Tableau is a software application which is used to develop business based documents which are usually interactive data visualization files. When a workbook is created by a user using this application the file format given to the stored file is TWB.

The file format is used to store the data added to the file by the user in such way that it can easily be changed or manipulated by the user whenever required. Along with this the different effects added by the user are also saved in the file in such way that they can also be replaced or removed by the user.
