Range("A1:Z500").Select
Selection.ClearContents

Set rng1 = Worksheets("sheet1").Range("A1")
Set rng2 = Worksheets("sheet2").Range("A1")

x = rng1.CurrentRegion.Rows.Count - 1
For j = 0 To x
For i = 0 To x
rng2.Offset(j, i) = rng1.Offset(j, 0)
Next i
Next j
For j = 0 To x
rng2.Offset(j, j) = rng1.Offset(j, 0) + 0.1
Next j

End Sub

Sub ProcessData()
Dim i As Integer, Cols As Integer

'move Sheet1 ColA to safe place
Sheets("Sheet1").Activate
[AA:AA].Value = [A:A].Value
'...determine # of loops
Sheets("Sheet2").Activate
Cols = ActiveSheet.UsedRange.Columns.Count

'Start looping

For i = 1 To Cols
'...select Col i from Sheet2, paste to Sheet1 ColA
Columns(i).Copy
Sheets("Sheet1").Columns(1).PasteSpecial
'...Copy Sheet3 Row 1 to Row i in Sheet 4
Sheets("Sheet4").Rows(i).Value = Sheets("Sheet3").Rows(1).Value
