Macro help needed

[Mark]

I need help with a macro.

I need it to start at the top of the spreadsheet. Then look at the data in
one cell and compare it to the data in the cell below it . If it is the same
i need it to keep checking until it changes. when the data changes i need it
to insert a new row. then begin the task again till it reaches the end of the
spreadsheet.

thanks in advance for any help you can provide.

Hi
try the following macro. It tests column B and inserts a row if
the values change
Sub insert_rows()
Dim lastrow As Long
Dim row_index As Long

lastrow = ActiveSheet.Cells(Rows.count, "B").End(xlUp).row
For row_index = lastrow - 1 To 1 Step -1
If Cells(row_index, "B").Value <> Cells(row_index + 1, "B").Value _
Then
Cells(row_index + 1, "B").EntireRow.Insert (xlShiftDown)
End If
Next
End Sub
