Transfer/hyperlink Word field codes to Access db or Excel wks

We use a lot of Word docs with field code inserts (“gray boxes”) for customer/internal correspondence, becasue they’re “friendly”. All sorts of info about imbedding Excel wks INTO Word docs; but nothing about transfering Word info in these designated fields (and they DO have unique addresses, e.g., TextBox11, etc.), INTO a specific Excel cell or Access field.

Is this possible? I’m sure it must be; but I can find no “how-to” info at MS.com or elsewhere. VBA dialogue boxes, maybe?
