If you want to open Excel sheet using QTP, follow the below 
script:
Dim objexcel
Set objExcel = createobject("Excel.application") 

Set objWB = objExcel.Workbooks.Open("FileName")
Set objWS = objExcel.ActiveWorkbook.Worksheets("SheetName")
objexcel.Visible = True

HI All,
 
Try for this three ways given below : 

 1. 
  SystemUtil.Run "excelsheet path"

 2.
  Dim xl 
  Set xl=CreateObject("Excel.Application")
  xl.Visible=True
  xl.WorkBooks.Open "ExcelSheet path"
  xl.ActiveWorkBook.Save
  xl.Application.Quit
  Set xl=Nothing

3.Dim xl
  Set xl=CreateObject("WScript.Shell")
  xl.Run "Excel.exe"

We can open a excel sheet from the given location. 
First you write a script in ksh shell and mentioned the
actual path of the sheet and try to run your script.
