How to Relace Datasource in a workbook in Tableau?

 To replace a data source in Tableau with a different one while maintaining the existing workbook structure, you can follow these steps:

  • Open the Workbook: Launch Tableau Desktop and open the workbook that contains the data source you want to replace.
  • Navigate to the Data Source Tab: At the bottom of the Tableau window, locate the data source tab and click on it to access the Data Source tab.
  • Identify the Current Data Source: In the Data Source tab, find the current data source that you want to replace. Take note of its name and the fields it contains.
  • Connect to the New Data Source: Go to the "Data" menu at the top and select "New Data Source." Alternatively, you can click on the "Connect" pane on the left sidebar.
  • Choose the New Data Source: Select the appropriate data source type for your new data, such as a file, database, or other supported sources. Specify the connection details and locate the new data source.
  • Map Fields (if necessary): If the new data source has different field names or structures compared to the original data source, you may need to map the fields manually. Tableau will attempt to automatically match fields, but you can make adjustments as needed.
  • Replace the Data Source: Once the new data source is connected and the fields are mapped (if required), right-click on the original data source in the Data Source tab and select "Replace Data Source" from the context menu.
  • Select the New Data Source: In the Replace Data Source dialog box, choose the new data source you connected in step 5 from the available options.
  • Verify and Update Field Mappings: Tableau will attempt to map the fields from the old data source to the fields in the new data source. Review the field mappings and make any necessary adjustments to ensure the correct mapping of data.
  • Apply Changes: Click on the "OK" button to replace the data source. Tableau will update the workbook to use the new data source while maintaining the existing worksheets and visualizations.
  • Validate and Update Worksheets: Review the worksheets in your workbook to ensure that the new data source is functioning as expected. Check that the data is correctly displayed and any calculations or visualizations are updated accordingly.

By replacing the data source, you can seamlessly switch to a new data set without having to recreate or modify your existing Tableau workbook extensively.
