Need help On 100 Pdfs with minimum 200 pages ..Every Pdf has it own format

The scenario I had 100 pdf documents, Each one consists minimum of 200 pages (maybe differ for every Document ) with Different format.i have to Find the data based on the keyword (which will change for every Pdf document) and fill it in excel. is this possible? can someone help me with this

That is a quite big project. Maybe see if some one is willing to do that for payment.

Also, does every document have those keywords just in different places? If it does, you can do something with regex.

Keywords are not consistent …It changes for every pdf …100 pdfs may be 100 Templates of keywords
