File Types

Extension Tableau File Type Purpose
.TWB Tableau workbook This file type stores visualization without source data
.TWBX Tableau package workbook Sort of extracted data and visualizations for viewing in Tableau, Tableau online or Tableau reader. This file type keeps the data with the Tableau file. So if you want to share the data, and visualization, you can do that with a .TWBX file
.TDS Tableau data source Stores the server address, password, and other information required to access a data source
.TBM Tableau bookmark And that stores a connection to a worksheet in another Tableau workbook
.TDE Tableau data extract Stores Tableau data as a filtered and aggregated extract. So if you have a large data set, and you want to filter down to a subset of that data, and perform some aggregate calculations, you would save it as a .tde


  • Tableau uses a workbook and sheet file structure, much like Microsoft Excel
  • A workbook contains one or more sheets, each of which can be a worksheet, dashboard or story
  • You can use workbooks to organise, save, share and publish your results
  • When you open Tableau, a blank workbook is automatically created
