Tableau File Types

Twb, twbx, tds, tdsx, hyper — know what each file actually holds and you'll stop fighting Tableau's plumbing.

This series walks you through every file type you'll meet in Tableau, from bookmarks and saved data sources through to workbooks and the Hyper extract engine. You'll learn exactly what metadata each file stores, when to package data versus keep it live, and how to reuse sheets and connections across projects instead of rebuilding them. It starts with the basics of bookmarks and builds up to the deprecation of TDE files and a deep look at why Hyper is fast.
