I have data in 2 columns that i need to merge.

IE:
A B
234 245

needs to be:
234245

Now i know i can concantenate the data but then i'm stuck.

The data can be of any number of rows, so i need to select only the cells
with data in them. I then have to take the data and transpose it.

IE:
A
234
456
689

needs to be:
A B C
234 456 689.

This way i can save it as comma delimited and import it into another source.
Basically i need my ending data to be 123,345,677,8984.

Any ideas on how to get this all done? I would like to make it a macro so i
dont have to manually do it each time. thanks.
