I would think it will depends on how you plan to use. One of the most easy way and one size fit all way that I can think of is that the you have a hidden sheet, and use change_event to keep updating sheet to store unique records

How exactly you plan to use those unique values in formula ?
Hi, I have a sheet with,

Paul 10
Paul 5
Paul 10
Ben 3
Ben 5
Alan 2

The result must show,

Paul 25
Ben 8
Alan 2

I have 50 arays in 1 sheet so sorting them manualy wont work.

Hope this helps, thanks for the help!!!

I am not saying that you manually update. What I am trying to say is that, there is some place where data is written or updated. When you update that area/range you would like to get a unique items from that area. Taking your example lets say name are in column A and values are in column B. What I am saying is that have a code that update the list of unique items in column A when ever a cell in Column A is changed. This can be done via change event of worksheet. That event will fire off when there is a change in column A and will but the latest set of unique values on a hidden sheets / or a visible sheet depending on your call. Then you can use that updated sheet to do what you want to do
Hi, this is the result I was looking for.

In cell B1 =IF(OR(ISBLANK(A1),A1="0"),"",ROW())
In cell C1=IF(ROW(A1)-ROW(A$1)+1>COUNT(B$1:B$10),"",INDEX(A:A,SMALL(B$1:B$10,1+ROW(A1)-ROW(A$1))))

Coulm A Start and C end result

A B C
1 MARIO 1 MARIO
2 LUIGI 2 LUIGI
3 TOAD
4 TOAD 4 YOSHI
5
6 YOSHI 6

Just one problem, I have a formula in my blank cells, do you know how to change the formula to ignore the formula and see it as blank??

Thanks again for your help

instead of ISBLANK(A1)
try
A1=""
presuming that your formula is putting ""
Thanks, it worked! Changed it to =IF(OR(A1=""),"",ROW())

You can mark this as solved, dont know where to.

Thanks for the help!!!!
