```You have stated what you want to do; since, it is not clear what problem you
are trying to solve I point to the Mathematica built in function
ToCharacterCode[]

Plus[Plus[ToCharacterCode[ToLowerCase["abcdefghijklmnopqrstuvwxyz"]], -32] -64]
{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21,
22, 23, 24, 25, 26}

For uppercase

Plus[ToCharacterCode["ABCDEFGHIJKLMNOPQRSTUVWXYZ"], -32]

{33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51,
