Question

How to use a .tdc file with Tableau Prep.

Environment

  • Tableau Prep
  • Windows and Mac

Answer

Important: Tableau does not test or support .tdc files. These files should be used as a tool to explore or occasionally address issues with your data connection. Creating and maintaining .tdc files requires careful manual editing, and there is no support for sharing these files.

To use any connection customizations with Tableau Prep that were originally set up for Tableau Desktop, copy the relevant .tdc file from your My Tableau Repository\Datasources folder, and paste them into the My Tableau Prep Repository\Datasources folder.
