I explain that Tableau is deprecating the .TDE (Tableau data extract) file format in March 2023 with the 2023.1 release, leaving the Hyper file as the only extract type. I walk through the community post from the Hyper team, clarify the confusing terminology, and cover what server admins, Tableau Online and Tableau Public users need to do.

## Key takeaways

- The .TDE format will no longer be supported from the 2023.1 release in March 2023, with the Hyper file becoming the only extract type Tableau produces.
- People loosely say "Tableau data extract" to mean a .TDE, but since version 10.5 (2018) the actual file produced has been a .Hyper file, so for most users this change is largely terminology.
- Server admins can find lingering .TDEs by filtering data sources for the Tableau Data Engine connection type, and from 2022.1 can use Tableau Services Manager commands to block .TDE publishing.
- Tableau Online users need do little, as Tableau will restrict .TDE publishing from June and auto-convert old files; there is also a conversion script on Tableau's GitHub.
- Tableau Public likely holds the largest library of old .TDEs, so workbooks built before version 10.5 that haven't been touched are the ones most affected.
