What is a TDE file?
A TDE file is a data file used by Tableau Desktop, a whiteboard visualization and analysis application. It contains data extracted from an external data source, such as a Microsoft Excel workbook, Microsoft Access database, or a .CSV file. The data may also be extracted from a remotely connected data source.
TDE files are used for storing external data in a format recognized by Tableau software. They are useful for keeping local copies of data so that the data does not have to be reimported from the external source again.
