Your posting is a bit vague so I don't know if this will help or not.
If your data is is a single column, say A, in another column like D you can
put the formula:

=countif(A:A,A1) This would be in D1. Drag it down the length of your
spreadsheet. It will count the number of times something will appear inthe
column.

Using conditional formatting highlight column A.
Use the formula:
=D12
Set the color of the font to WHITE. (not automatic)
The range should be A:A
