I'am tasked with converting tons of .doc files to .pdf. And the only way my supervisor wants me to do this is through MSWord 2010. I know I should be able to automate this with python COM automation. Only problem is I dont know how and where to start. I tried searching for some tutorials but was not able to find any (May be I might have, but I don't know what I'm looking for).
Right now I'm reading through this. Dont know how useful this is going to be.
A simple example using comtypes, converting a single file, input and output filenames given as commandline arguments:
import sys
import os
import comtypes.client
wdFormatPDF = 17
in_file = os.path.abspath(sys.argv[1])
out_file = os.path.abspath(sys.argv[2])
word = comtypes.client.CreateObject('Word.Application')
doc = word.Documents.Open(in_file)
doc.SaveAs(out_file, FileFormat=wdFormatPDF)
doc.Close()
word.Quit()
You could also use pywin32, which would be the same except for:
import win32com.client
and then:
word = win32com.client.Dispatch('Word.Application')
You can use the docx2pdf python package to bulk convert docx to pdf. It can be used as both a CLI and a python library. It requires Microsoft Office to be installed and uses COM on Windows and AppleScript (JXA) on macOS.
from docx2pdf import convert
convert("input.docx")
convert("input.docx", "output.pdf")
convert("my_docx_folder/")
pip install docx2pdf
docx2pdf input.docx output.pdf
Disclaimer: I wrote the docx2pdf package. https://github.com/AlJohri/docx2pdf
I have tested many solutions but no one of them works efficiently on Linux distribution.
I recommend this solution :
import sys
import subprocess
import re
def convert_to(folder, source, timeout=None):
args = [libreoffice_exec(), '--headless', '--convert-to', 'pdf', '--outdir', folder, source]
process = subprocess.run(args, stdout=subprocess.PIPE, stderr=subprocess.PIPE, timeout=timeout)
filename = re.search('-> (.*?) using filter', process.stdout.decode())
return filename.group(1)
def libreoffice_exec():
# TODO: Provide support for more platforms
if sys.platform == 'darwin':
return '/Applications/LibreOffice.app/Contents/MacOS/soffice'
return 'libreoffice'
and you call your function:
result = convert_to('TEMP Directory', 'Your File', timeout=15)

I have worked on this problem for half a day, so I think I should share some of my experience on this matter. Steven's answer is right, but it will fail on my computer. There are two key points to fix it here:
(1). The first time when I created the 'Word.Application' object, I should make it (the word app) visible before open any documents. (Actually, even I myself cannot explain why this works. If I do not do this on my computer, the program will crash when I try to open a document in the invisible model, then the 'Word.Application' object will be deleted by OS. )
(2). After doing (1), the program will work well sometimes but may fail often. The crash error "COMError: (-2147418111, 'Call was rejected by callee.', (None, None, None, 0, None))" means that the COM Server may not be able to response so quickly. So I add a delay before I tried to open a document.
After doing these two steps, the program will work perfectly with no failure anymore. The demo code is as below. If you have encountered the same problems, try to follow these two steps. Hope it helps.
import os
import comtypes.client
import time
wdFormatPDF = 17
# absolute path is needed
# be careful about the slash '\', use '\\' or '/' or raw string r"..."
in_file=r'absolute path of input docx file 1'
out_file=r'absolute path of output pdf file 1'
in_file2=r'absolute path of input docx file 2'
out_file2=r'absolute path of outputpdf file 2'
# print out filenames
print in_file
print out_file
print in_file2
print out_file2
# create COM object
word = comtypes.client.CreateObject('Word.Application')
# key point 1: make word visible before open a new document
word.Visible = True
# key point 2: wait for the COM Server to prepare well.
time.sleep(3)
# convert docx file 1 to pdf file 1
doc=word.Documents.Open(in_file) # open docx file 1
doc.SaveAs(out_file, FileFormat=wdFormatPDF) # conversion
doc.Close() # close docx file 1
word.Visible = False
# convert docx file 2 to pdf file 2
doc = word.Documents.Open(in_file2) # open docx file 2
doc.SaveAs(out_file2, FileFormat=wdFormatPDF) # conversion
doc.Close() # close docx file 2
word.Quit() # close Word Application

Works very nicely for doc, docx, ppt, pptx, xls, xlsx.
Very useful if you need to convert docs or save/convert to certain formats on a server.
As an alternative to the SaveAs function, you could also use ExportAsFixedFormat which gives you access to the PDF options dialog you would normally see in Word. With this you can specify bookmarks and other document properties.
doc.ExportAsFixedFormat(OutputFileName=pdf_file,
ExportFormat=17, #17 = PDF output, 18=XPS output
OpenAfterExport=False,
OptimizeFor=0, #0=Print (higher res), 1=Screen (lower res)
CreateBookmarks=1, #0=No bookmarks, 1=Heading bookmarks only, 2=bookmarks match word bookmarks
DocStructureTags=True
);
The full list of function arguments is: 'OutputFileName', 'ExportFormat', 'OpenAfterExport', 'OptimizeFor', 'Range', 'From', 'To', 'Item', 'IncludeDocProps', 'KeepIRM', 'CreateBookmarks', 'DocStructureTags', 'BitmapMissingFonts', 'UseISO19005_1', 'FixedFormatExtClassPtr'
It's worth noting that Stevens answer works, but make sure if using a for loop to export multiple files to place the ClientObject or Dispatch statements before the loop - it only needs to be created once - see my problem: Python win32com.client.Dispatch looping through Word documents and export to PDF; fails when next loop occurs
If you don't mind using PowerShell have a look at this Hey, Scripting Guy! article. The code presented could be adopted to use the wdFormatPDF enumeration value of WdSaveFormat (see here).
This blog article presents a different implementation of the same idea.
I have modified it for ppt support as well. My solution support all the below-specified extensions.
word_extensions = [".doc", ".odt", ".rtf", ".docx", ".dotm", ".docm"]
ppt_extensions = [".ppt", ".pptx"]

I have modified code from Docx2PDF
I tried the accepted answer but wasn't particularly keen on the bloated PDFs Word was producing which was usually an order of magnitude bigger than expected. After looking how to disable the dialogs when using a virtual PDF printer I came across Bullzip PDF Printer and I've been rather impressed with its features. It's now replaced the other virtual printers I used previously. You'll find a "free community edition" on their download page.
The COM API can be found here and a list of the usable settings can be found here. The settings are written to a "runonce" file which is used for one print job only and then removed automatically. When printing multiple PDFs we need to make sure one print job completes before starting another to ensure the settings are used correctly for each file.
import os, re, time, datetime, win32com.client
def print_to_Bullzip(file):
util = win32com.client.Dispatch("Bullzip.PDFUtil")
settings = win32com.client.Dispatch("Bullzip.PDFSettings")
settings.PrinterName = util.DefaultPrinterName # make sure we're controlling the right PDF printer
outputFile = re.sub("\.[^.]+$", ".pdf", file)
statusFile = re.sub("\.[^.]+$", ".status", file)
settings.SetValue("Output", outputFile)
settings.SetValue("ConfirmOverwrite", "no")
settings.SetValue("ShowSaveAS", "never")
settings.SetValue("ShowSettings", "never")
settings.SetValue("ShowPDF", "no")
settings.SetValue("ShowProgress", "no")
settings.SetValue("ShowProgressFinished", "no") # disable balloon tip
settings.SetValue("StatusFile", statusFile) # created after print job
settings.WriteSettings(True) # write settings to the runonce.ini
util.PrintFile(file, util.DefaultPrinterName) # send to Bullzip virtual printer
# wait until print job completes before continuing
# otherwise settings for the next job may not be used
timestamp = datetime.datetime.now()
while( (datetime.datetime.now() - timestamp).seconds < 10):
if os.path.exists(statusFile) and os.path.isfile(statusFile):
error = util.ReadIniString(statusFile, "Status", "Errors", '')
if error != "0":
raise IOError("PDF was created with errors")
os.remove(statusFile)
return
time.sleep(0.1)
raise IOError("PDF creation timed out")
I was working with this solution but I needed to search all .docx, .dotm, .docm, .odt, .doc or .rtf and then turn them all to .pdf (python 3.7.5). Hope it works...
import os
import win32com.client
wdFormatPDF = 17
for root, dirs, files in os.walk(r'your directory here'):
for f in files:
if f.endswith(".doc") or f.endswith(".odt") or f.endswith(".rtf"):
try:
print(f)
in_file=os.path.join(root,f)
word = win32com.client.Dispatch('Word.Application')
word.Visible = False
doc = word.Documents.Open(in_file)
doc.SaveAs(os.path.join(root,f[:-4]), FileFormat=wdFormatPDF)
doc.Close()
word.Quit()
word.Visible = True
print ('done')
os.remove(os.path.join(root,f))
pass
except:
print('could not open')
# os.remove(os.path.join(root,f))
elif f.endswith(".docx") or f.endswith(".dotm") or f.endswith(".docm"):
try:
print(f)
in_file=os.path.join(root,f)
word = win32com.client.Dispatch('Word.Application')
word.Visible = False
doc = word.Documents.Open(in_file)
doc.SaveAs(os.path.join(root,f[:-5]), FileFormat=wdFormatPDF)
doc.Close()
word.Quit()
word.Visible = True
print ('done')
os.remove(os.path.join(root,f))
pass
except:
print('could not open')
# os.remove(os.path.join(root,f))
else:
pass
The try and except was for those documents I couldn't read and won't exit the code until the last document.
You should start from investigating so called virtual PDF print drivers.
As soon as you will find one you should be able to write batch file that prints your DOC files into PDF files. You probably can do this in Python too (setup printer driver output and issue document/print command in MSWord, later can be done using command line AFAIR).
import docx2txt
from win32com import client
import os
files_from_folder = r"c:\\doc"
directory = os.fsencode(files_from_folder)
amount = 1
word = client.DispatchEx("Word.Application")
word.Visible = True
for file in os.listdir(directory):
filename = os.fsdecode(file)
print(filename)
if filename.endswith('docx'):
text = docx2txt.process(os.path.join(files_from_folder, filename))
print(f'{filename} transfered ({amount})')
amount += 1
new_filename = filename.split('.')[0] + '.txt'
try:
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
except:
os.mkdir(files_from_folder + r'\txt_files')
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
elif filename.endswith('doc'):
doc = word.Documents.Open(os.path.join(files_from_folder, filename))
text = doc.Range().Text
doc.Close()
print(f'{filename} transfered ({amount})')
amount += 1
new_filename = filename.split('.')[0] + '.txt'
try:
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
except:
os.mkdir(files_from_folder + r'\txt_files')
with open(os.path.join(files_from_folder + r'\txt_files', new_filename), 'w', encoding='utf-8') as t:
t.write(text)
word.Quit()

I would suggest ignoring your supervisor and use OpenOffice which has a Python api. OpenOffice has built in support for Python and someone created a library specific for this purpose (PyODConverter).
If he isn't happy with the output, tell him it could take you weeks to do it with word.
I'm trying to put all the anchor text on a page in a txt file
print(anchor.get('href'))
with open('file.txt', 'a') as fd:
fd.write(anchor.get('href') + '\n')
and the script executes with no errors but I cannot find file.txt anywhere on my computer. Am I missing out on something really obvious?
With file open mode a (append) the file will be created if it doesn't already exist, otherwise writes will be appended to the end of the file. As written in the question, the file will be created in the current directory of the running process... look there.
from bs4 import BeautifulSoup
import requests
response = requests.get('http://httpbin.org/')
soup = BeautifulSoup(response.text)
with open('file.txt', 'a') as fd:
links = (link.get('href') for link in soup.find_all('a'))
fd.write('\n'.join(links) + '\n')
Try to set a full path to filename, so you can find in this path.
Example:
print(anchor.get('href'))
with open('/home/wbk/file.txt', 'a') as fd:
fd.write(anchor.get('href') + '\n')
And yes, you can use 'a' to create a new file, although this is not a good practice. The 'a' is to append data to the end of an existing file as describes doc
The following code works for me:
with open("example.txt","a") as a:
a.write("hello")
are you sure that the file isn't in your computer? In which ways you have demonstrated it? In my case, i work with eclipse IDE, so I have to refresh the Eclipse file explorer to see it..
Try this:
with open("prova.txt","a") as a:
a.write("ciao")
try: open("prova.txt","r")
except: print "file doesn't exist"
I modified the code based on the comments from experts in this thread. Now the script reads and writes all the individual files. The script reiterates, highlight and write the output. The current issue is, after highlighting the last instance of the search item, the script removes all the remaining contents after the last search instance in the output of each file.
Here is the modified code:
import os
import sys
import re
source = raw_input("Enter the source files path:")
listfiles = os.listdir(source)
for f in listfiles:
filepath = source+'\\'+f
infile = open(filepath, 'r+')
source_content = infile.read()
color = ('red')
regex = re.compile(r"(\b be \b)|(\b by \b)|(\b user \b)|(\bmay\b)|(\bmight\b)|(\bwill\b)|(\b's\b)|(\bdon't\b)|(\bdoesn't\b)|(\bwon't\b)|(\bsupport\b)|(\bcan't\b)|(\bkill\b)|(\betc\b)|(\b NA \b)|(\bfollow\b)|(\bhang\b)|(\bbelow\b)", re.I)
i = 0; output = ""
for m in regex.finditer(source_content):
output += "".join([source_content[i:m.start()],
"<strong><span style='color:%s'>" % color[0:],
source_content[m.start():m.end()],
"</span></strong>"])
i = m.end()
outfile = open(filepath, 'w+')
outfile.seek(0)
outfile.write(output)
print "\nProcess Completed!\n"
infile.close()
outfile.close()
raw_input()
The error message tells you what the error is:
No such file or directory: 'sample1.html'
Make sure the file exists. Or do a try statement to give it a default behavior.
The reason why you get that error is because the python script doesn't have any knowledge about where the files are located that you want to open.
You have to provide the file path to open it as I have done below. I have simply concatenated the source file path+'\\'+filename and saved the result in a variable named as filepath. Now simply use this variable to open a file in open().
import os
import sys
source = raw_input("Enter the source files path:")
listfiles = os.listdir(source)
for f in listfiles:
filepath = source+'\\'+f # This is the file path
infile = open(filepath, 'r')
Also there are couple of other problems with your code, if you want to open the file for both reading and writing then you have to use r+ mode. More over in case of Windows if you open a file using r+ mode then you may have to use file.seek() before file.write() to avoid an other issue. You can read the reason for using the file.seek() here.
New to Python & BeautifulSoup. I have a Python program that opens a file called "example.html", runs a BeautifulSoup action on it, then runs a Bleach action on it, then saves the result as file "example-cleaned.html". So far it is working for all contents of "example.html".
I need to modify it so that it opens each file in folder "/posts/", runs the program on it, then saves it out as "/posts-cleaned/X-cleaned.html" where X is the original filename.
Here's my code, minimised:
from bs4 import BeautifulSoup
import bleach
import re
text = BeautifulSoup(open("posts/example.html"))
text.encode("utf-8")
tag_black_list = ['iframe', 'script']
tag_white_list = ['p','div']
attr_white_list = {'*': ['title']}
# Step one, with BeautifulSoup: Remove tags in tag_black_list, destroy contents.
[s.decompose() for s in text(tag_black_list)]
pretty = (text.prettify())
# Step two, with Bleach: Remove tags and attributes not in whitelists, leave tag contents.
cleaned = bleach.clean(pretty, strip="TRUE", attributes=attr_white_list, tags=tag_white_list)
fout = open("posts/example-cleaned.html", "w")
fout.write(cleaned.encode("utf-8"))
fout.close()
print "Done"
Assistance & pointers to existing solutions gladly received!
You can use os.listdir() to get a list of all files in a directory. If you want to recurse all the way down the directory tree, you'll need os.walk().
I would move all this code to handle a single file to function, and then write a second function to handle parsing the whole directory. Something like this:
def clean_dir(directory):
os.chdir(directory)
for filename in os.listdir(directory):
clean_file(filename)
def clean_file(filename):
tag_black_list = ['iframe', 'script']
tag_white_list = ['p','div']
attr_white_list = {'*': ['title']}
with open(filename, 'r') as fhandle:
text = BeautifulSoup(fhandle)
text.encode("utf-8")
# Step one, with BeautifulSoup: Remove tags in tag_black_list, destroy contents.
[s.decompose() for s in text(tag_black_list)]
pretty = (text.prettify())
# Step two, with Bleach: Remove tags and attributes not in whitelists, leave tag contents.
cleaned = bleach.clean(pretty, strip="TRUE", attributes=attr_white_list, tags=tag_white_list)
# this appends -cleaned to the file;
# relies on the file having a '.'
dot_pos = filename.rfind('.')
cleaned_filename = '{0}-cleaned{1}'.format(filename[:dot_pos], filename[dot_pos:])
with open(cleaned_filename, 'w') as fout:
fout.write(cleaned.encode("utf-8"))
print "Done"
Then you just call clean_dir('/posts') or what not.
I'm appending "-cleaned" to the files, but I think I like your idea of using a whole new directory better. That way you won't have to handle conflicts if -cleaned already exists for some file, etc.
I'm also using the with statement to open files here as it closes them and handles exceptions automatically.
Answer to my own question, for others who might find the Python docs for os.listdir a bit unhelpful:
from bs4 import BeautifulSoup
import bleach
import re
import os, os.path
tag_black_list = ['iframe', 'script']
tag_white_list = ['p','div']
attr_white_list = {'*': ['title']}
postlist = os.listdir("posts/")
for post in postlist:
# HERE: you need to specify the directory again, the value of "post" is just the filename:
text = BeautifulSoup(open("posts/"+post))
text.encode("utf-8")
# Step one, with BeautifulSoup: Remove tags in tag_black_list, destroy contents.
[s.decompose() for s in text(tag_black_list)]
pretty = (text.prettify())
# Step two, with Bleach: Remove tags and attributes not in whitelists, leave tag contents.
cleaned = bleach.clean(pretty, strip="TRUE", attributes=attr_white_list, tags=tag_white_list)
fout = open("posts-cleaned/"+post, "w")
fout.write(cleaned.encode("utf-8"))
fout.close()
I cheated and made a separate folder called "posts-cleaned/" because savings files to there was easier than splitting the filename, adding "cleaned", and re-joining it, although if anyone wants to show me a good way to do that, that would be even better.
