When working with Tableau Desktop, ensuring your data and visualizations are saved properly is essential for efficient analysis and collaboration. Depending on your project and data source, there are several ways to save your work in Tableau. Understanding the options—whether you're saving a live connection, a data extract, or exporting data—can help you streamline your workflow, share your work effectively, and optimize performance.
In this blog, we’ll explore the different ways to save data in Tableau Desktop, how to choose between live and extract data connections, and when to use each method.
1. Save as a Tableau Workbook (.twb)
A Tableau Workbook (.twb) file is a lightweight format that contains all the structure and configuration of your dashboard, including layouts, formatting, and connections to the data source. However, it does not include the data itself. Instead, it links to the data stored externally.
When to Use a .twb File:
When you’re working with live data stored on a server or external database that updates frequently.
When you and your collaborators have continuous access to the same data source.
When the data set is small or frequently changing and doesn't require storage within the file.
How to Save as .twb:
Go to the File menu.
Select Save As.
Choose Tableau Workbook (.twb) and click Save.
Tip: The .twb file is ideal when you don’t need to include data in the workbook, keeping file sizes small and easy to share.
2. Save as a Packaged Workbook (.twbx)
A Packaged Workbook (.twbx) contains everything in a .twb file plus the underlying data. This bundled format is perfect for sharing the entire project, as it packages the data source and workbook together, ensuring your work is portable.
When to Use a .twbx File:
When sharing your analysis with clients or colleagues who don’t have access to the original data source.
When you want to ensure your dashboard and data are always available, even offline.
When your data is stored locally (e.g., in an Excel file or CSV) and needs to be embedded with the workbook.
How to Save as .twbx:
In the File menu, select Save As.
Choose Packaged Workbook (.twbx) from the file type options.
Click Save.
Tip: The .twbx format is ideal for sharing or archiving your work, but keep in mind that the file size will grow as the data volume increases.
3. Switching from Live to Extract Data
When connecting to data in Tableau, you have two options: Live and Extract. A live connection pulls data directly from the source in real-time, whereas an extract creates a snapshot of the data stored locally for quicker access and improved performance.
What’s the Difference?
Live Connection: Data is updated in real time, making it ideal for dashboards that need to reflect the most recent changes.
Extract: Tableau saves a snapshot of the data, improving performance and allowing you to work offline. Extracts are especially useful when working with large data sets or slow data sources.
When to Switch from Live to Extract:
Performance Issues: If you notice your dashboard is sluggish due to the size of the live data set, switching to an extract can speed up performance.
Offline Work: Use an extract when you need to work without continuous access to the live data source.
Data Stability: If your analysis doesn’t require real-time data (e.g., historical analysis), an extract provides a stable snapshot.
Sharing: When you need to share the workbook with someone who doesn’t have access to the live data source, creating an extract ensures the data is included.
How to Switch to an Extract:
In the Data pane, right-click on your data source.
Select Extract Data.
Customize your extract by applying filters or aggregating data if needed, then click Extract.
Tip: You can refresh extracts periodically to ensure the data stays current without compromising the improved performance and flexibility of an extract.
4. Exporting Data
In addition to saving your workbook, Tableau Desktop allows you to export the underlying data in your visualizations for external use. This is particularly helpful when you need to share raw data with others or analyze it in tools outside Tableau, like Excel.
How to Export Data:
Right-click on the visualization or worksheet.
Select View Data from the context menu.
Toggle between Summary Data and Full Data to view different levels of detail.
Click Export and select your preferred file format (Excel, CSV).
When to Export Data:
When you need to share raw data with someone who doesn’t have Tableau Desktop.
To use data in external tools for further analysis or reporting.
To create a snapshot of your data at a particular moment for archiving or documentation.
Tip: Exporting detailed data is useful for audit trails or when presenting exact figures from visualizations outside Tableau.
Conclusion
Understanding how to save your work in Tableau Desktop is key to preserving your analyses and ensuring smooth collaboration with others. By knowing when to use a .twb file, a .twbx file, or when to switch between live and extract data connections, you can optimize both performance and accessibility.
To recap:
Use a .twb file for live connections to external data sources.
Opt for a .twbx file to bundle your workbook with the data for easy sharing.
Switch to an extract for performance gains, offline access, and data stability.
Export your data when you need to share or further analyze raw data outside Tableau.
By mastering these saving options, you’ll ensure your work is always secure, shareable, and efficient.
