Retrieve Excel fields from a PDF Form

You need to better explain how you want this to work. Do you want to extract the data from the same file each time, or from various files?

Will these files be open in Acrobat?

Generally speaking, Acrobat is not the right tool for this kind of task. I would recommend using a stand-alone command-line tool that extracts the data from the PDF to an Excel file (or a CSV file, which is much easier), and then use a Scheduled Task to run it in intervals.

I have just developed a tool that does that for a client of mine so if you're interested in discussing it privately feel free to contact me at try6767 at gmail.com.
