I have a spreadsheet with over 2000 rows of data I would like to quickly
isolate those with duplicate names or phone numbers. Can I do this in Filter?
I know I can eliminate duplicates but I want to find them.

If you just want to identify them and we'll say they are in A1:A2000 then in
a spare column alongside enter

=COUNTIF($A$1:$A$2000,A1)

and copy down

This will give you the number of times they appear in the list and you can
autofilter or sort on that

Actually, I had the same problem once.

First I did sort by this column. Suppose your column is A. on one empty
column, for example E, in cell E2 put formula =If(A1=A2, 1, 0), and extend to
all of the column E. Then all of the duplicated records will be found. sum of
column E, you will know how many duplicates you've got.

Hope it can send you help!

This will give comparision result to one particular cell. What about other
duplicate values.

Thank You

But of course! Thanks - you saved me! Forget the pivotal tables and the
formulas. This is much easier.
