It's not clear what you're trying to do. Do you want to create links to an Excel file? To an attached PDF file? Something else? Based on what do you want to link the text and the file? Do you have a list of all items?
Have a look at this tool I've developed, it lets you do something similar to what you described, I believe: Acrobat -- Create Custom Links from Text
A pop-up preview window is not possible, by the way.
