CData Connect Server

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



Use the Connect Server to connect to live GitHub data in the Power Pivot business intelligence tool.

This article will explain how to use the Connect Server to provide GitHub 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 GitHub data in Power Pivot.

Connect to GitHub from Power Pivot

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

Add a Connect Server User

Create a User to connect to GitHub 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 GitHub 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 "GitHub" from Available Data Sources
  3. Enter the necessary authentication properties to connect to GitHub.

    GitHub uses the OAuth 2 authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Getting Started chapter of the CData help documentation for an authentication guide.

  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 GitHub OData Endpoints in Connect Server

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

  1. Click OData -> Tables -> Add Tables
  2. Select the GitHub 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 GitHub 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 GitHub data in Power Pivot.
