Grouping data

[Rbd340]

Hi,
I'm looking for a way to concatenate vertically based on column A and B and put it in a new tab:
Basically my data looks like this:

Column1 Column2 Column3
A 1 DataXx
A 1 DataAA
A 1 DataBB
A 2 DataXx
A 2 DataCc
A 2 DataAA
B 1 DataCC
B 1 DataAA
B 1 DataFF
B 1 DataWW
B 2 DataRR
B 2 DataXX

and the preferred output would
Column1 Column2 Column3
A 1 DataXx,DataAA,DataBB
B 2 DataXx,DataCc,DataAA
A 1 DataCC,DataAA,DataFF,DataWW
B 2 DataRR,DataXX

Anyone kind enough to help me with this? The excel changes in length and values in column 1 and 2 can have different numbers of rows.
I have to do this a lot and it would help if I have a macro.

Thanks a lot in advance!

I've made an attempt to explain my problem, my goal and with a better example file here:

In that case I am closing this thread to avoid any possibility of the same question continuing in multiple threads.
