After you've created an app workspace in Power BI, you can store your Excel, CSV, and Power BI Desktop files on the OneDrive for Business for your Power BI app workspace. You can continue updating the files you store in OneDrive, and those updates are automatically reflected in the Power BI reports and dashboards based on the files.
Adding files to your app workspace is a two-step process:
First you upload files to the OneDrive for Business for your app workspace.
Then you connect to those files from Power BI.
App workspaces are only available with Power BI Pro.
In the Power BI service, select the arrow next to Workspaces > select the ellipsis (…) next to your workspace name.
Select Files to open the OneDrive for Business for your app workspace on Office 365.
Here, you can upload your files to the OneDrive for Business for your app workspace. Select Upload, and navigate to your files.
Now that your files are in the OneDrive for Business for your app workspace, you have a choice. You can:
Import the data from the Excel workbook as a dataset, and use the data to build reports and dashboards you can view in a web browser and on mobile devices.
Or connect to a whole Excel workbook in Power BI and display it exactly as it appears in Excel Online.
In Power BI, switch to the app workspace, so the app workspace name is in the top-left corner.
Select Get Data at the bottom of the left navigation pane.
In the Files box, select Get.
Select OneDrive - Your App Workspace Name.
Select the file you want > Connect.
Select Import or Connect.
If you select Import, then the workbook appears on the Datasets tab.
If you select Connect, then the workbook is on the Workbooks tab.
