Counting groups in a list

Attachment 199784Hi all, i have attached a file to better describe my issue, essentially I would like to count all the 'A's, all the 'B's and so on in the file and have the count next to it, so something like

A 6
B 3
D 5
F 1

In the file I uploaded I have column B as a count of the numbers, is there a way I could get just the final number for each letter, that would solve my problem. But if there is a simpler more elegant way then please let me know

Thanks

Are you sure you attached the correct file? I can't figure out what you want to calculate from the example.
Perhaps if you reposted it with the results you want to see.

Much better...
With
D2: a letter...A

This regular formula returns the count of that letter in Col_A
E2: =COUNTIF($A$2:$A$20,D2)

Is that something you can work with?
