Python 3 Flask Project to Export Multiple PDF Documents to Word Docx Files Using pdf2docx Library in Browser

Welcome folks today in this blog post we will be using the pdf2docx library inside the flask application to bulk process the pdf documents to docx files in browser using python. All the full source code of the application is shown below.

Get Started

In order to get started you need to install the below libraries using the pip command as shown below

pip install flask

pip install pdf2docx

And after that you need to make the app.py file and copy paste the following code

app.py

import os
from flask import Flask, render_template, request, send_file
from werkzeug.utils import secure_filename
from pdf2docx import Converter
import zipfile

app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = 'uploads'


@app.route('/')
def index():
    return render_template('index.html')


@app.route('/convert', methods=['POST'])
def convert():
    # Get the uploaded PDF files
    pdf_files = request.files.getlist('pdf_files')

    # Create a temporary folder to store the converted DOCX files
    temp_folder = os.path.join(app.config['UPLOAD_FOLDER'], 'temp')
    os.makedirs(temp_folder, exist_ok=True)

    # Convert each PDF file to DOCX
    docx_files = []
    for pdf_file in pdf_files:
        if pdf_file.filename != '':
            # Save the PDF file
            filename = secure_filename(pdf_file.filename)
            pdf_path = os.path.join(temp_folder, filename)
            pdf_file.save(pdf_path)

            # Convert PDF to DOCX
            docx_path = os.path.join(temp_folder, os.path.splitext(filename)[0] + '.docx')
            converter = Converter(pdf_path)
            converter.convert(docx_path)
            converter.close()

            docx_files.append(docx_path)

    # Create a ZIP archive of the converted DOCX files
    zip_path = os.path.join(app.config['UPLOAD_FOLDER'], 'converted_files.zip')
    with zipfile.ZipFile(zip_path, 'w') as zip_file:
        for docx_file in docx_files:
            zip_file.write(docx_file, os.path.basename(docx_file))

    # Send the ZIP file for download
    return send_file(zip_path, as_attachment=True)


if __name__ == '__main__':
    app.run(debug=True)

import os

from flask import Flask, render_template, request, send_file

from werkzeug.utils import secure_filename

from pdf2docx import Converter

import zipfile

app = Flask(__name__)

app.config['UPLOAD_FOLDER'] = 'uploads'

@app.route('/')

def index():

return render_template('index.html')

@app.route('/convert', methods=['POST'])

def convert():

# Get the uploaded PDF files

pdf_files = request.files.getlist('pdf_files')

# Create a temporary folder to store the converted DOCX files

temp_folder = os.path.join(app.config['UPLOAD_FOLDER'], 'temp')

os.makedirs(temp_folder, exist_ok=True)

# Convert each PDF file to DOCX

docx_files = []

for pdf_file in pdf_files:

if pdf_file.filename != '':

# Save the PDF file

filename = secure_filename(pdf_file.filename)

pdf_path = os.path.join(temp_folder, filename)

pdf_file.save(pdf_path)

# Convert PDF to DOCX

docx_path = os.path.join(temp_folder, os.path.splitext(filename)[0] + '.docx')

converter = Converter(pdf_path)

converter.convert(docx_path)

converter.close()

docx_files.append(docx_path)

# Create a ZIP archive of the converted DOCX files

zip_path = os.path.join(app.config['UPLOAD_FOLDER'], 'converted_files.zip')

with zipfile.ZipFile(zip_path, 'w') as zip_file:

for docx_file in docx_files:

zip_file.write(docx_file, os.path.basename(docx_file))

# Send the ZIP file for download

return send_file(zip_path, as_attachment=True)

if __name__ == '__main__':

app.run(debug=True)

As you can see we have defined all the get and post routes for exporting the pdf files to docx files using the pdf2docx library which we have imported at the top and then we are loading the index.html template now we need to define this as shown below

templates/index.html

<!DOCTYPE html>
<html>
<head>
    <title>PDF to DOCX Conversion</title>
</head>
<body>
    <h1>PDF to DOCX Conversion</h1>
    <form action="/convert" method="post" enctype="multipart/form-data">
        <input type="file" name="pdf_files" multiple accept=".pdf">
        <input type="submit" value="Convert">
    </form>
</body>
</html>

<!DOCTYPE html>

<html>

<head>

<title>PDF to DOCX Conversion</title>

</head>

<body>

<h1>PDF to DOCX Conversion</h1>

</form>

</body>

</html>
