使用 python 将 .xlsx 和 xls（最新版本）转换为 pdf

借助这个使用 python 将 .doc 转换为 pdf https://stackoverflow.com/questions/6011115/doc-to-pdf-using-python链接我正在尝试使用 Excel（.xlsx 和 xls 格式）

以下是修改后的Excel代码：

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()

它显示以下错误：

>>> execfile('excel_to_pdf.py')
Creating output folder...
C:\Excel\XlsxWriter-0.5.1\PDF_excel created.
apms_trial.xlsx
~$apms_trial.xlsx

有问题在

doc.SaveAs(out_file, FileFormat=56)

应该是什么文件格式文件格式？ 请帮忙

xlsxwriter的链接：

借助此功能，您可以生成 excel 文件.xlsx and .xls

例如excel文件生成的名称是审判.xls

现在，如果您想生成该 Excel 文件的 pdf，请执行以下操作：

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')
