One of the most annoying things about gathering data is that sometimes it is shown in PDF format. As you know the process of copy and paste data from PDF to EXCEL or STATA can be very painful.
Tabula, came some time ago, is a useful piece of free software to get the data tables out of countless PDF files.
It's really is simple to use. Load a PDF file into Tabula, which runs on your computer, highlight the table to extract, and the program does the rest.
