A mapping for all your assignments:

$CharMap = Dispatch@Join[
    Thread[CharacterRange["a", "z"] -> Range[1, 26]],
    Thread[CharacterRange["A", "Z"] -> Range[27, 52]],
    {_ :> Throw["Unknown"]}
    ];

A function which takes a string, and applies the mapping:

convert[s_String] := Replace[Characters[s], $CharMap, {1}];
