Take a look at cell arraysof strings. Use the number directly as indices into a cell array, or convert using some scheme (like 100=1, 234=2, -12=3) first.

num = [1 3 5 4 3 2 2 1] % num van be used as direct indices
words = {'A','B','CC','DDDD','EE'} % list of words

NumInWords = words(num) % output cell array
