您好，我正在尝试使用 python 将 excel 工作表转换为 pdf，将编写的脚本转换为对 word 文档执行相同操作，它工作正常，但在下面标记此错误

Traceback (most recent call last):
  File "C:/Users/alank/Python training/Exceltopdf2.py", line 13, in <module>
    xlxs.SaveAs(out_file, FileFormat=xlxsFormatPDF)
OSError: exception: access violation reading 0xFFFFFFFFFFFFFFFF

任何帮助表示赞赏，脚本如下

import sys
import os
import comtypes.client

xlxsFormatPDF = 17

in_file = (r'C:\Users\alank\Python training\Helloworld.xlsx')
out_file = (r'C:\Users\alank\Python training\Helloworld.pdf')


excel = comtypes.client.CreateObject('Excel.Application')
xlxs = excel.workbooks.Open(in_file)
xlxs.SaveAs(out_file, FileFormat=xlxsFormatPDF)
xlxs.Close()
excel.Quit()

你可以试试win32com.client 像这样：

import win32com.client
from pywintypes import com_error


WB_PATH =   r'C:\Users\alank\Python training\Helloworld.xlsx'

PATH_TO_PDF = r'C:\Users\alank\Python training\Helloworld.pdf'


excel.Visible = False
try:
    # Open
    wb = excel.Workbooks.Open(WB_PATH)

    # Specify the sheet you want to save by index. 
    #if you want all the sheets in excel try with: 
    #wb.WorkSheets(wb.Sheets.Count) or wb.WorkSheets([i=1 for i in range(wb.Sheets.Count)]).Select() 
    ws_index_list = [1,2,3,4,5,6,7,8,9,10,11,12]
    wb.WorkSheets(ws_index_list).Select()

    # Save
    wb.ActiveSheet.ExportAsFixedFormat(0, PATH_TO_PDF)
except com_error as e:
    print('The convertion failed.')
else:
    print('Succeessful convertion')
finally:
    wb.Close()
    excel.Quit()

或者你可以像here (Andreas solution)：

import os
import comtypes.client

SOURCE_DIR = r'C:\Users\alank\Python training'
TARGET_DIR = r'C:\Users\alank\Python training'

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

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

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

app.Quit()
