Do you have Adobe Acrobat? If so, select "Tools>Forms>More Form Options>Merge Data Files into Spreadsheets". This way, you can select all PDF form files, and you can export everything into one spreadsheet.
If you want to do this on a per-file basis, you can use the same menu, but then use "Export Data". You would have to do this on a per-file basis. You can however automate this by writing JavaScript and then use the Doc.exportAsText() method to write out a CSV file that can be loaded in Excel.
