PDF Form Processor

Process fillable PDF forms: analyze fields, fill values, validate output.

Capabilities

  • Extract form field information
  • Fill form fields programmatically
  • Validate field mappings
  • Verify output documents

Quick Start

Extract Fields

python scripts/analyze_form.py input.pdf > fields.json

Fill Form

python scripts/fill_form.py input.pdf fields.json output.pdf

Workflow

Step 1: Analyze Form

Run analysis script to extract fields:

python scripts/analyze_form.py form.pdf

Output format:

{
  "field_name": {"type": "text", "x": 100, "y": 200},
  "signature": {"type": "sig", "x": 150, "y": 500}
}

Step 2: Create Field Mapping

Edit fields.json to add values:

{
  "field_name": {
    "type": "text",
    "value": "John Doe"
  }
}

Step 3: Validate Mapping

Check for errors before filling:

python scripts/validate_fields.py fields.json
# Returns: "OK" or lists issues

Step 4: Fill Form

Apply values to PDF:

python scripts/fill_form.py input.pdf fields.json output.pdf

Step 5: Verify Output

Check filled document:

python scripts/verify_output.py output.pdf

If verification fails, return to Step 2.
