Duplicate rows if cell contains carriage return (or possibly newline)

Hi,

I would like to know how I can duplicate a row if a cell in a particular column has multiple values separated by a carriage return (or maybe its an endline not sure). My data looks something like this:

uniquetext_A text1
text2
uniquetext_B text1
uniquetext_C text1
text2
text3

and the result would ideally be:

uniquetext_A text1
uniquetext_A text2
uniquetext_B text1
uniquetext_C text1
uniquetext_C text2
uniquetext_C text3


I've already tried this:

Sub SplitCarriages() 
    Dim mySplit() As String 
    Dim i As Long, txtCount As Long 
    Dim lastRow As Long, recRow As Long 
    Dim searchCol As String 
    Dim sourceWS As Worksheet, dumpWS As Worksheet 
     
     
     'Which worksheet as we getting data from?
    Set sourceWS = Worksheets("Sheet1") 
     'Which worksheet are we putting data in?
    Set dumpWS = Worksheets("Sheet2") 
     'Which column has carraige returns?
    searchCol = "D" 
     
     
    Application.ScreenUpdating = False 
    dumpWS.Select 
    recRow = 0 
    With sourceWS 
        lastRow = .Cells(.Rows.Count, searchCol).End(xlUp).Row 
         
         'Starting at row 1, presumably
        For i = 1 To lastRow 
            mySplit = Split(.Cells(i, searchCol), Chr(10)) 
            For txtCount = LBound(mySplit) To UBound(mySplit) 
                recRow = recRow + 1 
                 'Copy whole row
                .Cells(i, 1).EntireRow.Copy Cells(recRow, 1) 
                 'Place single line of text
                Cells(recRow, searchCol).Value = mySplit(txtCount) 
            Next txtCount 
        Next i 
    End With 
    Application.ScreenUpdating = True 
     
     
End Sub

And I'm having partial success, with problems though.
Here are my before-after macro pictures of the sheet, and also a link to the original file.
