There’s no easy way I know of but having had to do that with a PDF report of lots of data (12 Pages), I had to select all tabular data on each page, copy it and paste into a text file. I then removed all commas before doing a find and replace on spaces and replacing them with commas. Finally I saved the file as a csv file and imported it into my spreadsheet. Even after all of that I spent a fair amount time aligning the data into proper columns. The previous assumes that PDF is text-based. If it’s image-based you need to OCR it first before doing what wrote. Then is it essential to carefully proofread everything to make sure the OCR didn’t screw up some numbers.
I really hope I got any of this 100% right.
