one way to do it is to create multiple excel files and use a master file to
link them all.

e.g. create 4 files, master.xls, user1.xls, user2.xls, user3.xls
formula in master.xls:

A B C
=[user1.xls]Sheet1!A1. =[user1.xls]Sheet1!B1. =[user1.xls]Sheet1!C1
=[user2.xls]Sheet1!A2. =[user1.xls]Sheet1!B2. =[user1.xls]Sheet1!C2
=[user3.xls]Sheet1!A3. =[user1.xls]Sheet1!B3. =[user1.xls]Sheet1!C3

for this example to work all the files must reside in the same file
directory. another way is to use the same idea but implement it on different
worksheet tabs.

hope this helps.
