Last week we discussed a fun and easy way to compare two lists of data in excel using conditional formatting. In that post, Artem commented,
The quickest way to find all about two lists is to select them both and them click on Conditional Formatting -> Highlight cells rules -> Duplicate Values (Excel 2007). The result is that it highlights in both lists the values that ARE the same. Then in one list non-highlighted are values that are not present in the second list, and opposite for the second list. I think it is sell “geeky”, but it gets job done very very quickly when you don’t want to mess around.
Artem must be an Excel Yoda. I somehow missed this beautiful and dead-simple way to compare lists in Excel. So here, I am documenting that technique so we all remember it and use it.
A Ridiculously easy and fun way to compare 2 lists
[works only Excel 2007+, use the above technique if you are on excel 2003 or earlier]
- Select cells in both lists (select first list, then hold CTRL key and then select the second)
- Go to Conditional Formatting > Highlight Cells Rules > Duplicate Values
- Press ok.
- There is nothing do here. Go out and play!
See the screencast aside to see how this works (click here for a detailed demo).
Hats off to Artem for sharing this beautiful tip with us. Thank you 🙂

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
