PDF Form Filling Guide

This guide covers how to fill PDF forms programmatically.

Prerequisites

Install required packages:

pip install pypdf pdfrw

Basic Form Filling

from pypdf import PdfReader, PdfWriter

def fill_form(input_path, output_path, field_data):
    reader = PdfReader(input_path)
    writer = PdfWriter()
    
    # Clone the original PDF
    writer.clone_document_from_reader(reader)
    
    # Fill form fields
    for page in writer.pages:
        writer.update_page_form_field_values(page, field_data)
    
    # Save the filled PDF
    with open(output_path, "wb") as f:
        writer.write(f)

Supported Field Types

  • Text fields
  • Checkboxes
  • Radio buttons
  • Dropdown lists

Tips

  1. Use scripts/analyze_form.py to discover available fields
  2. Field names are case-sensitive
  3. Always verify output after filling
