How can I do this?

Answer 1

I had to do something similar a while ago. Here are the steps:

1) formula in column D:

= IF (A1=B1, CONCATENATE(C1, ",", C2), "")

2) apply a filter on column D for blank cells

3) delete all rows that have blank column D

4) remove filter

5) delete column C

Note: This is only efficient for "one time use" situations. If you need to do this often, developing a macro may be more efficient.
