I have a list of values in Column A. In Column B - Row 1 I want to
concatenate the values from Column A - Rows 1-50 with commas in between
each value, and in Column B - Row 2 I want to concatenate the values
from rows 51-100 with commas in between. I'm using a ridiculously long
formula right now to do this.... =A1&","&A2&","&A3&","&A4&","&A5....
and on and on and on...

Can someone please help me write a macro to do this?

Thanks
