Import and Visualize Google Cloud Storage Data in Power View

You can use the built-in ODBC support in Excel to rapidly create Power View reports featuring Google Cloud Storage data. This article shows how to use the Data Connection Wizard, accessible from the Data ribbon, to import Google Cloud Storage data into a Power View report.

Connect to Google Cloud Storage as an ODBC Data Source

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Authenticate with a User Account

You can connect without setting any connection properties for your user credentials. After setting InitiateOAuth to GETANDREFRESH, you are ready to connect.

When you connect, the Google Cloud Storage OAuth endpoint opens in your default browser. Log in and grant permissions, then the OAuth process completes

Authenticate with a Service Account

Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes.

You need to create an OAuth application in this flow. See the Help documentation for more information. After setting the following connection properties, you are ready to connect:

• InitiateOAuth: Set this to GETANDREFRESH.
• OAuthJWTCertType: Set this to "PFXFILE".
• OAuthJWTCert: Set this to the path to the .p12 file you generated.
• OAuthJWTCertPassword: Set this to the password of the .p12 file.
• OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
• OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
• OAuthJWTSubject: Set this to your enterprise Id if your subject type is set to "enterprise" or your app user Id if your subject type is set to "user".
• ProjectId: Set this to the Id of the project you want to connect to.

The OAuth flow for a service account then completes.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Connect with the Data Connection Wizard

Follow the steps below to connect to the DSN from the Data Connection Wizard in Excel.

1. On the Data tab, click From Other Sources -> From Data Connection Wizard.
2. In the Data Connection Wizard, select the ODBC DSN option.
3. Select the ODBC DSN for Google Cloud Storage from the list.

4. Select the tables you want to work with.

   If you want to import multiple tables, deselect the "Connect to a specific table" option. After you connect to the data source, you can select multiple tables: After you click Finish to close the Data Connection Wizard, select the "Enable selection of multiple tables" option in the Select Table dialog.

5. In the Import Data dialog, select the destination for your data. For example, select the Table option and the Existing worksheet option. Then click the cell in your worksheet where results should be output.
6. Click Insert -> Power View to create a new Power View report.

Create a Table

Tables are the starting point for charts and other representations of your data. To create a table, select a column in the field list. You can also drag and drop table names and column names onto the view.

Create Data Visualizations

On the Design tab, you can change tables into charts and other visualizations.
