Manage form data files
You can move the answers on a PDF form to and from other file formats that preserve all the data in much less space than a full PDF. Import form data
In some workflow scenarios, individuals submit filled-in forms as data-only files rather than as complete PDF files. These files are not PDFs, but use another file format, such as FDF or XML. You can view the data submitted by an individual recipient in the context of the PDF by opening the original file and importing the information in the data file.
1In Acrobat, open the PDF form into which you want to import data.
2Choose Forms > Clear Form.
Note: When you import data from another file into a PDF form, the imported data replaces any information that appeared previously in the individual form fields. However, if the imported data file contains one or more blank form fields, importing will not clear the original data.
3Choose Forms > Manage Form Data > Import Data.
4In the Select File Containing Form Data dialog box, select a format in File Of Type corresponding to the data file you want to import. Then locate and select that file, and click Select.
Note: Some formats are available only for specific types of PDF forms, depending on the application used to create the form, such as Acrobat or Designer ES. Data you import from a text file (.txt) must be formatted in tab-delimited rows that form columns.
