Hello,
I need your help please. First, 4 worksheets have a same format (# of
columns, rows, and labels are the same for each col.). How do I comebine or
append them together (from sheet1-4)?

For sample,
A B C
Sheet 1 test1 test2 test3
Sheet 2 test4 test5 test6
Sheet 3 test7 test8 test9
Sheet 4 test10 test11 test12

So, the master should look like this:

Sheet5: A B C
test1 test2 test3
test4 test5 test6
test7 test8 test9
test10 test11 test12

Thanks alot!
