Hi,
if you want to access the cells correctly, follow the Excel object-hierarchy. This example shows you the access to a single cell:
Dim oXLApp As Excel.Application
Dim oXLWs As Excel.Worksheet
dim strCell as String
oXLApp = New Excel.Application()
oXLApp.Workbooks.Open("FileName")
oXLWs = oXLApp.ActiveWorkbook.Sheets(1)
strCell = oXLWs.Range("A1").Value
or
strCell = oXLWs.Range("Name_of_the_cell").Value
To access more than one cell, take a for-next-statement etc. combined with the cells-object.
