Connect to a SharePoint folder

To connect to a SharePoint folder:

  1. Select the SharePoint folder option in the connector selection.

  2. Find the address (also known as a URL) of your SharePoint site that contains the folder you want to use.

    From a page in SharePoint, you can usually get the site address by selecting Home in the navigation pane, or the icon for the site at the top, then copying the address from your web browser's address bar.

  3. If you're connecting from Power BI desktop or Excel:

    1. Paste the address into the Site URL test box in the SharePoint folder dialog box. In this case, the site URL is If the site URL you enter is invalid, a warning icon warning icon will appear next to the URL textbox.

    Combine files from SharePoint folder


The Combine & Transform Data and Combine & Load buttons are the easiest ways to combine data found in the files of the SharePoint folder you specify. You could also use the Load button (in Power BI Desktop only) or the Transform Data buttons to combine the files as well, but that requires more manual steps.


Combining files

All of the files in the SharePoint folder you select will be included in the data to be combined. If you have data files located in a subfolder of the SharePoint folder you select, all of these files will also be included. To ensure that combining the file data works properly, make sure that all of the files in the folder and the subfolders have the same schema.

In some cases, you might have multiple folders on your SharePoint site containing different types of data. In this case, you'll need to delete the unnecessary files. To delete these files:

  1. In the list of files from the SharePoint folder you chose, select Transform Data.

  2. In the Power Query editor, scroll down to find the files you want to keep.

  3. In the example shown in the screenshot above, the required files are the last rows in the table. Select Remove Rows, enter the value of the last row before the files to keep (in this case 903), and select OK.

  4. Once you've removed all the unnecessary files, select Combine Files from the Home ribbon to combine the data from all of the remaining files.

For more information about combining files, see Combine files in Power Query.

Filename special characters

If a filename contains certain special characters, it may lead to authentication errors due to the filename being truncated in the URL. If you are getting unusual authentication errors, make sure that all of the filenames you're using don't contain any of the following special characters.

# % $

If these characters are present in the filename, the file owner must rename the file so that it does NOT contain any of these characters.
