Please can someone help.

How can I read an Excel 2010 XLSX file in Siebel 8.1 using VBSCRIPT - or is there another way?

I have tried a couple of methods found by search the web but no luck.  However, the articles I found referenced Excel 2003 file whereas I need to read 2010 files.

Below are just code snippets but they show the intended method of trying to open the xlsx file in each case…

Method 1:

Dim excel As Object 
Set excel = CreateObject("Excel.Application")
excel.Application.DisplayAlerts = False                      
excel.Workbooks.Open "E:\\siebfile\\ztest.xlsx"
excel.Visible = False  
...
...

Returns:

Object creation failed - bad object class(SBL-SCR-00156)
