使用 python pandas 读取 sharepoint excel 文件

Question

"I'm trying to use this code from How to read SharePoint Online (Office365) Excel files into Python specifically pandas with Work or School Account? answers but a get the XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'\r\n<!DOCT'. I think the problem is in the way im placing my path. Do anybody knows how to get this type of Sharepoint path, like in the example below?" The ones I get look more like this "https://company.sharepoint.com/sites/site/Shared%20Documents/Forms/AllItems.aspx"

#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)

Answer 1

I did it by opening the file in desktop and going to file > info > Copy Path. This path should work.

Answer 2

Looks like you are using the share link instead of file path. You need to copy the correct path. Here's how:

1. Open the sharepoint folder
2. Click on the 3 dots in the file and click on Details
3. Scroll down and copy the Path the path should look something like: '/user/folder/Documents/Target_Excel_File_v4.xlsx'

Use the sharepoint url to authenticate and then use the copied path to open your binary file.

#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/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, sheet_name = None)
print(df)
