Insert rows on change of value in excel table




Issue


Hello,
I have an excel spreadsheet that contains a table. I want a macro of VB to insert a row into the table when the values in a particular column change.
Column A
1
1
1
2
2
3
3
3

would convert to
1
1
1

2
2

3
3
3
any suggestions welcome. I have limited experience in using macros and almost none with VB

Solution


Have you tried a google search?

I found this site:
http://www.mrexcel.com/forum/showthread.php?t=58685

Which provides the following VBA code which seems to work just fine:
Sub InsertRows()
  Dim r As Long, mcol As String, i As Long

' find last used cell in Column A
  r = Cells(Rows.Count, "A").End(xlUp).Row

 ' get value of  last used cell in column A
  mcol = Cells(r, 1).Value

 ' insert rows by looping from bottom
  For i = r To 2 Step -1
     If Cells(i, 1).Value <> mcol Then
       mcol = Cells(i, 1).Value
        Rows(i + 1).Insert
     End If
  Next i

End Sub




How to use this code:
Go to Extra>Macro>Visual Bacis Editor (Alt+F11)
A new window will open.
Go to Insert>Module
Copy and paste the above code in the great white space.
Close the window.
Back in your excel window.
Go to Extra>Macro>Macro's (Alt+F8)
A new small window will open.
Double click "InsertRows" to see the result of the code.

If something is still unclear then post back.
