Visualize Live Alchemy Data in Tableau

Tableau is a visual analytics platform transforming the way businesses use data to solve problems. When paired with the CData API Driver for Tableau, you can easily get access to live Alchemy data within Tableau. This article shows how to connect to Alchemy in Tableau and build a simple chart.

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

Connect to Alchemy in Tableau

Open Tableau and click More under Connect -> To a Server. Select "Alchemy by CData," then configure the connection and click "Sign In."

Start by setting the Profile connection property to the location of the Alchemy Profile on disk (e.g. C:\profiles\Alchemy.apip). Next, set the ProfileSettings connection property to the connection string for Alchemy (see below).

Alchemy API Profile Settings

After obtaining your API key, set the following connection properties:
