Works for me, although it is better if the formula is

=COUNTIF($A:$A,$A1)1

It does not work. It highlighted wrong records which are not duplicated

You don't need a macro, conditional formatting will do it.

Select all the rows.
Menu FormatConditional Formatting
Change Condition 1 to Formula Is
Add a formula of =COUNTIF($A:$A,A1)1
Click Format, select the Pattern tab, and choose a colour
OK out

This assumes the account is in column A, and you start at row 1.

Hi everybody,

I have a chunk of records stored in excel and are tracked by account
number.
Some of the account numbers are duplicated and I wish to run a macro
which
can loop through the records and highlight the row s which have
duplicated
account numbers. How do i do it? Thanks in advance
