.xlsx and xls(Latest Versions) to pdf using python

问题:

With the help of this .doc to pdf using python Link I am trying for excel (.xlsx and xls formats)

Following is modified Code for Excel:

import os from win32com import client  folder = "C:\\Oprance\\Excel\\XlsxWriter-0.5.1" file_type = 'xlsx' out_folder = folder + "\\PDF_excel"  os.chdir(folder)  if not os.path.exists(out_folder):     print 'Creating output folder...'     os.makedirs(out_folder)     print out_folder, 'created.' else:     print out_folder, 'already exists.\n'  for files in os.listdir("."):     if files.endswith(".xlsx"):         print files  print '\n\n'  word = client.DispatchEx("Excel.Application") for files in os.listdir("."):     if files.endswith(".xlsx") or files.endswith('xls'):         out_name = files.replace(file_type, r"pdf")         in_file = os.path.abspath(folder + "\\" + files)         out_file = os.path.abspath(out_folder + "\\" + out_name)         doc = word.Workbooks.Open(in_file)         print 'Exporting', out_file         doc.SaveAs(out_file, FileFormat=56)         doc.Close() 

It is showing following error :

>>> execfile('excel_to_pdf.py') Creating output folder... C:\Excel\XlsxWriter-0.5.1\PDF_excel created. apms_trial.xlsx ~$apms_trial.xlsx  Exporting C:\Excel\XlsxWriter-0.5.1\PDF_excel\apms_trial.pdf Traceback (most recent call last):   File "<stdin>", line 1, in <module>   File "excel_to_pdf.py", line 30, in <module>     doc = word.Workbooks.Open(in_file)   File "<COMObject <unknown>>", line 8, in Open pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, u'Microsoft Excel ', u"Excel cannot open the file '~$apms_trial.xlsx' because the file format or f ile extension is not valid. Verify that the file has not been corrupted and that  the file extension matches the format of the file.", u'xlmain11.chm', 0, -21468 27284), None) >>> 

There is problem in

doc.SaveAs(out_file, FileFormat=56)

What should be FileFormat file format? Please Help

Link of xlsxwriter :

With the help of this you can generate excel file with .xlsx and .xls

for example excel file generated name is trial.xls

Now if you want to generate pdf of that excel file then do the following :

from win32com import client xlApp = client.Dispatch("Excel.Application") books = xlApp.Workbooks.Open('C:\\excel\\trial.xls') ws = books.Worksheets[0] ws.Visible = 1 ws.ExportAsFixedFormat(0, 'C:\\excel\\trial.pdf')

You can print an excel sheet to pdf on linux using python. Do need to run openoffice as a headless server and use unoconv, takes a bit of configuring but is doable

You run OO as a (service) daemon and use it for the conversions for xls, xlsx and doc, docx.

I got the same thing and the same error... ANSWER: 57.... see below...

from win32com import client import win32api  def exceltopdf(doc):     excel = client.DispatchEx("Excel.Application")     excel.Visible = 0      wb = excel.Workbooks.Open(doc)     ws = wb.Worksheets[1]      try:         wb.SaveAs('c:\\targetfolder\\result.pdf', FileFormat=57)     except Exception, e:         print "Failed to convert"         print str(e)     finally:         wb.Close()         excel.Quit() 

... as an alternative to the fragile ExportAsFixedFormat...
