Publish Quandl-Connected Dashboards in Tableau Server

Use the CData Tableau Connector for Quandl and Tableau Server to visualize live Quandl data.

Tableau Server is a visual analytics platform transforming the way businesses use data to solve problems. When paired with the CData Tableau Connector for Quandl, you get access to live Quandl data within Tableau Server. This article shows how to connect to Quandl in Tableau Desktop, publish a Data Source to Tableau Server, and build a simple chart on that data.

The CData Tableau Connectors enable high-speed access to live Quandl data in Tableau Server. Once you install the connector, you simply authenticate with Quandl and you can immediately start building responsive, dynamic visualizations and dashboards. By surfacing Quandl data using native Tableau data types and handling complex filters, aggregations, & other operations automatically, CData Tableau Connectors grant seamless access to Quandl data.

NOTE: The CData Tableau Connectors require Tableau 2020.3 or higher. If you are using an older version of Tableau, you will need to use the CData JDBC Driver for Quandl. If you wish to connect to Quandl data in Tableau Online, you will need to use CData CloudHub.

Enable Connectivity to Quandl in Tableau Server

Start by installing the CData Tableau Connector on the machine hosting Tableau Server and on a machine with Tableau Desktop.

  1. On the server machine, copy cdata.quandl.taco and cdata.tableau.quandl.lic (typically found in C:\Program Files\CData\CData Tableau Connector for Quandl\lib\
  2. Place the copies in the Tableau Server Connectors folder (C:\ProgramData\Tableau\Tableau Server\data absvc\vizqlserver\Connectors)
  3. Restart Tableau Server

Connect to Quandl in Tableau Desktop

Once the connectors are installed on the Server machine, we can configure a connection to Quandl in Tableau Desktop and publish a Quandl-based Data Source to Tableau Server.

  1. Open Tableau Desktop
  2. Click More under Connect -> To a Server
  3. Select "Quandl by CData"
  4. Configure the connection and click "Sign In."

Quandl uses an API key for authentication. See the help documentation for a guide to obtaining the APIKey property.

Additionally, set the DatabaseCode connection property to the code identifying the Database whose Datasets you want to query with SQL. You can search the available Databases by querying the Databases view.

Discover Schemas and Query Data

Once you establish the connection to Quandl data, you can configure which entities to visualize.

  1. Select CData from the Database pull-down menu.
  2. Select Quandl from the Schema pull-down menu.
  3. Drag the tables and views you wish to visualize onto the join area. You can include multiple tables.
  4. Select Update Now or Automatically Update. Update Now lets you preview the first 10,000 rows of the data source (or enter the number of rows you want to see in the Rows text box). Automatically Update auto-loads the changes in the preview area.

Publish Data to Tableau Server

After you configure the data you wish to visualize, you can publish the Data Source to a Tableau Server instance. In Tableau Desktop:

  1. Click Server -> Sign In
  2. Enter the URL for your Tableau Server
  3. Authenticate with Tableau Server credentials
  4. Click Server -> Publish Data Source and select your data source
  5. Click Publish
