Excel, clearing contents based on data in the cells, reording data

A sample file is uploaded and I need all multiple appearing names to be cleared from their cells [leaving one occurance of each name].
The remaining unique names to be in the uppermost cell of its section...this is the part that I can't get.
The dup names under the first one -- these cells  should have their contents cleared.
Other column need to remain as-is. [No row deletions].
In the attached sample, for example, the name should appear on row 2 and be deleted from row 3-5.
[I tried removing dups in A column using Trim + Count, but the remaining Name is in the last row of its section
instead of the top row of its section.]  

All help appreciated.

is it acceptable to sort the date first ?

paste this code into a module.  Run with the desired sheet active.
Sub RemoveDup()
'

    Dim rngAll As Range, rngSort As Range
    Dim lastval As String
    Range("A2").Select
    Range(Selection, Selection.End(xlDown)).Select
    Range(Selection, Selection.End(xlToRight)).Select
    
    Set rngAll = Selection
    Set rngSort = rngAll.Columns(1)
    ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Clear
    ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Add Key:=rngSort _
        , SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
    With ActiveWorkbook.Worksheets("Sheet1").Sort
        .SetRange rngAll
        .Header = xlNo
        .MatchCase = False
        .Orientation = xlTopToBottom
        .SortMethod = xlPinYin
        .Apply
    End With

    Set rngSort = Range("A1")
    'lastval = rngSort.Value
    'Set rngSort = rngSort.Offset(1, 0)
    lastval = "===========" 'dummy
    Do While rngSort.Value <> ""
        If rngSort.Value = lastval Then
            'delete the value
            rngSort.Value = ""
         Else
            lastval = rngSort.Value
        End If
        Set rngSort = rngSort.Offset(1, 0)

    Loop
    
End Sub

Nice use of 'Sort' robberbaron. :)

dkoliver: I think this is what you want? Please check the sample file attached. I have colored the cells in 'Yellow' which will not be cleared? If that is correct, then run the Sub RemoveMultipleWords() in the Sample file attached.

Code Used

Sub RemoveMultipleWords()
    Dim i As Long, LastRow As Long
    
    LastRow = Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row
    
    For i = LastRow To 2 Step -1
        If Application.WorksheetFunction.CountIf(Sheets("Sheet1").Range("A2:A" & LastRow), _
        Sheets("Sheet1").Range("A" & i).Value) > 1 Then
           Sheets("Sheet1").Range("A" & i).ClearContents
        End If
    Next
End Sub

dkoliver: Did you see the code that I posted? You might not need to sort...

Yes, thank you, I did see your code and prefer it since it is shorter. I have been left behind in the excel world -- pls. explain how to do this programming -- do I enter as a macro somewhere on the sheet and run it?  Sorry to ask but it's been a long time -- back to Lotus 1-2-3 since I did any macro writing. Thanks!

Please create a module and paste the code in the module.

Press Alt +F11 from the worksheet and in the VBE and check the module that I posted. You can then run the macros.

Perhaps later you might want to see this link to refresh on VBA :)
