I am trying to do something similar, but I cannot figure out how to close the excel instance from task manager. Any assistance? code snippet below

Public Sub Main()

'

Dim objExcel As Object

objExcel = CreateObject("Excel.Application")

objExcel.Workbooks.Open("*.xls")

objExcel.displayalerts = False

objExcel.Sheets("*").Select()

objExcel.rows("2:50000").delete()

objExcel.Workbooks(1).Save()

objExcel.Workbooks.Close(False)

objExcel.displayalerts = True

objExcel = Nothing
