    Report on potential duplicates

    Is it possible to identify potential duplicates in Excel and report on them?

    See attahced

    I have two columns, one with a contcat name and another with contact email address. A5 and A6 have similar names and the same email address in columb B. I would like my report to inidcate these as potential duplicates so that they can be looked into further and possibly merged

    Perhaps:

    =FILTER(A2:B6,COUNTIF(B2:B6,B2:B6)>1)

    LOTS of ways... one is :

    =IF(COUNTIF(B$2:B2,B2)>1,"Duplicate","")

    or (delete expected resultrs first, if any):

    =IF(MAP(B2:B6,LAMBDA(x,COUNTIF(B2:x,x)))>1,"Duplicate","")

    no copy/paste needed.

    Another option, using conditional format

    =COUNTIF($B:$B,$B1)>1

    applied to $A:$B
