, DB through to Z, ZA, ZB, ZC.... etc. After that it's 1, 1A, 1B, 1C.. 1Z then 1AA, 1AB.... 1ZZ, 2A, 2B.... get the drift!?
Anyway, what's the best way to create this in Excel so I can sort my revision control data. I was amazed to find that Excel didn't have a basic alphabet series in the series list. It's not a million miles away from a hexadecimal system, so it can't be that hard.
I know I can type a huge list and then import a custom series, but is there a better way? Is a custom number format a better option?
