Good Afternoon

I have previously asked the following question, and the code is the accepted answer. It works correctly but is there a faster away, or more efficent solution, either in code or tweaking my Excel settings. The code is running in Excel 2007.

The question:

I am looking to achive the following:

Within column W of a report, which is pull from a sharepoint site, it is possible to have mulitple entry's in the single cell, for example:

Apple;#1;#Orange;#2,#Nut;#14

What I would like is a piece of code which identifies the multiple entry, and creates a single row for each entry within the cell, so from the above example I would have three rows, with only one entry within the column W. The details held within the rest of the row apply to each entry, so a straight copy of the row would work.

The multiple entrys could be upto a maximum of 21 items.

Many thanks

The code:
Sub splitme()
Application.ScreenUpdating = False
Dim ws As Worksheet
Set ws = ActiveSheet
Dim r As Range
Dim V As Variant
Dim a() As String
Dim i As Integer
Dim row As Long
Dim endRow As Long
Set r = Intersect(ws.UsedRange, ws.Range("W:W"))
row = r.row
endRow = r.row - 1 + r.Rows.Count
While row <= endRow
Set r = ws.Range("W" & row)
a = Split(r.Value, ";")
If UBound(a) > 2 Then
r.Value = a(0) & ";" & a(1)
For i = 2 To UBound(a) Step 2
V = r.EntireRow
r.EntireRow.Insert
r.EntireRow.Offset(-1) = V
'Set r = r.Offset(1)
If UBound(a) >= i + 1 Then
    r.Value = a(i) & ";" & a(i + 1)
Else
    r.Value = a(i)
End If
Next i
End If
row = r.row + 1
Wend
Application.ScreenUpdating = True
End Sub

Ah I see, you have a lot of data and it takes to long to run?

Well a way to speed up, and again it is limited by the amount of data you are having, is to handle everything in variables (Dataranges) and when everything is calculated just overwriting the entire sheet, that will be much faster then inserting rows..


Kind regards

With 10705 rows of data, Excel is freezing, and when it does successfully complete its taking over 3hrs! I am asking if there is a more effective way of achieving my requirement?

And after excel ahs finished how many rows do you have?

I need to now this to be able to see if you can do this with variable Arrays

Kind regards

There are 60 columns, and after the code has run I am left with about 15203 rows.

Hi Washcare,

with this code you load your data into a array
Dim shtrng(20000, 60) As Variant
Dim lastrow, i, j As Integer
 ActiveSheet.UsedRange.Rows.Count
 For i = 1 To lastrow
    For j = 1 To 60
        shtrng(i, j) = Cells(i, j)
    Next j
 next i


then you can run over the sheet again and paste the row whilst dissasembling columns W like shown above.
If you need me to re write the code I can do but only tomorrow. today I won't have anymore time to help...

sorry little mistake

Dim shtrng(20000, 60) As Variant
Dim lastrow, i, j As Integer
 lastrow = ActiveSheet.UsedRange.Rows.Count
 For i = 1 To lastrow
    For j = 1 To 60
        shtrng(i, j) = Cells(i, j)
    Next j
 Next i


this is the correct code.

Hi,

Try this code.

Kris


Sub kTest()
    Dim x, k(), ka, i As Long, n As Long, j As Long, c As Long
    
    Const TotalCols As Long = 60
    Const SplitCol  As Long = 23 'W
    
    ka = ActiveSheet.UsedRange.Resize(, TotalCols)
    ReDim k(1 To UBound(ka, 1) * 15, 1 To TotalCols)
    
    For i = 1 To UBound(ka, 1)
        x = Split(ka(i, SplitCol), ";")
        For j = 0 To UBound(x) Step 2
            n = n + 1
            For c = 1 To UBound(ka, 2)
                If UBound(x) >= j + 1 Then
                    If c = SplitCol Then
                        k(n, c) = x(j) & ";" & x(j + 1)
                    Else
                        k(n, c) = ka(i, c)
                    End If
                Else
                    If c <> SplitCol Then
                        k(n, c) = ka(i, c)
                    Else
                        k(n, c) = x(j)
                    End If
                End If
            Next
        Next
    Next
    Range("a1").Resize(n, TotalCols).Value = k
End Sub
