- Product

- Device & OS
- not provided
- Scenario
- Applying exported FDF form data to a blank or existing interactive PDF form to restore or fill in the information.
- Observed behavior
- The user seeks the correct commands and procedures within Acrobat Pro DC to successfully merge the FDF data into the open PDF document.
Ensure you have the correct, compatible PDF form open before importing the FDF file. The field names embedded in the FDF data must perfectly match the form fields in the PDF document to populate successfully.
Use the Built-in 'Import Data' Command
This is the standard and most reliable method to merge FDF data into your active PDF form using Acrobat's Prepare Form tool.
Acrobat Pro DC features a dedicated data management tool within the Prepare Form workspace that precisely maps FDF data to the corresponding form fields.
Launch Adobe Acrobat Pro DC and open the specific PDF form that matches your FDF data.
Navigate to the right-hand tool pane and click on 'Prepare Form'. Alternatively, you can find this under the 'Tools' menu.
In the right-hand panel, click on 'More' (often represented by a wrench or gear icon). Select 'Import Data' from the drop-down menu.
In the file browser dialog, locate your saved FDF file, select it, and click 'Open'. The data will instantly populate the matching fields in your PDF form.

Use the Drag-and-Drop Method
A quick and effortless alternative if you already have the PDF form open and the FDF file readily accessible on your desktop or file explorer.
Edit and Fill PDF Forms Easily with WPS Office
While Adobe Acrobat Pro DC requires a paid subscription for advanced form management, WPS Office provides a lightweight, highly compatible, and affordable alternative. It allows you to seamlessly read, edit, and fill PDF documents alongside Word, Excel, and PowerPoint files.
- 1. Download and Install: Get WPS Office for free from the official website and complete the quick installation process.
- 2. Open your PDF: Launch WPS Office, click on 'Open', and select your PDF form.
- 3. Fill and Edit: Use the built-in PDF tools to simply click on interactive form fields and seamlessly enter your data.

Frequently Asked Questions
What exactly is an FDF file?
An FDF (Form Data Format) file is a plain text file that contains only the data entered into a PDF form, rather than the complete PDF document itself. It is used to save form data compactly and can be imported back into a blank version of the same PDF form to restore the entered information.
Why didn't my PDF form populate when I imported the FDF file?
This almost always occurs because the field names in the FDF file do not perfectly match the field names in the currently open PDF form. To resolve this, ensure you are importing the FDF data into the exact same PDF form version from which it was originally exported.
Can I import FDF files using Adobe Acrobat Reader instead of Pro DC?
By default, importing FDF data via the menu requires Adobe Acrobat Pro or Standard. However, if the creator of the PDF form added specific document rights or customized JavaScript (like a custom menu item or toolbar button), it is possible to import FDF files using the free Reader version.
