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

Question

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

There is problem in

doc.SaveAs(out_file, FileFormat=56)

What should be FileFormat file format? Please Help

Solution 1

Link of xlsxwriter :

https://xlsxwriter.readthedocs.org/en/latest/contents.html

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')

Solution 2

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...
