Finding duplicate rows in excel

Question

I have an excel spreadsheet with two rows. One is for name, and the other is for id. Is there any way i can find the rows that have the exact same id and allow me to easily

Answer 1

In the third column you could add this formula (cell B3 example) :

=IF(COUNTIF(B$2:B$7,"="&B2)>1,"<--Dup!","") 

You will have to adjust the range B$2:B$7 to reflect the actual data range...

Answer 2

The absolute fastest and easiest way. Conditional formatting, highlight duplicates (on the ID column). Then filter the column (presumably in a table) by the coloring (above the check boxes).
