membagi baris excel dari 1 file menjadi banyak file

kode ini utk split file excel yang terlalu banyak barisnya dan dipecah2 menjadi beberapa file , metode ini saya pakai utk import data DPT KPU ke aplikasi apdalih pro, dimana filenya sangat besar sampai 65.000 baris. karena terlalu besar dan aplikasi gagal import nya maka saya bagi menjadi 1 file utk setiap 3000 baris



Sub Test()
  Dim wb As Workbook
  Dim ThisSheet As Worksheet
  Dim NumOfColumns As Integer
  Dim RangeToCopy As Range
  Dim WorkbookCounter As Integer
  Dim RowsInFile
  Dim Prefix As String

  Application.ScreenUpdating = False

  'Initialize data
  Set ThisSheet = ThisWorkbook.ActiveSheet
  NumOfColumns = ThisSheet.UsedRange.Columns.Count
  WorkbookCounter = 11
  RowsInFile = 3000                   'how many rows (incl. header) in new files?
  Prefix = "KEDUNGADEM"                    'prefix of the file name

  For p = 1 To ThisSheet.UsedRange.Rows.Count Step RowsInFile
    Set wb = Workbooks.Add

    'Paste the chunk of rows for this file
    Set RangeToCopy = ThisSheet.Range(ThisSheet.Cells(p, 1), ThisSheet.Cells(p + RowsInFile - 1, NumOfColumns))
    RangeToCopy.Copy wb.Sheets(1).Range("A1")

    'Save the new workbook, and close it
    wb.SaveAs ThisWorkbook.Path & "\" & Prefix & "_" & WorkbookCounter
    wb.Close

    'Increment file counter
    WorkbookCounter = WorkbookCounter + 1
  Next p

  Application.ScreenUpdating = True
  Set wb = Nothing
End Sub
