Not sure about Word, but if it were me and I had the data in Excel, I would import it into Access then link to the SQL table, create an append query that would take the Excel data you import and append it to the Linked SQL table.
Better yet, if you got rid of the word document all together, you could have the user type the data into a Excel spreadsheet, link the spreadsheet, link the SQL table then do the append every time you open the database.
