How to list duplicates from a list?

Hi Chetan,


I assume your data is from A2 to A11 (A1 is your header) as follows:


Header1

A

B

A

S

D

A

R

A

R

M


Now, at B2, write the following:


=IFERROR(INDEX($A$2:$A$11, MATCH(0, COUNTIF(B1:$B$1, $A$2:$A$11)+IF(COUNTIF($A$2:$A$11,$A$2:$A$11)>1, 0, 1), 0)),"") CTRL + SHIFT + ENTER (to enter it as an array formula) and drag it down as needed.


Note: Change the reference per your need.


Regards,

Kaushik
