Yes, If you just want to view a pdf in JMP. Yes, JMP has the capability to upload the file and view it. If you have a pdf file with data that you need to extract, than you might want to use the Internet Option by clicking on File > Internet option and select it either as a web page or text.
That brings you to this pop-up window which ask you for the URL. Copy and paste it there and select the Open As: Webage, Data and Text.
As for Excel, JMP reads all Excel files saved as EXCEL, Text, CSV, etc. Do you know that you can also upload directly JMP by using the JMP-Excel Add-in?
