Question

我有这个以前曾用于其他电子邮件的脚本来下载附件：

import win32com.client as win
import xlrd

outlook = win.Dispatch("Outlook.Application").GetNamespace("MAPI")
inbox = outlook.GetDefaultFolder("6")
all_inbox = inbox.Items

subject = 'Email w/Attachment'

attachment1 = 'Attachment - 20160715.xls'

for msg in all_inbox:
    if msg.subject == subject:
        break
for att in msg.Attachments:    
    if att.FileName == attachment1:
        break
att.SaveAsFile('L:\\My Documents\\Desktop\\' + attachment1)

workbook = xlrd.open_workbook('L:\\My Documents\\Desktop\\' + attachment1)

然而，当我尝试使用xlrd阅读器（或使用pandas）打开文件时，我得到了这个：

raise XLRDError('Unsupported format, or corrupt file: ' + msg)

XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'\r\nVisit '

有谁能解释这里出了什么问题？

有没有办法可以打开附件而不保存，只需复制工作表并将该副本另存为.csv文件？

谢谢

看看这个question。您尝试下载的文件可能不是真正的Excel文件，而是保存为.xls文件的csv。证据是错误消息Expected BOF record; found b'\r\nVisit '。我认为excel文件将以<?xml或类似的东西开头。你可以用try / catch来解决它：

import pandas as pd
try: #try to read it as a .xls file
    workbook = xlrd.open_workbook(path)

except XLRDError: #if fails, read as csv
    workbook = pd.read_csv(path)

从outlook加载附件，使用pandas / xlrd加载时出错
