Link 'Excel Object in Word' to Excel

I have a Word document which contains several embedded Excel objects which is
sent to 600 clients. The clients complete the data collection in the word
document and send back. We have a Excel worksheet for each client that uses
the data in the embedded Excel objects. Is there a way to "link" or transfer
the data in the 'Excel Object in Word' to the appropriate cells in the Excel
worksheet?

Because each Word document is customized for each client using Mail Merge
and an Access database, and because there is much verbage and many sections
in the document sent to the client, sending an Excel worksheet to the client
is not an option.

I'd prefer some sort of direct link (but I have not been successful at
that). I'm OK with VBA so that is an option.

Any ideas?

Thank you in advance,
Robin
