Installation

You can install this package directly from the PyPI using pip or uv.

In the terminal type:

uv add spconnect

or

pip install spconnect

Instructions: Using the spconnect Package

This guide provides step-by-step instructions for using the spconnect package to interact with SharePoint via the Microsoft Graph API. The steps below use generic SharePoint site names, drives, folders, and files so you can adapt them to your own Sharepoint Site.

1. Install Required Packages

Ensure you have installed the spconnect package.

2. Store Credentials in a .env File

Create a .env file in the root directory containing your Microsoft Entra ID credentials. The file should look like this:

TENANT_ID=<your-tenant-id>
CLIENT_ID=<your-client-id>
CLIENT_SECRET=<your-client-secret>

3. Authenticate with Azure AD

Load credentials from the .env file using the python-dotenv package:

from dotenv import load_dotenv
import os
from spconnect import SharePointClient

load_dotenv()

tenant_id = os.getenv("TENANT_ID")
client_id = os.getenv("CLIENT_ID")
client_secret = os.getenv("CLIENT_SECRET")

client = SharePointClient(
    tenant_id=tenant_id,
    client_id=client_id,
    client_secret=client_secret,
    scopes=["https://graph.microsoft.com/.default"]
)

Note: Make sure to install python-dotenv if you haven't already:

4 Get Site, Drive and File IDs

The Microsoft Graph API uses a specific format to define the location of a file in a Sharepoint site. This can be summarised as:

site_id/drive_id/file_id

Note: confusingly the file_id is a distinct identifier pointing to a file within a drive. a file can be within folders in the drive, and the file ID covers the folders and file name

4.1 Extract IDs from a SharePoint File URL

You can use the parse_url_to_ids() method to extract the site_id, drive_id, and file_id directly from a SharePoint file URL. This is useful if you have a link to a file and want to quickly get the identifiers needed for other API calls.

To get the file URL from SharePoint:

• Locate the file in SharePoint.
• Click on the More Actions button (...) next to the file name.
• Scroll down until you find Path.
• Click on Copy Path to copy the file URL to your clipboard.

# Example SharePoint file URL (replace with your actual file URL)
file_url = "https://yourtenant.sharepoint.com/sites/YourSite/YourDrive/Your%20File.csv"

# This will return a dictionary with keys: 'site_id', 'drive_id', 'file_id'
ids = client.parse_url_to_ids(file_url)
print(ids)
# Output: {'site_id': '...', 'drive_id': '...', 'file_id': '...'}

# You can then use these IDs in other methods:
client.download_file_to_disk(ids['site_id'], ids['drive_id'], ids['file_id'], local_path="./downloads")

4.2 Find the site_id

The Microsoft Graph API uses a url in a specific format (not the url found in the browser when you visit a Sharepoint site) to_graph_site_url() converts the url found in a browser to the graph api format. This allows you to visit a Sharepoint site in browser, copy the url, and then paste it into the method to produce the graph api url.

graph_site_url = client.to_graph_site_url("https://yourcompany.sharepoint.com/sites/YourSite")
site_id = client.get_site_id(graph_site_url)

4.3 Find the drive_id

To view the drives within a site, you can use:

client.get_drives(site_id)

This will return a dictionary of drive names and IDs.

If you know the name of a drive (e.g. you are looking at it in a browser), the drive id can also be found using the name of the drive.

client.resolve_drive_id(site_id, "Documents")

4.4 Find the file_id

There are two main ways to find the file_id for a file in SharePoint:

From folder contents: Use get_folder_content(site_id, drive_id, folder_path) to list all files and folders in a location. This returns a dictionary where the keys are file IDs and the values are file names.

contents = client.get_folder_content(site_id, drive_id, folder_path="Shared Documents/Reports")

From file name: Use resolve_file_id(site_id, drive_id, file_name, folder_path) to get the file ID directly if you know the file name and (optionally) the folder path.

file_id = client.resolve_file_id(site_id, drive_id, file_name="file.csv", folder_path="Shared Documents/Reports")

You can then use the file_id with download, upload, or other file operations.

5. Download a File

To download a file from SharePoint:

client.download_file_to_disk(site_id, drive_id, file_id, local_path="./downloads")

6. Load a file into memory (as a byte file)

Load a file into memory, this is useful if you want to perform operations on the data before saving e.g. data cleaning:

byte_file = client.download_file_bytes(site_id, drive_id, file_id)

# Suppose the byte_file is an Excel file and you want to load it into polars
df = pl.read_excel(BytesIO(byte_file))

7. Upload a File

To upload a file to SharePoint:

• local_file_path: Path to the file on your computer
• upload_folder_path: Target folder in SharePoint (optional: if not supplied, the file will be uploaded to the root of the drive)

client.upload_file(
    local_file_path="./data/report.xlsx",
    site_id=site_id,
    drive_id=drive_id,
    upload_folder_path="Shared Documents/Reports"
)

Notes

• Replace all example values with your actual SharePoint site, drive, folder, and file names.
• Ensure your Azure AD app has the necessary permissions for Microsoft Graph API.
• For large files (>3MB), the package automatically uses chunked upload.
