Question

在此.doc to pdf using python的帮助下链接我正在尝试excel（.xlsx和xls格式）

以下修改了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
~$apms_trial.xlsx

>>>

中存在问题

doc.SaveAs（out_file，FileFormat = 56）

FileFormat 文件格式应该是什么？请帮忙

Answer 1

xlsxwriter的链接：

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

借助此功能，您可以使用 .xlsx 和 .xls

生成Excel文件

例如，excel文件生成的名称为 trial.xls

现在，如果您要生成该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')

Answer 2

我得到同样的事情和同样的错误......答案：57 ....见下文......

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()

...作为脆弱的ExportAsFixedFormat的替代......

GroupDocs.Conversion Cloud SDK for Python 是另一种将 Excel 转换为 PDF 的选项。它是付费API。但是，它每月提供 150 次免费 API 调用。

P.S：我是 GroupDocs 的开发人员布道师。

# Import module
import groupdocs_conversion_cloud
from shutil import copyfile

# Get your client_id and client_key at https://dashboard.groupdocs.cloud (free registration is required).
client_id = "xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx"
client_key = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

# Create instance of the API
convert_api = groupdocs_conversion_cloud.ConvertApi.from_keys(client_id, client_key)

try:

        #Convert PDF to PNG
        # Prepare request
        request = groupdocs_conversion_cloud.ConvertDocumentDirectRequest("pdf", "C:/Temp/Book1.xlsx")

        # Convert
        result = convert_api.convert_document_direct(request)       
        copyfile(result, 'C:/Temp/Book1_output.pdf')
        print("Result {}".format(result))
        
except groupdocs_conversion_cloud.ApiException as e:
        print("Exception when calling get_supported_conversion_types: {0}".format(e.message))

Answer 4

您可以使用python在Excel上打印Excel表格。是否需要将openoffice作为无头服务器运行并使用unoconv，需要一些配置但是可行

您将OO作为（服务）守护程序运行，并将其用于xls，xlsx和doc，docx的转换。

.xlsx和xls（最新版本）到pdf使用python
