Hi
I need a program to be able to concate all the rows in B until the cell in
column A is
not blank. would also want a separator between them.
ie row C1 = 000034001570;000034001571;000034001582;00003400158 9
C6 = 000034032303

A B
1 000034001570 000034001570
2 000034001571
3 000034001582
4 000034001589
5 000034001589
6 000034032303 000034032303
7 000034066598 000034066598
8 000034017214 000034017214
9 000034017215
10 000034019302
11 000034019303

The issue is that I have a sheet of over 40,000 rows, also I have noticed
that I have duplicates in the column B, which will have to be excluded.
Its been a while since I've done any programming so any help appreciated
