Chapter 7 – Data Import & Export
Data in PDFs can be imported and exported to FDF files. FDF, namely Forms Data Format, a file
format used for interactive form data, is used when submitting form data to a server, receiving
the response, and incorporating it into the interactive form. It can also be used to export form
data to stand-alone files that can be stored, transmitted electronically, and imported back into
the corresponding PDF interactive form. In addition, FDF can be used to define a container for
annotations that are separate from the PDF document to which they apply. Or sometimes, when
you have to send a PDF file to others but do not want them to see your comments and form data,
you may export all the data with this function, clear the file and send it to others. In this way, all
the data you added can be removed.
There are two kinds of data that can be imported and exported: comment data and form data.
You can also send the comment data or form data as FDF file to your clients or friends. The FDF
does not only save all the data contents of the PDF documents, but also remembers their specific
positions and status in the files.
Importing & Exporting Comments Data
This feature is especially useful for PDF reviewing. When you receive an email invitation to a PDF
review, the invitation typically includes the PDF as an attachment or provides a URL to the PDF.
Alternatively, you may receive a Form Data Format (FDF) attachment. When opened, an FDF file
configures your review settings and opens the PDF in a web browser. At this moment, you need
to know how to import the comment data from the FDF file. Similarly, you may export comment
data and send them as a FDF file to the other participants.
