jPDF Fields is a Java library, specifically designed to be used by programmers, from which you can, by calling the functions through source code, interact with the PDF forms, allowing you to import or export from one document to another, as well as obtain the value of the fields of said form.
You can export to other formats, such as FDF, XFDF and XDP, the values of the fields that you get from the functions with which jPDF Fields is equipped. The functions will also allow you to load PDF documents, access the network units, read XFA formats, delete the content of the original PDF form once you have obtained the data, and so on.
From the functions of jPDF Fields you can also restore all the values of the default fields of the PDF or, if you prefer, save it with a new name.
You can free download jPDF Fields 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
