If you don't have SP2 applied to MS Office then you can use the linked
tables method. Use the linked table manager to browse to your Excel file
and then use it within Access as if it was a linked table.
If you do have SP2 applied to MS Office then the linked table method is
read-only and you will have to use Office Automation instead. This is
essentially setting a library reference to Excel from within an Access code
module window and using VBA code to control your Excel spreadsheet from
within Access. What's in the code will of course depend upon what you want
to do but a good starting point might be to Google for "Office Automation"
to get some background.
I learned how to use automation by reading this book, "Integrating Excel and
Access":

That's a genuine recommendation, I'm not affiliated with the authors or
publishers in any way.
Good luck.
