Create a Web data Connector

Web connectors are tools to fetch data online from databases that might be public or private. In this example a web connector that is written in JavaScript is introduced that is able to fetch any CSV file online.

The web data connector is located at: https://myousefi2016.github.io/fetchCSV.html

In order to use this web connector and fetch the data from New York Times repository for COVID-19 cases, open a Tableau Desktop and from Connection section, choose Web Data Connector:

And then in the opened window, copy and paste the the address of the developed web data connector to the address bar shown below.

Finally, in the next page, when it asks for the address of the dataset, copy and paste this address for fetching the COVID-19 cases across the US counties from New York Times repository without any HTTP or HTTPS.

Address for the file: raw.githubusercontent.com/nytimes/covid-19-data/master/us-counties.csv

After successful fetching of the data, you should see the loaded data in Data Source pane.

The workbook to reproduce this web data connector is shared here: https://bit.ly/37FF0rm
