python - .xlsx 和 xls(最新版本)使用 python 到 pdf

Question

借助这个.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()

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

有问题

doc.SaveAs(out_file, FileFormat=56)

FileFormat 文件格式应该是什么？请帮忙

Answer 1

xlsxwriter 链接:

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

借助于此，您可以生成包含 .xlsx 和 .xls

的 excel 文件

例如excel文件生成的名字是trial.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')
