今天看见了一个有意思的脚本Python批量实现Word、EXCLE、PPT转PDF文件。

因为我平时word用的比较的多，所以深有体会，具体怎么实现的我们就不讨论了，因为这个去学了也没什么提升，不然也不会当作脚本了。这里我将其放入了pyzjr库中，也方便大家进行调用。

你可以去下载pyzjr:

pip install pyzjr -i https://pypi.tuna.tsinghua.edu.cn/simple

调用方法：

import pyzjr as pz

# 实例化对象
Mpdf = pz.Microsoft2PDF()
# 调用类的方法
Mpdf.Word2Pdf()  # word -> pdf
Mpdf.Excel2Pdf()  # excel -> pdf
Mpdf.PPt2Pdf()  # ppt -> pdf
Mpdf.WEP2Pdf()  # word,excel,ppt -> pdf

上面就是api的调用了，统一会将文件存放在目标文件夹下新建的名为pdf文件夹中。

pyzjr中的源码：

import win32com.client, gc, os

class Microsoft2PDF():
    """Convert Microsoft Office documents (Word, Excel, PowerPoint) to PDF format"""
    def __init__(self,filePath = ""):
        """
        :param filePath: 如果默认是空字符,就默认当前路径
        """

        self.words = []
        self.ppts = []
        self.excels = []

        if filePath == "":
            filePath = os.getcwd()
        folder = filePath + '\\pdf\\'
        self.folder = CreateFolder(folder,debug=False)

        self.filePath = filePath
        for i in os.listdir(self.filePath):
