I dont think you can convert a PDF into EXCEL.
Normally is comer delimited.
If you can copy and paste the date into a text file you might be half way.
Adobe does an Editable version of PDF but i'm sure this depends upon how its been saved in the first place.
Try to think of it like this, your PDF document may as well as be a image for the way it handles text. You cant export values if its an image.
No idea on freeware. sorry.
