Build Excel Online Visualizations in Tableau Cloud

Tableau Cloud is an analytics platform fully hosted in the cloud. When paired with CData Connect AI, you get instant, cloud-to-cloud access to Excel Online data for visualizations, dashboards, and more. This article shows how to connect to Excel Online and build visualizations from Excel Online data in Tableau Cloud.

CData Connect AI provides a pure cloud-to-cloud interface for Excel Online, allowing you to easily build visualizations from live Excel Online data in Tableau Cloud without installing connectors or publishing worksheets and data sources from Tableau Desktop. As you build visualizations, Tableau Cloud generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect AI pushes all supported SQL operations (filters, JOINs, etc) directly to Excel Online, leveraging server-side processing to quickly return Excel Online data.

Configure Excel Online Connectivity for Tableau Cloud

To work with Excel Online data from Tableau Cloud, we need to connect to Excel Online from Connect AI, provide user access to the connection, and create a Workspace for the Excel Online data.

Connect to Excel Online from Connect AI

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

1. Log into Connect AI, click Sources, and then click Add Connection
👁 Adding a Connection

2. Select "Excel Online" from the Add Connection panel
👁 Selecting a data source

3. Enter the necessary authentication properties to connect to Excel Online.

   You can connect to a workbook by providing authentication to Excel Online and then setting the following properties:

   • : Set this to the name or Id of the workbook.

     If you want to view a list of information about the available workbooks, execute a query to the Workbooks view after you authenticate.

   • : Set this to true if you are connecting to a workbook in a sandbox account. Otherwise, leave this blank to connect to a production account.

   You use the OAuth authentication standard to authenticate to Excel Online. See the Getting Started section in the help documentation for a guide. Getting Started also guides you through executing SQL to worksheets and ranges.

4. Click Save & Test
5. Navigate to the Permissions tab in the Add Excel Online Connection page and update the User-based permissions. 👁 Updating permissions
   

Add a Personal Access Token

When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.

1. Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
2. On the Settings page, go to the Access Tokens section and click Create PAT.
3. Give the PAT a name and click Create. 👁 Creating a new PAT
   
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Configure Excel Online Endpoints for Tableau Cloud

After connecting to Excel Online, create a workspace for your desired table(s).

1. Navigate to the Workspaces page and click Add to create a new Workspace (or select an existing workspace). 👁 The Workspaces page.
   👁 Adding a new Workspace.
   
2. Click Add to add new assets to the Workspace.
3. Select the Excel Online connection (e.g. ExcelOnline1) and click Next. 👁 Selecting an Asset (Salesforce is shown).
   
4. Select the table(s) you wish to work with and click Confirm. 👁 Selecting Tables (Salesforce is shown).
   
5. Make note of the OData Service URL for your workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}

With the connection, PAT, and Workspace configured, you are ready to connect to Excel Online data from Tableau Cloud.

Visualize Live Excel Online Data in Tableau Cloud

The steps below outline creating a new data source in Tableau Cloud based on the virtual Excel Online database in Connect AI and building a simple visualization from the data.

1. Log into Tableau Cloud, select a account, and create a new workbook.
2. In the new workbook, choose the OData Connector from the data wizard and fill in the values for your Connect AI instance. 👁 Selecting OData connector in Tableau Cloud
   
   • Set Server to the OData URL for your Workspace, e.g. https://cloud.cdata.com/api/odata/{workspace_name}
   • Set Authentication to Username and Password
   • Set Username to your Connect AI username (e.g. [email protected])
   • Set Password to a PAT for the above user
   👁 Connect to Connect AI from Tableau Cloud
   
3. Select your newly created database and the table(s) you wish to visualize (defining relationships for JOINad tables as needed).
👁 Choosing a Database and Tables

4. Select Dimensions and Measures and configure your visualization.
