How do I connect Tableau to OpenSpending?

Execute the following steps to connect Tableau to OpenSpending. You only need knowledge of Tableau and your own business.

OpenSpending is an online web service on the budget and spending of governments in the Netherlands. It includes data from various sources, including IV3 of CBS.

No technical knowledge is needed nor knowledge on the OpenSpending APIs to connect OpenSpending to Tableau. This step-by-step plan will tell you exactly which steps you need to go through on Invantive Cloud to create your own Azure data warehouse with data from OpenSpending.

The steps to connect Tableau to OpenSpending are:

  1. Register an Invantive Cloud account.
  2. Create a OpenSpending database.
  3. Make the OpenSpending database available through the Tableau OData connector.
  4. Connect Tableau to OpenSpending through the connector.
  5. Load data from OpenSpending into Tableau.

Invantive Cloud offers a OpenSpending connector to download data from OpenSpending into Tableau, but there are over 75 other connectors available also for SQL, Power BI, Power Query, Tableau and Azure Data Factory.

Do you have a large environment? For effective downloads, you can of course also filter the data.

When you are having questions, please check the forums for OpenSpending. Every organisation is entitled to 1 hour of free training to help you get started. This free hour also applies to free plans.

You now have a login code on Invantive Cloud with which you can set up the connection with OpenSpending and numerous other platforms. You will use the same Invantive login code and workflow for all other platforms.

Create OpenSpending database

In this step, we set up a database with data from OpenSpending. The database is "virtual" because it is not a traditional database, but is fed real-time from OpenSpending. Invantive Cloud provides Tableau with a real-time link to OpenSpending. The database will be used for all your OpenSpending reporting with Tableau. So you only need to perform these steps once.

  1. Click the Add Database button. Add database.

  2. Select OpenSpending from the list. Select OpenSpending connector.

  3. Please fill out the form with login information for OpenSpending.

  4. Select the OK-button.

Congratulations! You can now process data from OpenSpending within the Invantive Cloud website. You can do this for example with the interactive SQL editor.

Grant connection from Tableau access to OpenSpending

To retrieve the data from Tableau we create a link via Invantive Bridge Online. This creates a "bridge" between the cloud of Invantive and the standard OData connector that is available in every version of Tableau. You do not need to install anything locally: no connector, no ado.NET provider and no Tableau add-on neither.

Execute the following steps to safely use the data from OpenSpending outside of Invantive Cloud:

  1. Next to the database you will find an orange text requesting you to allow access from your current location (IP address). Select the nearby orange button.

  2. You can completely disable IP address checking by entering an asterisk ("*").

You are now ready to import the OpenSpending data into Tableau.

Configure Tableau connector for OpenSpending

You will now pull in Tableau data from OpenSpending through the established link.

Please note again that Invantive Cloud under the hood handles all complexity such as setting up credentials such as a refresh token, acquiring an access token, optimizing and parallelizing access, accessing an API within the rate limits, scopes and security restrictions. There is absolutely no need for knowledge on complex technical topics such as OAuth access tokens or API.

Execute the following steps:

  1. Start Tableau and choose "More..." from the "To a Server" menu on the left menu "Connect". Prepare import of OpenSpending data into Tableau.

  2. Search and select the OData connector.' Select the Tableau OData connector to import data from OpenSpending.

  3. Enter in the window the Bridge Online URL of the Tableau database. This URL containing the data can be found in the Database-form of Invantive Cloud. Choose authentication type "Username and Password". Enter the Invantive Cloud user name and password. OData URL for OpenSpending with log on credentials

  4. The list of available OpenSpending tables appears. Select the desired tables and construct your Tableau dashboard. Select OpenSpending tables and process them in Tableau.
