“我正在尝试使用来自 How to read SharePoint Online (Office365) Excel files into Python specifically pandas with Work or School Account? 答案的代码，但得到 XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'\r\n

#import all the libraries
from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.files.file import File 
import io
import pandas as pd

#target url taken from sharepoint and credentials
url = 'https://company.sharepoint.com/Shared%20Documents/Folder%20Number1/Folder%20Number2/Folder3/Folder%20Number4/Target_Excel_File_v4.xlsx?cid=_Random_letters_and_numbers-21dbf74c'
username = 'Dumby_account@company.com'
password = 'Password!'

ctx_auth = AuthenticationContext(url)
if ctx_auth.acquire_token_for_user(username, password):
  ctx = ClientContext(url, ctx_auth)
  web = ctx.web
  ctx.load(web)
  ctx.execute_query()
  print("Authentication successful")

response = File.open_binary(ctx, url)

#save data to BytesIO stream
bytes_file_obj = io.BytesIO()
bytes_file_obj.write(response.content)
bytes_file_obj.seek(0) #set file object to start

#read excel file and each sheet into pandas dataframe 
df = pd.read_excel(bytes_file_obj, sheetname = None)

【解决方案1】：

我通过在桌面中打开文件并转到文件 > 信息 > 复制路径来做到这一点。这条路径应该可行。

【解决方案2】：

看起来您使用的是共享链接而不是文件路径。您需要复制正确的路径。方法如下：

打开共享点文件夹
点击文件中的三个点，然后点击详细信息
向下滚动并复制路径路径应类似于：'/user/folder/Documents/Target_Excel_File_v4.xlsx'

使用 sharepoint url 进行身份验证，然后使用复制的路径打开您的二进制文件。

from office365.sharepoint.files.file import File

#target url taken from sharepoint and credentials
url = 'https://company.sharepoint.com/user/folder'
path = '/user/folder/Documents/Target_Excel_File_v4.xlsx'
username = 'Dumby_account@company.com'
password = 'Password!'

ctx_auth = AuthenticationContext(url)
if ctx_auth.acquire_token_for_user(username, password):
  ctx = ClientContext(url, ctx_auth)
  web = ctx.web
  ctx.load(web)
  ctx.execute_query()
  print("Authentication successful")

response = File.open_binary(ctx, path)

#save data to BytesIO stream
bytes_file_obj = io.BytesIO()
bytes_file_obj.write(response.content)
bytes_file_obj.seek(0) #set file object to start

#read excel file and each sheet into pandas dataframe 
df = pd.read_excel(bytes_file_obj, sheetname = None)
