Why SharePoint and OneDrive sources in Power BI? - Purpose & Use Cases

The Big Idea

What if your reports could update themselves without you lifting a finger?

The Scenario

Imagine you have important files scattered across SharePoint folders and OneDrive accounts. You need to gather data from all these places manually, opening each file, copying data into spreadsheets, and trying to keep track of updates.

The Problem

This manual process is slow and tiring. You risk making mistakes copying data, missing updates, or mixing versions. It's hard to keep everything current and accurate when you have to do it by hand every time.

The Solution

Using SharePoint and OneDrive sources in Power BI lets you connect directly to your files and folders. Power BI automatically pulls the latest data, so you don't have to copy or update anything manually. It saves time and reduces errors.

Before vs After

✗ Before

Open file > Copy data > Paste in Excel > Repeat for each file

✓ After

Power BI > Get Data > SharePoint Folder or OneDrive > Load and refresh

What It Enables

You can build live dashboards that update automatically as your SharePoint and OneDrive files change, giving you fresh insights without extra work.

Real Life Example

A sales manager connects Power BI to monthly sales reports stored in SharePoint. Instead of collecting files from the team, the dashboard updates itself every day with the latest numbers.

Key Takeaways

Manual data collection from SharePoint and OneDrive is slow and error-prone.

Power BI connects directly to these sources for automatic data refresh.

This creates up-to-date reports and saves you time and effort.

Practice

1. Which option in Power BI allows you to connect directly to files stored in SharePoint Online?

easy

A. SQL Server connector

B. SharePoint Folder connector

C. Azure Blob Storage connector

D. Local File connector

Solution

1. Step 1: Identify the correct connector for SharePoint Online

   Power BI provides a specific connector called 'SharePoint Folder' to access files stored in SharePoint Online.

2. Step 2: Eliminate other connectors

   SQL Server and Azure Blob Storage connectors are for different data sources, and Local File connector is for files on your computer.

3. Final Answer:

   SharePoint Folder connector -> Option B

4. Quick Check:

   SharePoint Folder = SharePoint Folder connector [OK]

Hint: Use 'SharePoint Folder' to connect to SharePoint files quickly [OK]

Common Mistakes:

• Choosing SQL Server connector for SharePoint data
• Using Local File connector for cloud files
• Confusing Azure Blob Storage with SharePoint

2. Which of the following is the correct URL format to connect Power BI to a SharePoint document library using the Web connector?

easy

A. https://company.sharepoint.com/sites/sitename/_layouts/15/start.aspx

B. https://company.sharepoint.com/sites/sitename/documents

C. https://company.sharepoint.com/sites/sitename/_api/web/lists/getbytitle('libraryname')/items

D. https://company.sharepoint.com/sites/sitename/libraryname

Solution

1. Step 1: Understand the URL needed for Web connector

   The Web connector requires the direct URL to the SharePoint document library root folder, which looks like https://company.sharepoint.com/sites/sitename/libraryname.

2. Step 2: Analyze other URL options

   https://company.sharepoint.com/sites/sitename/_layouts/15/start.aspx is a SharePoint start page, not a document library URL. https://company.sharepoint.com/sites/sitename/_api/web/lists/getbytitle('libraryname')/items is an API endpoint, not a direct folder URL. https://company.sharepoint.com/sites/sitename/documents is incorrect because 'documents' is not the standard library name unless customized.

3. Final Answer:

   https://company.sharepoint.com/sites/sitename/libraryname -> Option D

4. Quick Check:

   Correct SharePoint library URL = https://company.sharepoint.com/sites/sitename/libraryname [OK]

Hint: Use the direct library URL without extra paths for Web connector [OK]

Common Mistakes:

• Using SharePoint homepage URL instead of library URL
• Using API URLs instead of folder URLs
• Adding extra SharePoint layout paths

3. Given this Power Query M code snippet connecting to SharePoint folder:

Source = SharePoint.Files("https://company.sharepoint.com/sites/sales", [ApiVersion = 15])
Filtered = Table.SelectRows(Source, each Text.EndsWith([Name], ".xlsx"))

What does the 'Filtered' step return?

medium

A. All files in the SharePoint site ending with .xlsx

B. Only folders in the SharePoint site

C. All files except those ending with .xlsx

D. Only files from local drive

Solution

1. Step 1: Understand SharePoint.Files function

   This function lists all files and folders in the specified SharePoint site URL.

2. Step 2: Analyze the filter condition

   The filter keeps only rows where the file name ends with '.xlsx', so it selects Excel files only.

3. Final Answer:

   All files in the SharePoint site ending with .xlsx -> Option A

4. Quick Check:

   Filter by '.xlsx' files = All files in the SharePoint site ending with .xlsx [OK]

Hint: Text.EndsWith filters file extensions easily [OK]

Common Mistakes:

• Thinking it filters folders instead of files
• Assuming it excludes .xlsx files
• Confusing SharePoint files with local files

4. You try to connect Power BI to a SharePoint folder but get an error: "Access denied". Which of the following is the most likely cause?

medium

A. You do not have permission to access the SharePoint site

B. You used the wrong SharePoint URL format

C. Power BI does not support SharePoint connections

D. Your local file path is incorrect

Solution

1. Step 1: Understand the error message

   An "Access denied" error usually means the user lacks permission to access the SharePoint site or folder.

2. Step 2: Check other options

   Wrong URL format usually causes "Not found" errors, not access denied. Power BI supports SharePoint connections. Local file path is irrelevant for SharePoint connection.

3. Final Answer:

   You do not have permission to access the SharePoint site -> Option A

4. Quick Check:

   Access denied = Permission issue = You do not have permission to access the SharePoint site [OK]

Hint: Access denied usually means permission problem [OK]

Common Mistakes:

• Assuming URL format causes access denied
• Thinking Power BI can't connect to SharePoint
• Confusing local file errors with SharePoint errors

5. You want to create a Power BI report that automatically updates when new Excel files are added to a OneDrive folder. Which approach is best?

hard

A. Connect using SharePoint Folder connector with a static file path

B. Download files manually and import them into Power BI Desktop

C. Connect using OneDrive Folder connector and enable scheduled refresh

D. Use SQL Server connector to link OneDrive files

Solution

1. Step 1: Identify the correct connector for OneDrive files

   Power BI has a OneDrive Folder connector that connects directly to OneDrive folders and supports automatic refresh.

2. Step 2: Understand refresh options

   Enabling scheduled refresh allows the report to update when new files are added. Manual download is inefficient. SQL Server connector is unrelated. SharePoint Folder connector is for SharePoint, not OneDrive.

3. Final Answer:

   Connect using OneDrive Folder connector and enable scheduled refresh -> Option C

4. Quick Check:

   OneDrive Folder + scheduled refresh = Connect using OneDrive Folder connector and enable scheduled refresh [OK]

Hint: Use OneDrive Folder connector with refresh for auto updates [OK]

Common Mistakes:

• Manually importing files instead of connecting live
• Using SharePoint connector for OneDrive data
• Trying to use SQL Server connector for cloud files
