Python docx2pdf AttributeError: Open.SaveAs

Question

I am trying to convert a docx file to pdf using the docx2pdf library, using the following code:

from docx2pdf import convert

convert("generated.docx")

As written here. But I have an error:

Traceback (most recent call last):
  File "c:\Users\user\Desktop\folder\script.py", line 29, in <module>
    convert("generated.docx")
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\site-packages\docx2pdf-0.1.8-py3.10.egg\docx2pdf\__init__.py", line 106, in convert
    return windows(paths, keep_active)
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\site-packages\docx2pdf-0.1.8-py3.10.egg\docx2pdf\__init__.py", line 33, in windows
    doc.SaveAs(str(pdf_filepath), FileFormat=wdFormatPDF)
  File "C:\Users\user\AppData\Local\Programs\Python\Python310\lib\site-packages\win32com\client\dynamic.py", line 639, in __getattr__
    raise AttributeError("%s.%s" % (self._username_, attr))
AttributeError: Open.SaveAs

I also tried converting with comtypes and pywin32, but I get the same error. I take code from here.

import sys
import comtypes.client

wdFormatPDF = 17

in_file = os.path.abspath("generated.docx")
out_file = os.path.abspath("generated.pdf")

word = comtypes.client.CreateObject('Word.Application')
doc = word.Documents.Open(in_file)
doc.SaveAs(out_file, FileFormat=wdFormatPDF)
doc.Close()
word.Quit()
---------------------------------
Traceback (most recent call last):
  File "c:\Users\user\Desktop\folder\script.py", line 45, in <module>
    doc.SaveAs(out_file, FileFormat=wdFormatPDF)
_ctypes.COMError: (-2147418111, 'Call was rejected by callee.', (None, None, None, 0, None))

import sys
import win32com.client

wdFormatPDF = 17

in_file = os.path.abspath("generated.docx")
out_file = os.path.abspath("generated.pdf")

word = win32com.client.Dispatch('Word.Application')
doc = word.Documents.Open(in_file)
doc.SaveAs(out_file, FileFormat=wdFormatPDF)
doc.Close()
word.Quit()

AttributeError: Open.SaveAs

How can I fix this error? Or please suggest another way to convert docx to pdf. Thank you in advance

Answer 1

from docx2pdf import convert

inputFile = "document.docx"
outputFile = "document2.pdf"
file = open(outputFile, "w")
file.close()

convert(inputFile, outputFile)

You should create the output file first

Answer 2

change:

word = win32com.client.Dispatch('Word.Application')

to

import pythoncom
word = win32com.client.Dispatch('Word.Application', pythoncom.CoInitialize())
