Python script to convert a bunch of Microsoft Powerpoint files (.ppt or .pptx) to PDF
Python script to convert a bunch of Microsoft Powerpoint files (.ppt or .pptx) to PDF. Powerpoint must be installed on the machine for this to work.
python batch_ppt_to_pdf.py
Tested with Python 3 on Windows
When I run your code, I meet an error:
Traceback (most recent call last):
File "convert.py", line 24, in <module>
powerpoint = init_powerpoint()
File "convert.py", line 5, in init_powerpoint
powerpoint = comtypes.client.CreateObject("Powerpoint.Application")
File "D:\software\Anaconda\envs\MCM\lib\site-packages\comtypes\client\__init__.py", line 250, in CreateObject
return _manage(obj, clsid, interface=interface)
File "D:\software\Anaconda\envs\MCM\lib\site-packages\comtypes\client\__init__.py", line 188, in _manage
obj = GetBestInterface(obj)
File "D:\software\Anaconda\envs\MCM\lib\site-packages\comtypes\client\__init__.py", line 112, in GetBestInterface
interface = getattr(mod, itf_name)
AttributeError: module 'comtypes.gen.PowerPoint' has no attribute '_Application'
The solution to this problem is change the method init_powerpoint to:
def init_powerpoint():
powerpoint = win32com.client.DispatchEx("Powerpoint.Application")
return powerpoint
Python version: 3.6.5 ，the error message '无效的类字符串' means 'invalid class string', my pc does not install Microsoft office.I use LibreOffice, does this reason cause the error?
that is all, thank you :)
Shouldn't the second last line in the below be
fullpath = os.path.join(folder, pptfile)
not cwd?
def convert_files_in_folder(powerpoint, folder):
files = os.listdir(folder)
pptfiles = [f for f in files if f.endswith((".ppt", ".pptx"))]
for pptfile in pptfiles:
fullpath = os.path.join(cwd, pptfile)
ppt_to_pdf(powerpoint, fullpath, fullpath)
