Transpose and VBA Resize command

[Guest]

Dear All,

Thanks to Bernie I have solved a big problem. (Bernie, I started a new
thread in case you wouldn't pick it up in the old one.)

The code below provided by Bernie is working really well. There is one
slight problem - the speed of the execution when there is a large amount of
data. If I turn the calculation off before and back on after it does not
improve the speed. It seems to be down to the Resize command. Is there a way
to make it faster? Any help much appreciated.

Sub MartinDataRearrange()
Dim myA As Range
Dim myR As Range
Dim mySel As String
Dim myRow As Long
Dim i As Long

mySel = Selection.Address

With Application
.ScreenUpdating = False
.EnableEvents = False
End With

myRow = Cells(Rows.Count, 1).End(xlUp).Row

For i = myRow To 2 Step -1
Cells(i, 1).EntireRow.Copy
Cells(i, 1).Resize(9).Insert
Cells(i, 1).Offset(1, 11).Resize(9, 244).ClearContents
Next i

Set myR = Range("L2:U2").Resize((myRow - 2) * 10 + 1). _
SpecialCells(xlCellTypeConstants)

For Each myA In myR.Areas
myA.Cells.Copy
Cells(myA.Cells(1, 1).Row, 2).Resize(10).PasteSpecial Transpose:=True
Next myA

Set myR = Range("V2:AE2").Resize((myRow - 2) * 10 + 1). _
SpecialCells(xlCellTypeConstants)

For Each myA In myR.Areas
myA.Cells.Copy
Cells(myA.Cells(1, 1).Row, 4).Resize(10).PasteSpecial Transpose:=True
Next myA

Range("L:AE").EntireColumn.Delete

Range(mySel).Select

With Application
.ScreenUpdating = True
.EnableEvents = True
End With

End Sub

This seems to produce the same output and should be Faster.

Sub MartinDataRearrangeV2()
Dim mySel As String
Dim myRow As Long, i As Long
Dim j As Long, k As Long
Dim v As Variant, vB As Variant
Dim vD As Variant, cnt As Long
Dim vAK As Variant, vAK_Exp As Variant
mySel = Selection.Address

With Application
.ScreenUpdating = False
.EnableEvents = False
End With
myRow = Cells(Rows.Count, 1).End(xlUp).Row
cnt = myRow - 1
ReDim vB(1 To cnt * 10, 1 To 1)
ReDim vD(1 To cnt * 10, 1 To 1)
ReDim vAK_Exp(1 To cnt * 10, 1 To 11)

v = Range("L2:AE" & myRow)
vAK = Range("A2:K" & myRow)
For i = 1 To cnt
For j = 1 To 10
vB((i - 1) * 10 + j, 1) = v(i, j)
Next j
For j = 11 To 20
vD((i - 1) * 10 + j - 10, 1) = v(i, j)
Next
For k = 1 To 10
For j = 1 To 11
vAK_Exp((i - 1) * 10 + k, j) = vAK(i, j)
Next
Next
Next i
Range("A2:K" & cnt * 10 + 1).Value = vAK_Exp
Range("B2:B" & cnt * 10 + 1) = vB
Range("D2" & cnt * 10 + 1) = vD
Range("L:AE").EntireColumn.Delete
End Sub

Thanks Tom,

That seems to be working like a dream. However, sorry for being so stupid
but I was then trying amend the code into a bigger picture and cannot get it
to work. A wider range and more sets of data to transpose. I would appreciate
a lot if you were able to help and see why it is going wrong.

Variant, cnt As Long

It is hard to tell what you are trying to do, but you dimension your arrays
to be a single column, then when you write them to the worksheet, you write
them to a multicolumn range.

Are you trying to have multiple columns all with the same information or
should you be constructing and populating your arrays differently?

Hi Tom,

Please find below an explanation of what I was trying to change the code into.

Lets say we have 50 rows of data. (The number of rows could vary from 1 to
around 8000 to 10,000):

1. Add 9 empty rows after each row of data. After this exercise we should
have 500 rows. 50 with data and another 450 without any data.

2. Now I want to copy the A2:AH2 down to A3:AH11. (No transposing yet)

3. Then A12:AH12 to A13:AH21. (No transposing yet)

4. Then A22:AH22 to A23:AH31 until all the emtpy rows are taken care of (No
transposing yet)

5. Now it's time for transposing. The data in AI2:AR2 (10 cells) to be
copied into V2:V11 (10 cells), AS2:BB2 into W2:W11, BC2:BL2 into X2:X11,
BM2:BV2 into Y2:Y11, BW2:CF2 into B2:B11, CG2:CP2 into AE2:AE11, CQ2:CZ2 into
AF2:AF11, DA2J2 into AG2:AG11 and DK2T2 into AH2:AH11

6. The data in AI12:AR12 (10 cells) to be copied into V12:V21 (10 cells),
AS12:BB12 into W12:W21, BC12:BL12 into X12:X21, BM12:BV12 into Y12:Y21,
BW12:CF12 into B12:B21, CG12:CP12 into AE12:AE21, CQ12:CZ12 into AF12:AF21,
DA12J12 into AG12:AG21 and DK12T12 into AH12:AH21


7. The data in AI22:AR22 (10 cells) to be copied into V22:V31 (10 cells),
AS22:BB22 into W22:W31, BC22:BL22 into X22:X31, BM22:BV22 into Y22:Y31,
BW22:CF22 into B22:B31, CG22:CP22 into AE22:AE31, CQ22:CZ22 into AF22:AF31,
DA22J22 into AG22:AG31 and DK22T22 into AH22:AH31 until all the 50 sets
of have been taken care of.
