Macro to delete blank rows and run from drop down list

And remove blank rows too

Excellent the macro work but can i use the following to run the macro from a drop down list...

Private Sub Worksheet_Change(ByVal Target As Range) 
    If Target.Address = "$B$2" Then
        Call CopyandPasteValues
    End If
End Sub

Select allOpen in new window

Add the following to ThisWorksheet

That's because your drop down list is in B1 not in B2, so change the following line...

If Target.Address = "$B$2"

Select allOpen in new window

TO THIS

If Target.Address = "$B$1"

Select allOpen in new window

Right click the Master Tab --> View Code and place the following code into the opened code window.

Private Sub Worksheet_Change(ByVal Target As Range) 
    If Target.Address = "$B$1" Then
        Call CopyandPasteValues
    End If
End Sub

Select allOpen in new window

Many thank excellence feedback.

You're welcome. Glad to help.

SpecialCells will cause an error if no cells match the criteria so it's best to use an error handler. If an error occurs and the macro fails then Screen Updating will not be restored automatically. I would amend the code slightly

Option Explicit

Sub CopyandPasteValues()
    On Error GoTo exit_proc
    With Application
        .ScreenUpdating = False
        With Sheets("Unique List")
            .Columns(1).ClearContents
            Sheets("Data").Range("A:A").SpecialCells(xlCellTypeConstants).Copy
            .Range("A1").PasteSpecial Paste:=xlPasteValues
            .Range("A:A").RemoveDuplicates Columns:=1, Header:=xlYes
        End With
exit_proc:
MsgBox "An error occurred", vbCritical, "Quitting"
        .CutCopyMode = False
        .ScreenUpdating = True
    End With
End Sub

Select allOpen in new window

@Roy

There are so many ifs and buts...
like what if Sheet Unique List or Sheet Data doesn't exists in the workbook?
With the kind of error handling you included in your code will suppress the error only, if any, during the code execution and will prompt the user in the end that "An error occurred" but with no clue of what error has been occurred. In other words, this will only stop the debug window to appear.
Won't it be better if the error message also includes the Err.Description, I think then only your error handling makes any sense.

Makes more sense than no error handling. It was only a quick suggestion

Amended code

Option Explicit

Sub CopyandPasteValues()

    On Error GoTo exit_proc

    On Error GoTo exit_proc
    With Application
        .ScreenUpdating = False
        With Sheets("Unique List")
            .Columns(1).ClearContents
            Sheets("Data").Range("A:A").SpecialCells(xlCellTypeConstants).Copy
            .Range("A1").PasteSpecial Paste:=xlPasteValues
            .Range("A:A").RemoveDuplicates Columns:=1, Header:=xlYes
        End With
exit_proc:
        MsgBox "Error " & Err.Number & " (" & Err.Description & ") in procedure CopyandPasteValues of Module Module1"
        .CutCopyMode = False
        .ScreenUpdating = True
    End With
    On Error GoTo 0

End Sub

I am happy that you got my point. :)

I didn't get your point, I was only trying to help  the OP by suggesting a slight amendment to your code. Didn't expect criticism from you when I didn't start by criticizing your original post. My point was simply really to avoid an error using SpecialCells. I then noticed ScreenUpdating, which can be very confusing to a beginner if it is not restored by the code, I don't really see what advantage there is in using it with your code, but it wouldn't be a problem unless an un-trapped error occurred.

I've just spotted a typo in my code, it should be

Option Explicit


Sub CopyandPasteValues()

    On Error GoTo exit_proc
   
    With Application
        .ScreenUpdating = False
        With Sheets("Unique List")
            .Columns(1).ClearContents
            Sheets("Data").Range("A:A").SpecialCells(xlCellTypeConstants).Copy
            .Range("A1").PasteSpecial Paste:=xlPasteValues
            .Range("A:A").RemoveDuplicates Columns:=1, Header:=xlYes
        End With
exit_proc:
        MsgBox "Error " & Err.Number & " (" & Err.Description & ") in procedure CopyandPasteValues of Module Module1"
        .CutCopyMode = False
        .ScreenUpdating = True
    End With
    On Error GoTo 0

End Sub

Select allOpen in new window

Although I think this is all that is bneeded

Option Explicit


Sub CopyandPasteValues()

    On Error GoTo exit_proc

        With Sheets("Unique List")
            .Columns(1).ClearContents
            Sheets("Data").Range("A:A").SpecialCells(xlCellTypeConstants).Copy
            .Range("A1").PasteSpecial Paste:=xlPasteValues
            .Range("A:A").RemoveDuplicates Columns:=1, Header:=xlYes
        End With
exit_proc:
        MsgBox "Error " & Err.Number & " (" & Err.Description & ") . Probable cause is that no cells could be found for the macro to work with"
        Application.CutCopyMode = False
    On Error GoTo 0

End Sub
