With AlgoDocs' advanced extracting rules you can process PDF files of any scenarios automatically. Your PDF files can contain several independent documents and as a result you would like to get extracted data for each independent document inside that long combined PDF file. Therefore, AlgoDocs splits combined PDF files automatically right after you import them. So, there are no manual steps that you need to do before importing your combined PDF files to AlgoDocs.
