How to use the for loop while using Excel import to local datasheet?

[Uma]

Hi,
In my Excel sheet The first row i am having heading,
2and 3 rd row I am having values.
I am importing this excel sheet to local data sheet.
My script is like this,

Code:

Set xlWrkbk = xlApp.Workbooks.Open("C:\ListMan.xls")
'Set xlWrksht= xlWrkbk.Worksheets("MyLi-Loc")
For iRow = 2 to xlWrkSht.UsedRange.Rows.Count
.......
Next

Really I dont want to open this Excel again and again,thatwhy,I started using import method.Eventhough import method works for me,for selecting all the rows I need to set up for loop and its relative objects...
So again I am using the following command which opens the Excel sheet.

Code:

Set xlWrkbk = xlApp.Workbooks.Open("C:\ListMan.xls").

How to use the Xl sheet rows with out opening the excel sheet?

Any help?
Thanks
