Why Acrobat Import Form Data Accepts Only FDF Files (and How to Fix)
Question details
The user is unable to import form data in formats like XFDF or XML because Acrobat's Import Form Data dialog restricts the selection to FDF files only.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Importing external form data (such as XFDF or XML) into an existing PDF form.
- Observed behavior
- The import dialog only displays FDF as an available format, preventing the user from selecting other supported data formats like XFDF, HTML, and XML.
Before troubleshooting, verify whether your PDF form is a standard AcroForm or an XFA form created in Adobe LiveCycle Designer, as XFA forms have strict data import limitations.
Verify the PDF Form Type and Adjust Import Workflow
Determine if you are using an AcroForm or an XFA form, as standard AcroForms support a wider range of import formats.
Standard AcroForms support data imports in FDF, XFDF, HTML, and XML formats. However, XFA forms created with LiveCycle Designer often restrict import formats based on how the form was structurally bound.
If Acrobat only shows FDF in the import dialog, you are likely dealing with an XFA form or an outdated Acrobat version.
Open the PDF form in Adobe Acrobat, go to File > Properties, and check the Description tab to see if the Application or PDF Producer mentions LiveCycle Designer (indicating an XFA form).
When opening the Import Form Data dialog via Prepare Form > More > Import Data, click the file type dropdown menu at the bottom right. If other formats aren't listed, the form architecture does not support them.
If you strictly need to import XFDF or XML data, you may need to recreate or print the XFA form to a flat PDF, then use the Prepare Form tool in Acrobat to convert it into a standard AcroForm.

Easily Edit and Manage PDF Forms with WPS Office

- 2. Open your PDF Form: Drag and drop your PDF form into the WPS interface, or go to the Menu and select Open to browse for your file.
- 3. Fill and Edit: Use the Form tab to fill out interactive fields, edit text, or add electronic signatures effortlessly.
- 4. Save and Export: Once the data is entered, save your filled PDF or export it directly without worrying about restrictive data import formats.

Frequently Asked Questions
What is the difference between AcroForms and XFA forms?
AcroForms are the standard PDF forms that natively support a wide range of data formats like FDF, XFDF, and XML. XFA forms (XML Forms Architecture) are created using Adobe LiveCycle Designer and typically have strict structural bindings that limit how data can be imported or exported.
Can I force Adobe Acrobat to import XML into an XFA form?
If the XFA form was not explicitly designed and bound to accept raw XML imports, the Import Form Data dialog will restrict your options to FDF or specific data bindings. You must modify the original form template in LiveCycle Designer to change this.
What formats are supported for exporting form data in Acrobat?
For standard AcroForms, Acrobat allows you to export form data as FDF, XFDF, XML, and HTML. You can access this feature by navigating to Prepare Form > More > Export Data.
