You can access the data  of any cell  using following line  of code.

excel.workbooks.range("A2").text or excel.workbooks.range("A2").value

Also if you wnt to write something inside the cell then use following line of
code
excel.workbooks.range("A3").formular1c1 = "Write text  Here"

I hope this will help  u lot. If not then let me know what actually u wnt to do.
