I have 3000 columns, each column containing duplicate values.  I was able to sort each column individually but now I need to remove duplicate values from each column individually while leaving the unique without affecting any other column.  Ive tried several ways but each fails.  Any assistance is appreciated.

If you could attach a small sample workbook with 3 or 4 columns it would help.

This small macro will remove duplicates from each individual column without affecting the data in other columns.
Sub RemoveDuplicates()
Dim lc As Long, c As Long
Application.ScreenUpdating = False

'Assuming the Row1 is the header row
lc = Cells(1, Columns.Count).End(xlToLeft).Column
For c = 1 To lc
    Columns(c).RemoveDuplicates Columns:=1, Header:=xlYes
Next c
Application.ScreenUpdating = True
End Sub

Thank you both.  Martin, I normally do post samples, but Neeraj answered it with the solution before I got back to the question.   Neeraj - Thank you very much that was quick and painless.  I had been trying to do this since last night but the vba solution I was using kept locking everything up and crashing.   thank you for your assistance.
