Hi everyone,

I would appreciate if anyone can help me. I am trying to write a code, which will find duplicates within two given columns. However, I need only "pairs" to be found - not all duplicates at one time. For example, if column A has 3 values of 50 and column B only two values of 50 - code will find only two values in column A and two in column B - i.e. pairs. Can you please help me?
 

Excel Facts

Difference between two dates
Secret function! Use =DATEDIF(A2,B2,"Y")&" years"&=DATEDIF(A2,B2,"YM")&" months"&=DATEDIF(A2,B2,"MD")&" days"
After you find the duplicates then what? highlight the cells with yellow?

Try this, I put the result in sheet2, you can change it in this line:
Code:
If k > 0 Then Sheets("Sheet2").Range("A2").Resize(k, 2) = vc
The code:

Thank you so much! It works great!!

I just wanted to ask - can i use this code if I want to add a condition for matching?

Example:
price1 in column A
name1 in column B
price2 in column C
name2 in column D

If price1 and price2 are duplicate pairs, then check if name1 and name2 of the found pair is the same
If both conditions are true for the duplicate pair, cut and paste to the new spreadsheet

Note: I put the result only in column A:B, because the result in column C:D actually are always be the same with column A:B.

This works amazing! I really appreciate your efforts and time! Can you just add C:D in the output range too?

Ok, just replace this line:
Code:
If k > 0 Then Sheets("Sheet2").Range("A2").Resize(k, 2) = vc
with this:
Code:
If k > 0 Then
Sheets("Sheet2").Range("A2").Resize(k, 2) = vc
Sheets("Sheet2").Range("C2").Resize(k, 2) = vc
End If
