Decoding project. The first step is to combine two sets of info, then use a lookup table.
aabcd deabb 12231 53212
import the text as a column of single one character cells
import the numbers as a single column of one character cells
Combine the two into column 3
a - 1 - a1 a - 2 - a2 b - 2 - b2 c - 3 - c3 d - 1 - d1 d - 5 - d5 e - 3 - e3 a - 2 - a2 b - 1 - b1 b - 2 - b2
Take column 3 and output as text string:
a1 a2 b2 c3 d1 d5 e3 a2 b1 b2
Decoding software, already set up with a lookup table, can take it from there.
Any help appreciated, otherwise I'm going to look a hopeless dad....
