Python实现Word、Excel、PPT批量转为PDF

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：

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.flagW = self.flagE = self.flagP = 1
        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):
            if i.endswith(('.doc', 'docx')):
                self.words.append(i)

 这里我对原先博主的代码进行了一定的优化，使其可供我们调用。

这是控制台打印出来的信息，我们可以发现在调用WEP2Pdf时，如果当前文件夹中没有word的文件也能继续去转换。
