THIS@CODE@USES@PASCALS@THEORY

Thanks to Oscar for the key.  I was working along similar lines but wasn't quite there yet.

What I did was to cut and paste into a spreadsheet;
then use Data   Text to columns to put each letter into its own cell;
Then used the following formula:
CODE(B1) - CODE(A1)    to take the ascii value of "J" minus the ascii value of "P". 
then
CHAR(MOD(B2,26) + 64)   to turn "-6" into "T"

then copied the formulae to the right.
