Tableau Reader is a free product that anyone can use to viewing Tableau workbooks that were created by licensed users of Tableau Desktop.
This article aims to help you resolve Tableau Reader-related issues.
To make the workbook completely portable for Tableau Reader use, Tableau Desktop saves a snapshot of the data with the workbook in a Tableau packaged workbook, which uses the file extension .twbx.
Error when opening a Tableau workbook
If you receive an error when you try to open a Tableau workbook in Tableau Reader, you might need to download the latest version of Tableau Reader.
Cannot open a workbook in Tableau Reader
If you can't open a workbook, or you see an "Unknown data source class '<data-source-name>'" message, you might be trying to open a regular Tableau workbook (file extension .twb) instead of a Tableau packaged workbook (file extension .twbx). A regular workbook (.twb) makes a live connection to data whenever it is opened, so you cannot open it in Tableau Reader.
Extract data message when creating a packaged workbook in Tableau Desktop
You must create an extract in Tableau Desktop before you save the file as a packaged workbook. Tableau displays a warning, asking if you want to stop saving the file so you can extract the data you want. If you are connected to an Access, Excel, or a text-based data source, you don't need to create an extract.
Note: Users cannot open a statistical file-based workbook in Tableau Reader unless you create an extract from the statistical data and save it with the workbook as a packaged workbook (.twbx file).
If you see the above message, follow the steps below to create an extract first and then the packaged workbook.
In the Warning message box, click No to stop saving.
Select Data > Extract.
In the Extract Data dialog box, make any necessary selections to refine the extract. You can also keep the default settings.
In the Save As dialog box, enter a a descriptive name for the extract and save it to the default location, My Tableau Repository\Datasources, and then click Save.
Select File > Save As and save the workbook as a packaged workbook.
