The result of data analysis in Tableau can be saved in different formats, to be saved and distributed. The different formats are referred as various file types and they are identified by various extensions. Their formats depend upon how they are created and for what purposes they are utilized. They are altogether stored as XML documents, which can be opened and altered.
Tableau Workbook (.twb):
This record type is likely the most well-known that you will see and make when working with Tableau. It is in XML format (have a go at altering it in a content tool) and contains all the data on each sheet and dashboard that is contained inside your exercise manual. Data, for example, what fields are being utilized as a part of each view and how measures are being aggregated, the formatting and styles applied and some other setup you've made to a sheet or dashboard. It likewise incorporates information source connection information and any metadata you have made for that connection. it is saved with the extension .twb
Tableau Packaged Workbook(.twbx) :
Tableau Workbook (.twb) as depicted above holds all the data Tableau requires to draw your viz, it does exclude the information itself. A Packaged Workbook how ever combines the data in an work data and groups it with any local data – i.e. information that is not on a server. You can consider it as a zip file, and if you rename the .twbx file as a zip file you can open it with windows to see the .twb and the corresponding data files . A .twbx will likewise incorporate any custom pictures, and additionally any custom geocoding you may have utilized as a part of your work.it is saved with the extension .twbx
Tableau Data Source (.tds) :
When you connect with your data for the first time, you may have a little bit of data "modeling" to do – setting the right data types, changing default aggregations, setting default colours, creating some exceptionally figured fields and so on. You are giving Tableau information about the data you will be utilizing – you are setting up its 'metadata'. When you need to connect with this data again, you would prefer not to truly experience this data modeling a moment time so all things considered you can save your metadata as a .tds document (once more, it is spared in XML configuration) and connect your data through this file . You could likewise distribute this file. It is saved with the extension .tds
Tableau Packaged Datasource (.tdsx):
Much the same as the way that a .twb does not contain any of the information but a .twbx does, a .tds document just contains the information about the data, not simply the data itself. A Tableau Packaged Datasource (.tdsx), be that as it may, contains the data too. You would create this type of file rather than a .tds in the event that you needed to share the association data to another person who did not have access to the information. It is saved with extension .tdsx
Tableau Bookmark (.tbm) :
A marginally lesser known Tableau document sort is the Tableau bookmark. This file is somewhat similar to a fare of one single worksheet, which you would then be able to import into another workbook to save you reproducing the view from starting with no external help. Tableau 8.1 introduces functionality with help copy and paste worksheets from one workbook to another , so this file type may become utilized less yet it can even now be convenient in the event that you consistently utilize a specific view in huge numbers of the workbooks. It is saved with extension .tbm
