FIND DUPLICATE
 

Hi,

I have range of data from which i want to duplicate entries. Data in the
Column D contains a unique ID of 4 digits follows with a name. I want to
find whether the Unique ID repeats in the range. If i use =countif(B:B,B2)1
it does not work because I want check only the the Unique ID repeats or not.

Hi shaji,

Assuming your IDs all have four digits, try:
=SUM(IF(LEFT(B$1:B$100,4)=LEFT(B1,4),1,))
entered as an array formula (i.e. input with press <Ctrl-<Shift-<Enter instead of just -<Enter) in the first output cell, then
copy down as far as needed. Change B$1:B$100 to suit your input range and B1 to suit the first cell in that range.

Cheers

Another way ..
In C2: =LEFT(B2,4)
In D2: =IF(C2="","",IF(COUNTIF($C$2:C2,C2)1,"Dup",""))
Select C2:D2, copy down as far as required
Col D will return "Dup" for any duplicates found

=SUMPRODUCT(--(LEFT($B$1:$B$9,4)=LEFT(B1,4)))
