前言： 【[亲妈版]Python批量将PPT转换为PPTX】本文基于Python语言环境实现，以及vsCode工具开发完成，可以支持ppt转pptx 或 pptx转ppt pdf png 等格式。
正式开发： 1、安装reportlab模块

#安装reportlab模块 pip3 install reportlab

2、安装win32com模块
第一种：

pip3 install pywin32

第二种：

python -m pip install --upgrade pip -i https://pypi.douban.com/simple

3、创建pptToPptx.py

import os import loggingfrom reportlab.lib.pagesizes import A4, landscape from reportlab.pdfgen import canvas import win32com.clientlogger = logging.getLogger('Sun') logging.basicConfig(level=20, # format="[%(name)s][%(levelname)s][%(asctime)s] %(message)s", format="[%(levelname)s][%(asctime)s] %(message)s", datefmt='%Y-%m-%d %H:%M:%S'# 注意月份和天数不要搞乱了，这里的格式化符与time模块相同 )def getFiles(dir, suffix, ifsubDir=True):# 查找根目录，文件后缀 res = [] for root, directory, files in os.walk(dir):# =>当前根,根下目录,目录下的文件 for filename in files: name, suf = os.path.splitext(filename)# =>文件名,文件后缀 if suf.upper() == suffix.upper(): res.append(os.path.join(root, filename))# =>吧一串字符串组合成路径 if False is ifsubDir: break return resclass pptTrans: def __init__(self, infoDict, filePath): self.infoDict = infoDict self.filePath = filePath self.powerpoint = Noneself.init_powerpoint() self.convert_files_in_folder(self.filePath) self.quit() os.system('pause')def quit(self): if None is not self.powerpoint: self.powerpoint.Quit()def init_powerpoint(self): try: self.powerpoint = win32com.client.DispatchEx("Powerpoint.Application") self.powerpoint.Visible = 2 except Exception as e: logger.error(str(e))def ppt_trans(self, inputFileName): #

4、运行Py文件
第一种：cmd运行 找到文件目录输入：python pptToPptx.py
第二种：VSCode软件，配置python环境，运行 5、选择序号，输入文件夹路径即可。
6、到所输入文件夹路径下的pptx文件下查看所有转换成功的文件
7、完成，有帮助，记得点赞，感谢！
