Whats the quickest way to convert letters to numbers, a = 1, b = 2, c =
3, .....z = 26.
i.e. the cat sat on ............
would look like
20,8,5, 3,1,20, 19,1,20, 15,14,
..................
so my child can convert "secret codes" with her friends.

Prefer the numbers to be displayed above the letter.

I can only think of excel to do this is this possible with Word?

Thanks in advance

Mike
