Batch Processing of Acrobat Fillable Forms to Excel Spreadsheet

It has been many years since I have had to do this. I will be sending a pre-publication book reservation form to more than 500 who have indicated interest in my forthcoming book. Some may no longer be interested and others may want multiple copies. So... I will create a fillable form that I will email to the list. Respondents will return the completed form by email.  Can I batch-process those PDFs which will all have the same filename and could come in in large numbers at a time? I will use the resulting spreadsheet to bath-generate PayPal invoices.

Thanks in advance, Lauren P.
