Connect to Google Data Catalog from Power Query
To work with live Google Data Catalog data in Microsoft Power Query, we need to connect to Google Data Catalog from Connect Server, provide user access to the new virtual database, and create OData endpoints for the Google Data Catalog data.
Add a Connect Server User
Create a User to connect to Google Data Catalog from Microsoft Power Query through Connect Server.
- Click Users -> Add
- Configure a User
- Click Save Changes and make note of the Authtoken for the new user
Connect to Google Data Catalog from Connect Server
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Open Connect Server and click Connections
- Select "Google Data Catalog" from Available Data Sources
- Enter the necessary authentication properties to connect to Google Data Catalog.
Google Data Catalog uses the OAuth authentication standard. Authorize access to Google APIs on behalf on individual users or on behalf of users in a domain.
Before connecting, specify the following to identify the organization and project you would like to connect to:
- OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.
Click the project selection drop-down, and select your organization from the list. Then, click More -> Settings. The organization ID is displayed on this page.
- ProjectId: The ID associated with the Google Cloud Platform project resource you would like to connect to.
Find this by navigating to the cloud console dashboard and selecting your project from the Select from drop-down. The project ID will be present in the Project info card.
When you connect, the OAuth endpoint opens in your default browser. Log in and grant permissions to the application to completes the OAuth process. For more information, refer to the OAuth section in the Help documentation.
- OrganizationId: The ID associated with the Google Cloud Platform organization resource you would like to connect to. Find this by navigating to the cloud console.
- Click Save Changes
- 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 Google Data Catalog OData Endpoints in Connect Server
After connecting to Google Data Catalog, create OData Endpoints for the desired table(s).
- Click OData -> Tables -> Add Tables
- Select the Google Data Catalog database
- Select the table(s) you wish to work with and click Next
- (Optional) Edit the resource to select specific fields and more
- Save the settings
(Optional) Configure Cross-Origin Resource Sharing (CORS)
When accessing and connecting to multiple domains from an application such as Ajax, 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.
Connect to Google Data Catalog Data from Power Query
Follow the steps below to import tables that can be refreshed on demand:
- Configure the Connect Server to use a version of the OData protocol that is recognized by Power Query. In the Connect Server administration console, click Settings -> Server and change the value of the Default Version property to 3.0.
-
From the ribbon in Excel, click Power Query -> From Other Data Sources -> From OData Feed, and enter the OData URL:
https://your-server:8032/api.rsc
-
Next, define authentication credentials and set privacy levels. Select Basic authentication and enter the credentials for a user authorized to make requests. Specify the Username field and enter the user's authtoken in the Password field.
To change the authentication scheme that Power Query will use, click Power Query -> Data Source Settings. Select the OData feed from the list and then click "Edit Permissions..." Select the privacy level from the menu.
-
You can now access Google Data Catalog data in Power Query. In the Navigator expand the node for the OData feed, right-click a table, and click Edit to open the Query Editor. This will display the table data.
