About Tableau Web Data Connector

Tableau Web Data Connector (WDC) enables you to connect to the required web data source accessed via HTTP and use Tableau to scrape, analyze and visualize the data. Tableau has already created WDCs for different platforms like Tableau Twitter web data connectors. But you can also create your own WDCs, for example, to get data from Instagram periodically and visualize it. All you need is to know how APIs operate and to have some basic skills of a “Google developer”.

How to create Tableau WDC

The WDC principle is simple. The HTML part is what we see, and to connect to web data we use the JavaScript code that reads JSON response and passes data on to Tableau. You can connect to any data from the web services, REST APIs, and JSON data, or any other sources available over HTTP. For building your own WDC you need:
  • Git,
  • WDC SDK to build connectors,
  • Web server for your WDC.
Once you have all the required staff, follow the instructions on how to build Web Data Connectors or look for the SDK code samples and supporting documentation on the Tableau Community page.

How to scrape with Tableau?

There are two ways to process data with Tableau. First, you can upload your collected data file to Tableau Desktop. Secondly, you can connect a data source (website analytics, social media pages, or any other open database) directly to Tableau with WDC (Tableau Web Data Connector). Tableau will process the incoming data and visualize it in a format convenient for you.

How to scrape data from the Tableau dashboard?
