WARNING:It's easy to create views that Tableau cannot accurately render in .csv format output. Most views have complex structures that cannot be rendered in .csv format. The software gives no warning when this condition occurs and the .csv output that results is unpredictable.
Thecsvoption is also variously known ascrosstaborcrosstab to Excelon some DSA/Tableau screens and in documentation.
The output tocsvmust be a simple table withcolumnlabels from a single view. Do not putrowlabels, totals or other so-called "crosstab" features in the view.
We recommend mentally translating "crosstab" to "raw data in a widely used format".
Earlier versions of DSA AD did not allow this option because of the unpredictable nature of the output.
Use Export Data instead of Crosstab
On Tableau Web Server version 2020.2.3 Export > Data may produce properly formatted .csv files while Export > Crosstab will not.
