How to transfer Office files to PDF by Python

This article introduces the knowledge about "Python how to convert Office files to PDF". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

Install Win32com

Before actual combat, you need to install Python win32com, the detailed installation steps are as follows:

Install pip install pywin32 with pip command

If we encounter an installation error, we can install it by updating the cloud with python -m pip install --upgrade pip:

python -m pip install --upgrade pip download offline install package install

If the pip command is not installed successfully, you can also download the offline package installation, the method steps are as follows: First, select the corresponding Python version on the official website to download the offline package: sourceforge.net/projects/pywin32/files/pywin32/Build%20221/ Download and install it foolishly.

file conversion logic

The detailed codes are as follows:

class PDFConverter: def __init__(self, pathname, export='. '): self._ handle_postfix = ['doc',' docx','ppt', 'pptx', 'xls', 'xlsx']#File types supported for conversion self._ filename_list = list() #List files self._ export_folder = os.path.join(os.path.abspath('. '), 'file_server/pdfconver') if not os.path.exists(self._ export_folder): os.mkdir(self._ export_folder) self._ enumerate_filename(pathname) def _enumerate_filename(self, pathname): ''' Read all file names ''' full_pathname = os.path.abspath(pathname) if os.path.isfile(full_pathname): if self._ is_legal_postfix(full_pathname): self._ filename_list.append(full_pathname) else: raise TypeError ('file {} suffix name illegal! Only the following file types are supported: {}. '.format(pathname, '、'.join(self._ handle_postfix))) elif os.path.isdir(full_pathname): for relpath, _, files in os.walk(full_pathname): for name in files: filename = os.path.join(full_pathname, relpath, name) if self._ is_legal_postfix(filename): self._ filename_list.append(os.path.join(filename)) else: The file/folder {} does not exist or is invalid. '.format(pathname)) def _is_legal_postfix(self, filename): return filename.split('. ')[-1].lower() in self._ handle_postfix and not os.path.basename(filename).startswith( '~') def run_conver(self): print ('Number of files to convert is: ', len(self._ filename_list)) for filename in self._ filename_list: postfix = filename.split('. ')[-1].lower() funcCall = getattr(self, postfix) print ('original file', filename) funcCall(filename) print ('Conversion complete! ')doc/docx to PDF

The doc/docx conversion to PDF code is as follows:

def doc(self, filename): name = os.path.basename(filename).split('. ')[0] + '.pdf' exportfile = os.path.join(self._ export_folder, name) print ('Save PDF file:', exportfile) gencache.EnsureModule('{00020905-0000-0000-C000-000000000046}', 0, 8, 4) pythoncom.CoInitialize() w = Dispatch("Word.Application") pythoncom.CoInitialize() #plus prevent CoInitialize from not loading doc = w.Documents.Open(filename) doc.ExportAsFixedFormat(exportfile, constants.wdExportFormatPDF, Item=constants.wdExportDocumentWithMarkup, CreateBookmarks=constants.wdExportCreateHeadingBookmarks) w.Quit(constants.wdDoNotSaveChanges) def docx(self, filename): self.doc (filename)ppt/pptx to PDF

The ppt/pptx conversion to PDF code is as follows:

def ppt(self, filename): name = os.path.basename(filename).split('. ')[0] + '.pdf' exportfile = os.path.join(self._ export_folder, name) gencache.EnsureModule('{00020905-0000-0000-C000-000000000046}', 0, 8, 4) pythoncom.CoInitialize() p = Dispatch("PowerPoint.Application") pythoncom.CoInitialize() ppt = p.Presentations.Open(filename, False, False, False) ppt.ExportAsFixedFormat(exportfile, 2, PrintRange=None) print ('Save PDF file:', exportfile) p.Quit() def pptx(self, filename): self.ppt(filename)xls/xlsx to PDF def xls(self, filename): name = os.path.basename(filename).split('. ')[0] + '.pdf' exportfile = os.path.join(self._ export_folder, name) pythoncom.CoInitialize() xlApp = DispatchEx("Excel.Application") pythoncom.CoInitialize() xlApp.Visible = False xlApp.DisplayAlerts = 0 books = xlApp.Workbooks.Open(filename, False) books.ExportAsFixedFormat(0, exportfile) books.Close(False) print ('Save PDF file:', exportfile) xlApp.Quit() def xlsx(self, filename): self.xls(filename) performs conversion logic if __name__= "__main__": #Support folder batch import #folder = 'tmp' #pathname = os.path.join(os.path.abspath('. '), folder) #also supports conversion of individual files pathname = "G:/python_study/test.doc" pdfConverter = PDFConverter(pathname) pdfConverter.run_conver()"Python how to convert Office files to PDF" content is introduced here, thank you for reading.
