Export to JSON

JSON is a widely used data format that enables seamless exchange between applications and services. In this example, the Form object from the aspose.pdf.facades module is used to bind a PDF file and export its form field values into a readable JSON structure.

1. Initialize pdf_facades.Form() to work with form fields.
2. Use ‘bind_pdf()’ to attach the source PDF document.
3. Create a writable stream using ‘FileIO()’.
4. Call ’export_json()’ to extract form field values and save them in formatted JSON.

from io import FileIO
import sys
from os import path
import aspose.pdf as ap
import aspose.pdf.facades as pdf_facades

sys.path.append(path.join(path.dirname(__file__), ".."))

from config import set_license, initialize_data_dir


# Export Data to JSON
def export_form_to_json(infile, outfile):
    """Export PDF form field values to JSON file."""
    # Create Form object
    form = pdf_facades.Form()

    # Bind PDF document
    form.bind_pdf(infile)

    # Create JSON file stream
    with FileIO(outfile, "w") as json_stream:
        # Export form field values to JSON
        form.export_json(json_stream, indented=True)
