Find highlighted text in PDF and Locate this text in Excel


I have a PDF and an excel file, which contain similar information. The data set is quite large. I have some items in the pdf that I want to find in the excel docuemnt (text). I hope to automate this so that I do not need to search for these items. What is the best way to locate select items in the pdf and search for & mark these items off in excel?

Thank you
