Error when converting Excel document to pdf using comtypes in Python

Question

I am trying to convert an Excel spreadsheet to PDF using Python and the comtypes package using this code:

import os
import comtypes.client

FORMAT_PDF = 17
S         


        

Answer 1

Found a solution - this seems to be working:

import os
import comtypes.client

SOURCE_DIR = 'C:/Users/IEUser/Documents/jscript/test/resources/root3'
TARGET_DIR = 'C:/Users/IEUser/Documents/jscript'

app = comtypes.client.CreateObject('Excel.Application')
app.Visible = False

infile = os.path.join(os.path.abspath(SOURCE_DIR), 'spreadsheet1.xlsx')
outfile = os.path.join(os.path.abspath(TARGET_DIR), 'spreadsheet1.pdf')

doc = app.Workbooks.Open(infile)
doc.ExportAsFixedFormat(0, outfile, 1, 0)
doc.Close()

app.Quit()

This link may also be helpful as an inspiration regarding the arguments to the ExportAsFixedFormatfunction: Document.ExportAsFixedFormat Method (although some of the values of arguments have to be modified a bit).
