New to VBScript -> Convert .rpt to .xls

Hi,
 
I am new to VB Scripting. I want to convert a .rpt file (Crystal Report file) or even a .pdf file to an Excel file (.xls, must be 97-2003 version). The formatting should be same, i.e. excel to have exact format as the .rpt file.
 
I basically want to pass the .rpt file path and name as an input /argument and output the .xls file, by calling the vb script. I will be invoking this .vbs file (VB script) from another application. Any kind souls out there to help me with my case.
 
PS: If input can't be given as .rpt, it would still be fine with me to pass .pdf as an input argument.

This might be a starting point.

Hi
 
So far I managed to write a .vbs that opens the crystal report. I am using Crystal Reports Viewer 2008.
 
'Code Starts
Option Explicit
Dim oRpt, oApp, x
Set oApp = Wscript.CreateObject("Wscript.Shell")
oRpt = "C:\Program Files\Crystal Reports Viewer 2008"
x=Chr(34) & "C:\Documents and Settings\tazz\Desktop\strat.rpt" & Chr(34)
oApp.Run Chr(34) & oRpt & "\CrystalReportsViewer.exe" & Chr(34) & x, 0, "FALSE"
'Code Ends
 
The above .vbs, when run from cmd prompt, manages to open the .rpt file using crystal reports viewer 2008. After opening .rpt file, I am manually exporting to Excel. I want to implement the exporting to excel part, in my above .vbs code. I know there are some .exportexcel options or something of this sort. I am not sure how to do that, any help/ code would be great for me.
 
My objective : I have .rpt file as an input. I simply want to convert it to a .xls file with retaining format of crystal report. (Just like manually opening a crystal report, exporting to excel 97-2003 and selecting 'OK' when the excel format dialog box pops up)
 
Waiting for some kind souls out there to help!
