Hi, Mukesh.
I'm always trying to remove dupes, but I'm really cautious as to not delete
too many.
Try this:
Insert a column and start at the top of your worksheet.
Let's assume your e-mail addresses are in Column A.
In the new column (Column B) enter the following formula:
=IF(A2=A1,"Dupe",IF(A2=A3,"Dupe2","Single"))
Which is essentially saying "Compare the contents of A2 to the row above and
the row below and tell me if the contents is the same. If it's distinct, give
me 'Single' and if it's a duplicate, then label Dupe and Dupe2." Then you
can delete all that say "Dupe" and still keep the individual row that had the
double.
For example
Column A Column B
(e-mail address removed) Dupe
(e-mail address removed) Dupe2
If you delete "Dupe", you will still have "Dupe2" or one row of
(e-mail address removed).
Hope this helps.
