两行Python代码实现pdf转word功能

目录

• 一、安装依赖包
• 二、pdf转word
• 2.1 代码实现
• 2.2 pdf内容
• 2.3 转换后的word
• 补充

一、安装依赖包

pip install --index https://pypi.mirrors.ustc.edu.cn/simple/ python-office

二、pdf转word

2.1 代码实现

import office
office.pdf.pdf2docx(file_path = 'test.pdf')

运行过程如下：

[INFO] [2/4] Analyzing document...

2.2 pdf内容

2.3 转换后的word

由上可见，效果还不错。

补充

除了上文的办法，小编还为大家整理了更多Python实现的PDF转Word方法，需要的可以参考一下

方法一：

import os
from configparser import ConfigParser
from io import StringIO
from io import open
from concurrent.futures import ProcessPoolExecutor

from pdfminer.pdfinterp import PDFResourceManager
from pdfminer.pdfinterp import process_pdf
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from docx import Document


def read_from_pdf(file_path):
    with open(file_path, 'rb') as file:
        resource_manager = PDFResourceManager()
        return_str = StringIO()
        lap_params = LAParams()

        device = TextConverter(
            resource_manager, return_str, laparams=lap_params)
        process_pdf(resource_manager, device, file)
        device.close()

        content = return_str.getvalue()
        return_str.close()
        return content


def save_text_to_word(content, file_path):
    doc = Document()
    for line in content.split('\n'):
        paragraph = doc.add_paragraph()
        paragraph.add_run(remove_control_characters(line))
    doc.save(file_path)


def remove_control_characters(content):
    mpa = dict.fromkeys(range(32))
    return content.translate(mpa)


def pdf_to_word(pdf_file_path, word_file_path):
    content = read_from_pdf(pdf_file_path)
    save_text_to_word(content, word_file_path)


def main():
    config_parser = ConfigParser()
    config_parser.read('config.cfg')
    config = config_parser['default']

    tasks = []
    with ProcessPoolExecutor(max_workers=int(config['max_worker'])) as executor:
        for file in os.listdir(config['pdf_folder']):
            extension_name = os.path.splitext(file)[1]
            if extension_name != '.pdf':
                continue
            file_name = os.path.splitext(file)[0]
            pdf_file = config['pdf_folder'] + '/' + file
            word_file = config['word_folder'] + '/' + file_name + '.docx'
            print('正在处理: ', file)
            result = executor.submit(pdf_to_word, pdf_file, word_file)
            tasks.append(result)
    while True:
        exit_flag = True
        for task in tasks:
            if not task.done():
                exit_flag = False
        if exit_flag:
            print('完成')
            exit(0)


if __name__ == '__main__':
    main()
