I have successfully converted from a Tableau .twbx file to .twb and now have a .tde file for the data. How can this .tde be converted to either .csv or .xls(x) ?
Building on @AlexBlakemore 's answer: from Version 10.2.2 there is a feature for Export to CSV. It is non intuitive how to find it: select the Data | (data source name) | Export to CSV :
You can also export to CSV from the Data menu starting in version 10.3.
That command exports the entire data source, while the export commands on the worksheet menu export only the data referenced by the worksheet. Both are useful. One exports the entire data source, the other exports the fields used on the worksheet
The Worksheet | Export | Data (or Crosstab to Excel)' appear to have done the trick: there are now anxlsxand a.csv` file with the relevant dataset included.
