In Tableau, data sources are the foundation for all your visualizations and analyses. They allow you to connect to and import data from various sources, such as databases, spreadsheets, and cloud services.
To replace a data source in Tableau, first open your workbook and navigate to the “Data” menu. Select “Replace Data Source” and choose the current data source you want to replace. Then, select the new data source from your available connections. Tableau will attempt to match fields between the old and new sources; verify and adjust these mappings as necessary to ensure your visualizations update correctly.
In this article, you will learn how to replace a data source in Tableau. The process will be broken down into steps with examples and demonstrations to help you better understand the concepts.

Step 2: Load the Data Source To Replace The Existing Data Source
To replace the data source with a new one, you must load a new data set to Tableau.
To do so, click on Data and select New Data Source.
After loading the new data source, you’ll see it in the Data pane.
Step 3: Replacing the Data Source

How is Replacing a Data Source Useful
Replacing a data source in Tableau offers several advantages, particularly in scenarios where you need to update or enhance your visualizations with fresh or more relevant data.
You may want to replace your existing Tableau data source due to any of the following reasons:
1. Maintaining Consistency
By replacing a data source, you ensure that your visualizations continue to be based on the most current and accurate data available.
This consistency is crucial for making informed decisions and maintaining trust in your analytics.
2. Saving Time and Effort
Rather than creating new visualizations from scratch, replacing a data source allows you to reuse existing visualizations and configurations with updated data.
This can save significant time and effort, especially for complex or extensive dashboards.
3. Enhancing Flexibility
As your data needs evolve, you may need to switch to more suitable data sources or combine multiple sources for a comprehensive analysis. The same data source might not be relevant in a time in future.
Tableau’s replace data sources functionality empowers you to adapt to these changes without being limited by the original source.
