Python Script for Batch Processing

import os
from docx2pdf import convert

def convert_folder(input_dir, output_dir):
    os.makedirs(output_dir, exist_ok=True)
    for file in os.listdir(input_dir):
        if file.endswith('.docx'):
            input_path = os.path.join(input_dir, file)
            output_path = os.path.join(output_dir, file.replace('.docx', '.pdf'))
            convert(input_path, output_path)
