- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Extracting form field data and verifying the underlying export values assigned to specific interactive form controls.
- Observed behavior
- Requires a scripted method to loop through all document fields and print the names and export values exclusively for checkbox and radio button types.
Ensure your PDF form contains the checkboxes or radio buttons you want to query, and that you have permission to access the JavaScript Debugger console in your PDF application.
Use Acrobat JavaScript to Extract Export Values
Run a short JavaScript snippet in the Acrobat console to loop through all document fields and print the export values of checkboxes and radio buttons.
Adobe Acrobat includes a built-in JavaScript engine that allows you to interact with PDF elements programmatically. By using a simple loop, you can extract the exact export values assigned to interactive fields without checking them manually one by one.
Launch Adobe Acrobat and open the PDF document containing the interactive form fields.
Open the JavaScript Debugger by pressing Ctrl + J (on Windows) or Cmd + J (on Mac).
Copy and paste the following code into the console window: `for (var i = 0; i < this.numFields; i++) { var f = this.getField(this.getNthFieldName(i)); if (f == null) continue; if (f.type == "checkbox" || f.type == "radiobutton") console.println(f.name + ": " + f.exportValues); }`
Highlight the code and press Ctrl + Enter (or Enter on the numeric keypad) to run it. The console will print out the field names and their respective export values.

Can I extract PDF form data without using JavaScript?
Yes. Most professional PDF editors, including WPS Office and Adobe Acrobat, feature built-in 'Export Form Data' functionalities that allow you to save the contents of filled forms directly to formats like FDF, CSV, or XML without needing to write code.
How do I change the export value of a radio button?
