AcroForms can keep form field values in external stand-alone files containing key:value pairs. The external files may use Forms Data Format (FDF) and XML Forms Data Format (XFDF) files. The usage rights (UR) signatures define rights for import form data files in FDF, XFDF and text (CSV/TSV) formats, and export form data files in FDF and XFDF formats.
The Forms Data Format can be used when submitting form data to a server, receiving the response, and incorporating into the interactive form. It can also be used to export form data to stand-alone files that can be imported back into the corresponding PDF interactive form.
After downloading PDF files with form data, many people are troubled with how to extract Form Data from PDF to CSV for reusing as below.
Q: Are there software packages to extract data from multiple Acrobat (pdf) forms?
I may set up some editable Acrobat form documents that are filled out by up to several hundred people to collect some data about them. I’m wondering if there are any software packages out there that will extract data from the fields in these hundreds of Acrobat forms and either write the data to a single file or write the data diretly to a MySQL database?
Luckily, a friend of mine recommended me a PDF Form Data Extractor which he tried very great. I download the free trial and found it’s very easy to use, and can batch extract form data from PDF files at one time. Then you can save the exported form data as CSV or XML files. Then I bought it without any hesitating. If you have the same problem with me, maybe you can try it. Maybe you also want to how to extract images from PDF files.
