Use the Connect Server to Access Excel Data in Microsoft Power Pivot

This article will explain how to use the Connect Server to provide Excel data as OData services and then consume the data in Microsoft Excel's Power Pivot business intelligence tool. Follow the steps below to retrieve and edit Excel data in Power Pivot.

Connect to Excel from Power Pivot

To work with live Excel data in Power Pivot, we need to connect to Excel from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Excel data.

Add a Connect Server User

Create a User to connect to Excel from Power Pivot through Connect Server.

1. Click Users -> Add
2. Configure a User
3. Click Save Changes and make note of the Authtoken for the new user

Connect to Excel from Connect Server

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Open Connect Server and click Connections
2. Select "Excel" from Available Data Sources
3. Enter the necessary authentication properties to connect to Excel.

   The ExcelFile, under the Authentication section, must be set to a valid Excel File.

4. Click Save Changes
5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions (SELECT is all that is required for Reveal).

Add Excel OData Endpoints in Connect Server

After connecting to Excel, create OData Endpoints for the desired table(s).

1. Click OData -> Tables -> Add Tables
2. Select the Excel database
3. Select the table(s) you wish to work with and click Next
4. (Optional) Edit the resource to select specific fields and more
5. Save the settings

(Optional) Configure Cross-Origin Resource Sharing (CORS)

When accessing and connecting to multiple domains from an application, there is a possibility of violating the limitations of cross-site scripting. In that case, configure the CORS settings in OData -> Settings.

• Enable cross-origin resource sharing (CORS): ON
• Allow all domains without '*': ON
• Access-Control-Allow-Methods: GET, PUT, POST, OPTIONS
• Access-Control-Allow-Headers: Authorization

Save the changes to the settings.

Import Excel Tables in Power Pivot

Follow the steps below to import tables that can be refreshed on demand:

1. In Excel, click Data -> Get Data -> From Other Sources -> From OData Feed
2. Fill out the OData feed URL (e.g. http://localhost:8080/odata.rsc)
3. On the next screen, select Basic and configure the username and password. Password should be your auth token.

4. Select the tables that you would like to import into Excel

5. After selecting your table(s) and clicking Load, you should see the data appear in an Excel spreadsheet

6. Now, click the Power Pivot tab on the ribbon, and then select Add to Data Model. This can now work with your Excel data in Power Pivot.
