Background: Opening a tab delimited file, generated by netsh, with Excel to
format the data. Formatting includes creating new worksheets.

Here's the short code in vbscript:
'''''''''''''''''''''''''''''''''''''''''''''''''' '''''''''''''''''''''''''''''''''''''''''''''''''' ''''''''
Set objExcel = WScript.CreateObject("Excel.Application")
'Opening existing Workbook
Set objExcelWorkbook = objExcel.Workbooks.Open(filename)
'Adding worksheet to opened, existing workbook
objExcel.Worksheets.Add
'''''''''''''''''''''''''''''''''''''''''''''''''' '''''''''''''''''''''''''''''''''''''''''''''''''' '''''''''

What happens with the above code is the data in the existing worksheet gets
overwritten, but the name of the worksheet is retained.

Value add:
Any good reference on vbscriipt, Excel specific objects & methods would be
appreciated. VBA references tend toward VB and not VBScript, which means you
waste a lot of time trying to figure out what objects and methods are
available and how they should be formatted.

Thanks in advance.
