Charles' links don't appear to be directly relevant to your request if you have already created the form.
To me, your question appears to be asking how to extract/collate the responses from multiple forms into a single Excel worksheet. Unfortunately, this is not a simple request and it will likely require considerable effort to get this setup. It also varies with how the Word form was created and whether it uses Content Controls or Form Fields for the data fields.
If that is the case, something like this may be more relevant to you.
