When working with Excel Power Query to connect to SharePoint workbooks, users may encounter the frustrating error message: "We couldn't authenticate with the credentials provided." This error can halt your workflow and make data analysis feel like an uphill battle. In this article, we’ll explore the potential causes of this issue, provide a solution, and offer tips to ensure smooth operation between Excel and SharePoint.
Understanding the Problem
The problem arises when Excel Power Query attempts to access a SharePoint workbook using credentials that are either incorrect, not configured properly, or lack the necessary permissions. The message indicates that Power Query cannot authenticate your identity to gain access to the resource, which can hinder your ability to retrieve or manipulate data effectively.
Original Code/Connection Setup (Example)
let
Source = SharePoint.Files("https://yourdomain.sharepoint.com/sites/yoursite", [ApiVersion = 15]),
YourFile = Source{[Name="YourWorkbook.xlsx"]}[Content],
Data = Excel.Workbook(YourFile)
in

Analyzing the Error
-
Check Your Credentials: Ensure that the username and password you are using to authenticate to SharePoint are correct. Sometimes, using your Microsoft account instead of the organizational account can cause issues.
-
Sign in to SharePoint: Open your SharePoint site in a web browser to ensure that you can access it with the same credentials you are using in Excel.
-
Check for Multi-Factor Authentication: If your organization has implemented Multi-Factor Authentication (MFA), you may need to provide additional verification steps that Power Query does not support directly.
-
Permission Levels: Ensure that your account has the appropriate permissions to access the SharePoint site and the specific workbook you are trying to connect to. You may need to reach out to your IT department for assistance.
-
Update Power Query: Make sure you are using the latest version of Excel, as updates often include important bug fixes and improvements for connectivity features.
Solutions to the Authentication Issue
Step 1: Use the Correct Connection Method
When setting up your connection in Power Query, ensure you are selecting the proper authentication method. For Office 365 or SharePoint Online, choose “Organizational account” from the authentication options.
Step 2: Refresh Connections
Sometimes, simply refreshing the connection in Power Query can resolve authentication issues. To do this:
- Open Power Query Editor.
- Go to "Home" > "Refresh Preview" or "Close & Load" to refresh the data.
Step 3: Clear Cached Credentials
If there are old cached credentials causing conflicts, clearing them can help:
- Go to "File" > "Options" > "Data" > "Edit Data Source Settings."
- Select your data source and click "Clear Permissions."
Example of a Working Connection
Here’s a simplified version of a working Power Query connection to a SharePoint workbook:
let
Source = SharePoint.Files("https://yourdomain.sharepoint.com/sites/yoursite", [ApiVersion = 15]),
YourFile = Source{[Name="YourWorkbook.xlsx"]}[Content],
Data = Excel.Workbook(YourFile)
in
Data
Ensure that you replace placeholders like https://yourdomain.sharepoint.com/sites/yoursite and YourWorkbook.xlsx with your actual site and workbook names.
Additional Tips for Smooth Operation
- Check for Updates Regularly: Always ensure that your Excel and Power Query add-ins are up to date.
- Documentation: Refer to Microsoft's official documentation for SharePoint and Excel Power Query for the most accurate instructions.
- Community Forums: Online communities, like Microsoft Tech Community and Stack Overflow, can be invaluable resources for troubleshooting similar issues.
Conclusion
The error message "We couldn't authenticate with the credentials provided" can be a roadblock when working with Excel Power Query and SharePoint. By following the troubleshooting steps outlined above and ensuring that your credentials and permissions are correctly set up, you can seamlessly access your SharePoint workbooks and continue your data analysis without interruption.
