Split data in multiple workbooks based on a column

Here, I could find this as the fastest method to split data in multiple workbooks, based on a column values. Irrespective of no. of rows or columns, this will always work.. Wow!!

Sub split()

Dim LastRow As Long, LastCol As Integer, i As Long, iStart As Long, iEnd As Long

Dim ws As Worksheet, r As Range, iCol As Integer, t As Date, Prefix As String

Dim sh As Worksheet, Master As String

Dim wb As Workbook

On Error Resume Next

Set r = Range("C1")    ''Here you can change C to any column, basis which you want to split

On Error GoTo 0

If r Is Nothing Then Exit Sub

iCol = r.Column

t = Now

Application.ScreenUpdating = False

With ActiveSheet

    Master = .Name

    LastRow = .Cells(Rows.Count, "A").End(xlUp).Row

    LastCol = .Cells(1, Columns.Count).End(xlToLeft).Column

    .Range(.Cells(2, 1), Cells(LastRow, LastCol)).Sort Key1:=Cells(2, iCol), Order1:=xlAscending, _

        Header:=xlGuess, OrderCustom:=1, MatchCase:=False, Orientation:=xlTopToBottom

    iStart = 2

    For i = 2 To LastRow

        If .Cells(i, iCol).Value <> .Cells(i + 1, iCol).Value Then

            iEnd = i

            

            Workbooks.Add

         

            Set wb = ActiveWorkbook

            wb.SaveAs Filename:=ThisWorkbook.Path & "\" & .Cells(iStart, iCol).Value & ".xls" 

            On Error Resume Next

           

            On Error GoTo 0

            Set ws = wb.Worksheets(1)

            ws.Range(Cells(1, 1), Cells(1, LastCol)).Value = .Range(.Cells(1, 1), .Cells(1, LastCol)).Value

            .Range(.Cells(iStart, 1), .Cells(iEnd, LastCol)).Copy Destination:=ws.Range("A2")

            iStart = iEnd + 1

            ActiveWorkbook.Close True

        End If

    Next i

End With

Application.CutCopyMode = False

Application.ScreenUpdating = True

MsgBox "Completed in " & Format(Now - t, "hh:mm:ss.00"), vbInformation

     Application.ScreenUpdating = True

End Sub
