There are websites that try to take the data out of an PDF and insert it into Excel for you (like smallpdf), but i dont realy think they will help you that much.
An other way to import i do not know about. So what is left for you, is copy and paste, split by delimiter and you're done.
I know that this doesn't really help, but maybe there is an other way. Where do you get that data from? Maybe you can grab the data before you make a PDF out of it?
