Here is my code

VB

'excel
Dim oexcel As Object
oexcel = CreateObject("Excel.Application")
Dim obook As Excel.Workbook
Dim osheet As Excel.Worksheet
Dim fnExc As String
Dim curLine As Integer = 0

' this should be used only once
obook = oexcel.Workbooks.Add

'first
If oexcel.Application.Sheets.Count() < 1 Then
    osheet = CType(obook.Worksheets.Add(), Excel.Worksheet)
Else
    osheet = oexcel.Worksheets(1)
End If
osheet.Name = "Payroll Detail Report"

'second
If oexcel.Application.Sheets.Count() < 2 Then
    osheet = CType(obook.Worksheets.Add(), Excel.Worksheet)
Else
    osheet = oexcel.Worksheets(2)
End If
osheet.Name = "Payroll Detail Report (real)"

'third
If oexcel.Application.Sheets.Count() < 3 Then
    osheet = CType(obook.Worksheets.Add(), Excel.Worksheet)
Else
    osheet = oexcel.Worksheets(3)
End If
osheet.Name = "Payroll Summary Report"

'next
If oexcel.Application.Sheets.Count() < 4 Then
    osheet = CType(obook.Worksheets.Add(), Excel.Worksheet)
Else
    osheet = oexcel.Worksheets(4)
End If
osheet.Move(After:=obook.Worksheets(obook.Worksheets.Count))
osheet.Name = "Weekly Payroll Report - Week 1"


obook.SaveAs(fnExc)
obook.Close()
obook = Nothing
