Related to Excel VBA - I have a large dataset and would like to split it by Ratings. For a small dataset the code works perfectly, but for a large dataset (11,000 rows & 20 columns), it loops and either get "Restart Excel program" or a 438 error. Need some help to optimize/correct the code. Using Excel 2013
I tried Cut/paste instead of copy/paste - it does not work
Private Sub SplitData_Click()
a = Sheets("Sheet1").Cells(Rows.Count, 1).End(xlUp).Row
For i = 2 To a
If Sheets("Sheet1").Cells(i, 2).Value = "AAA" Then
Sheets("Sheet1").Rows(i).Cut
Sheets("Sheet2").Activate
b = Sheets("Sheet2").Cells(Rows.Count, 1).End(xlUp).Row
Sheets("Sheet2").Cells(b + 1, 1).Select
ActiveSheet.Paste
End If
If Sheets("Sheet1").Cells(i, 2).Value = "BBB" Then
Sheets("Sheet1").Rows(i).Cut
Sheets("Sheet3").Activate
c = Sheets("Sheet3").Cells(Rows.Count, 1).End(xlUp).Row
Sheets("Sheet3").Cells(c + 1, 1).Select
ActiveSheet.Paste
End If
If Sheets("Sheet1").Cells(i, 2).Value = "CCC" Then
Sheets("Sheet1").Rows(i).Cut
Sheets("Sheet4").Activate
d = Sheets("Sheet4").Cells(Rows.Count, 1).End(xlUp).Row
Sheets("Sheet4").Cells(d + 1, 1).Select
ActiveSheet.Paste
End If
Sheets("Sheet1").Activate
Next
Application.CutCopyMode = False
End Sub
I want to split the large data set into different groups (Sheets) based on the value - AAA, BBB or CCC. I have 10 such value flags.

Here is an option without using copy/paste
Private Sub SplitData_Click()
Dim a As Long
Dim b As Long
Dim c As Long
Dim d As Long
Dim i As Long
Dim ws1 As Worksheet
Dim ws2 As Worksheet
Dim ws3 As Worksheet
Dim ws4 As Worksheet
Set ws1 = ThisWorkbook.Sheets("Sheet1")
Set ws2 = ThisWorkbook.Sheets("Sheet2")
Set ws3 = ThisWorkbook.Sheets("Sheet3")
Set ws4 = ThisWorkbook.Sheets("Sheet4")
With Application
.ScreenUpdating = False
.Calculation = xlCalculationManual
End With
a = ws1.Cells(Rows.Count, 1).End(xlUp).Row
For i = 2 To a
If ws1.Cells(i, 2).Value = "AAA" Then
b = ws2.Cells(Rows.Count, 1).End(xlUp).Row + 1
ws2.Rows(b).Value = ws1.Rows(i).Value
End If
If ws1.Cells(i, 2).Value = "BBB" Then
c = Sheets("Sheet3").Cells(Rows.Count, 1).End(xlUp).Row + 1
ws2.Rows(c).Value = ws1.Rows(i).Value
End If
If ws1.Cells(i, 2).Value = "CCC" Then
d = Sheets("Sheet4").Cells(Rows.Count, 1).End(xlUp).Row + 1
ws2.Rows(d).Value = ws1.Rows(i).Value
End If
Next i
With Application
.ScreenUpdating = True
.Calculation = xlCalculationAutomatic
End With
End Sub

Try this. This should be faster as this doesn't involve ANY looping.
Logic
Code
Dim wsInput As Worksheet
Sub SplitData_Click()
Dim wsOutputA As Worksheet
Dim wsOutputB As Worksheet
Dim wsOutputC As Worksheet
Set wsInput = ThisWorkbook.Sheets("Sheet1")
Set wsOutputA = ThisWorkbook.Sheets("Sheet2")
Set wsOutputB = ThisWorkbook.Sheets("Sheet3")
Set wsOutputC = ThisWorkbook.Sheets("Sheet4")
Dim lrow As Long
Dim rng As Range
With wsInput
.AutoFilterMode = False
lrow = .Range("A" & .Rows.Count).End(xlUp).Row
Set rng = .Range("A1:A" & lrow)
'~~> Filter on AAA
HandleIt "AAA", rng, wsOutputA
'~~> Filter on BBB
HandleIt "BBB", rng, wsOutputB
'~~> Filter on CCC
HandleIt "CCC", rng, wsOutputC
'~~> Filter on blanks
With rng
.AutoFilter Field:=1, Criteria1:="="
.Offset(1, 0).SpecialCells(xlCellTypeVisible).EntireRow.Delete
End With
.AutoFilterMode = False
End With
End Sub
Private Sub HandleIt(AFCrit As String, r As Range, wks As Worksheet)
Dim OutputRow As Long
Dim filteredRange As Range
With r
.AutoFilter Field:=1, Criteria1:=AFCrit
Set filteredRange = .Offset(1, 0).SpecialCells(xlCellTypeVisible).EntireRow
End With
If Not filteredRange Is Nothing Then
With wks
OutputRow = .Range("A" & .Rows.Count).End(xlUp).Row + 1
filteredRange.Copy .Rows(OutputRow)
filteredRange.ClearContents
End With
End If
wsInput.ShowAllData
End Sub
In Action
Note: The above code took 4 seconds on 21k rows x 31 columns data

Another approach:
Private Sub SplitData_Click()
Dim a As Long, i As Long, sht As Worksheet, sDest As String
Set sht = Sheets("Sheet1")
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
a = sht.Cells(sht.Rows.Count, 1).End(xlUp).Row
For i = a To 2 Step -1 'work from bottom up
sDest = ""
'need to cut this row?
Select Case sht.Cells(i, 2).Value
Case "AAA": sDest = "Sheet2"
Case "BBB": sDest = "Sheet3"
Case "CCC": sDest = "Sheet4"
End Select
'cut row to relevant sheet
If Len(sDest) > 0 Then
sht.Rows(i).Cut Sheets(sDest).Cells(Rows.Count, 1).End(xlUp).Offset(1, 0)
End If
Next i
Application.CutCopyMode = False
Application.Calculation = xlCalculationAutomatic
End Sub
NOTE: locating the "cut to" cell using xlUp
relies on every previous row in the destination sheet having a value in ColA - if any are empty then rows could get overwritten by the next pasted row.

Please see How to avoid using Select in Excel VBA.
Option Explicit
Private Sub SplitData_Click()
Dim i As Long
With Worksheets("Sheet1")
For i = 2 To .Cells(.Rows.Count, 1).End(xlUp).Row
Select Case .Cells(i, 2).Value
Case "AAA"
MoveToEndOf .Rows(i), Worksheets("Sheet2")
Case "BBB"
MoveToEndOf .Rows(i), Worksheets("Sheet3")
Case "CCC"
MoveToEndOf .Rows(i), Worksheets("Sheet4")
End Select
Next
End With
End Sub
Private Sub MoveToEndOf(ByVal what As Range, ByVal where As Worksheet)
what.Cut where.Cells(where.Rows.Count, 1).End(xlUp).Offset(1, 0)
End Sub
