"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Try this :

Set ObjExcel = New Excel.Application
    ObjExcel.SheetsInNewWorkbook = 1
    'Disable command button to prevent object being recreated
    cmdEngreport.Enabled = False
    ObjExcel.Workbooks.Open (App.Path & "\Book1.xls")

with ObjExcel.Activesheet  
  .Cells(Row, 1).Value = name
  .Cells(Row, 2).Value = barcode
  .Cells(Row, 3).Value = quantity
End With
'   Saves report with a new filename
    ObjExcel.ActiveSheet.SaveAs (App.Path & "\Book2.xls")
'   Quit Excel
'   Clear our pointer to excel
    Set ObjExcel = Nothing
Just got started myself
Hope this gets you on the right track

Dim WithEvents vbExcel As Excel.Application

Dim mySheets As Excel.Sheets
Dim mySheet As Excel.Worksheet
Set vbExcel = CreateObject "Excel.Application")
' add new with template
Call vbExcel.Workbooks.Add(Template:="e:\Temp\cor\cor.xlt")
Set mySheets = vbExcel.ActiveWorkbook.Worksheets
Set mySheet = mySheets.Item("Urlaub")
'use named fields (in template)
vbExcel.ActiveWorkbook.Names("Name").RefersToRange.Value = "Name"
'fails if user cancels !!!!!!!!!!!!!
vbExcel.ActiveWorkbook.SaveAs "e:\Temp\name.xls"

vbExcel.ActiveWorkbook.Saved = True
vbExcel.ActiveWorkbook.Close   SaveChanges:=False
Set mySheets = Nothing
Set mySheet = Nothing
Set vbExcel = Nothing

Just one little thing
How do I add a formula say Sum of 5 Cells
ActiveCell.FormulaR1C1 = "=SUM(R[-5]C:R[-1]C)"
The code given is not a complete solution but should give you an idea of how to DIY the rest.

Dim xlApp
Dim xlSheet

'Open an Excel Spreadsheet
Set xlApp = CreateObject("Excel.Application")
'Uncomment next line if you want to see what is going on in your Excel Sheet
'xlApp.Visible = True
Set xlSheet = xlApp.ActiveSheet

xlSheet.Name = "My Sheet1"
'Header row
xlSheet.Cells(1, 1) = "Product Name" 'meaning Row=1 Column=1
xlSheet.Cells(1, 2).Value = "Barcode"  'meaning Row=1 Column=2
'Row = 200, Column = 5 that is where your formula can be
xlSheet.Cells(200, 5).FormulaR1C1 = "=Sum(R2C5:R199C5)"

xlSheet.SaveAs "C:\My Sheet.xls"
Set xlSheet = Nothing
Set xlApp = Nothing

Good Luck
