To extract data from a published workbook on Tableau Public, you can download the data source(s) directly. This allows you to obtain a local copy of the data used in the visualization.
Extracting Data from a Published Workbook on Tableau Public
When you have published a workbook to Tableau Public, the underlying data source is often embedded. Tableau Public provides a feature that allows viewers or the workbook owner to download the data source as an extract file. This is particularly useful for analyzing the data offline or using it in other applications.
The process for extracting the data source from a published workbook involves a few simple steps directly on the Tableau Public website:
Step-by-Step Guide to Extracting from a Published Workbook
Here is how you can extract the data source(s) from a workbook already published on Tableau Public, based on the provided information:
- Navigate to the published workbook. Find and open the specific workbook page on the Tableau Public website.
- Select one or more of the data sources. On the workbook page, there is typically an option to view or interact with the data sources. You will need to select the specific data source(s) you wish to extract.
- Choose the Action button. Look for an 'Action' or similar button associated with the data source area.
- Select Extract. From the options presented under the Action button, choose 'Extract'.
Following these steps will typically initiate the download of the selected data source as a Tableau Data Extract file (.hyper).
Why Extract Data from Tableau Public?
Extracting data from a published Tableau Public workbook can be beneficial for several reasons:
- Offline Analysis: Work with the data locally without needing an internet connection.
- Use in Other Tools: The
.hyperformat is versatile and can be used in various data analysis applications, not just Tableau. - Local Backup: Keep a local copy of the data source used in your published visualization.
It's worth noting that creating data extracts (.hyper or .tde files) before publishing is also a common practice done within the Tableau Desktop Public Edition application to improve workbook performance. However, the process described above focuses on extracting from a workbook that is already published online.
