Download form Field Data

I use my MS Access database to populate client pdf fforms for signature.  It works nicely, but my hard drive failed, and I lost client data in the MS access DB for the past month.  There is, however, client data in the pdf documents I could use to repopulate my MS DB.  I see there is a  "download form field data" button and I can get a nice csv file for each document.  My question is whether I could download a group of file data to just one exel file.
