Is it possible to extract data from multiple vendors within the same PDF file? We have some receipts for different grocery stores, so some may be formatted differently than others. Also, some receipts are 1 per page, but some online purchase receipts may be several pages per receipt. We have all receipts scanned in the same PDF file - will we be able to extract data from all of these if they're in 1 file? Or would we have to separate each receipt into a separate PDF file? Or would system be able to machine learn where 1 receipt begins & ends?
