Today I saw an interesting script Python to convert Word, EXCLE, PPT to PDF files in batches .
Because I usually use word a lot, so I have a deep understanding. We won’t discuss how to realize it specifically, because there is no improvement after learning this, otherwise it will not be used as a script. Here I put it in the pyzjr library, which is also convenient for everyone to call.
You can go to download pyzjr:
pip install pyzjr -i https://pypi.tuna.tsinghua.edu.cn/simpleCalling method:
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 -> pdfThe above is the call of the api, and the unified file will be stored in the newly created folder named pdf under the target folder.
Source code in pyzjr:

This is the information printed by the console. We can find that when calling WEP2Pdf, if there is no word file in the current folder, the conversion can continue.
