Situation
We know that VLOOKUP formula is useful to fetch the first matching item from a list. So what would you do if you need 2nd (or 3rd etc.) matching item from a list?
For eg. If you have below data, and you want to find out how much sales John made 2nd time, then VLOOKUP formula becomes quite useless. Or is it?!?
Data:

Solution
A simple solution to this problem would be sorting our data on sales person’s name. That way all Johns would line up one beneath another. And we just have to find the first John’s position and add 1 to it to get to 2nd occurrence. Like this =MATCH("John", C5:C17, 0) + 1
But sorting is not an option all the time. So there should be a better way to do this?
Well, there is. We just add a helper column before the sales person name and fill it with sales-person’s name & occurrence. (see the below data table).
For this we can use COUNTIF() Formula, like this: =C5&COUNTIF($C$5:C5,C5). Notice the $C$5:C5?, well the mix of absolute & relative references does the trick here and gets John1, John2… etc.
Now, to lookup 2nd occurance of John, all we do is, simply write =VLOOKUP("John2",...) and we are done.

The file includes few examples on how to fetch 2nd, 3rd etc. matches using lookup formulas. It also has some interesting (and challenging) home work for you. Download & play with it.

Pivot Table will involve manual intervention; hence I prefer to use the 'countif remove duplicate trick' along with 'text sorting formula trick; then using the offset with len to name the final range for validation.
if using the pivot table, set the sort to Ascending, so the list in the validation cell comes back alphabetically.
Hui: Brillant neat idea.
Vipul: I am intrigued by what you are saying. Please is it possible to show us how it can be done, because as u said Hui's method requires user intervention.
Thks to PHD and all

Table names dont work directly inside Data validation.
You will have to define a name and point it to the table name and then use the name inside validation
Eg MyClient : Refers to :=Table1[Client]
And then in the list validation say = MyClient
Kieranz,
Pls download the sample here http://cid-e98339d969073094.skydrive.live.com/self.aspx/.Public/data-validation-unsorted-list-example.xls
Off course there are many other ways of doing the same and integrating the formulae in multiple columns into one.
Pls refer to column FGHI in that file. Cell G4 is where my validation is.
Vipul:
Many thks, will study it latter.

[...] to chandoo for the idea of getting unique list using Pivot tables. What we do is that create a pivot table [...]
@Vipul:
Thanks, that was awesome! 🙂
@Playercharlie Happy to hear that 🙂
Great contribution, Hui. Solved a problem of many years!
Thanks to you, A LOT
Hi Hui,
Greeting
hope you are doing well.
I'm interested to send you a private vba excel file which i need to show detail of pivot in new workbook instead of showing in same workbook as new sheet.
Please contact me on muhammed.ye@gmail.com
Best Regards
