Add dashboard extensions directly in Tableau: New in 2021.1

You no longer have to leave Tableau to add extensions

  • In Tableau 2021.1 the extension gallery is built into the tool, so you can drag the extension object onto a dashboard and browse categorised extensions without leaving Tableau
  • Sandboxed extensions (marked with an icon) run on Tableau's own infrastructure with no internet access, while network-enabled extensions run on third-party servers and rely on trust
  • The Tableau-made Filter Bookmarks extension can act as a reset button, remembering the dashboard's initial state and reverting all filters with one click
  • Each extension page shows version compatibility, hosting details and terms of service, which admins should review before deploying
  • Admins can enable or disable specific extension types in server and online settings, which is why you may not see the feature even on 2021.1

Tableau 2021.1 builds the dashboard extension gallery directly into the product, so you can browse, preview and add extensions without leaving Tableau to hunt for a file, and it's worth understanding the security distinction between sandboxed and network-enabled extensions before you rely on them.

Demoed on the default Superstore sample workbook, without connecting to any external data source, just to show how the extension object and gallery behave in a plain dashboard.

The Breakdown
  • Extension gallery is now built in 0:34

    Drag the extension object onto a dashboard and you get a searchable gallery browsable by category (new vis types, custom filters, advanced analytics and more) instead of having to source a file externally.

  • Check for the sandboxed icon 2:20

    An icon on an extension's tile means it runs inside Tableau's own sandboxed infrastructure with no internet access, so only your organisation and Tableau are involved; extensions without that icon run on a third party's own server and involve an element of trust in whoever hosts it.

  • Review the extension's detail page first 3:40

    Clicking into an extension shows version compatibility, hosting details, terms of service and a demo — worth checking, especially as an admin, before deploying it on a live dashboard.

  • Configure an extension like a mini web app 4:22

    Once added, an extension opens a configuration panel running inside an embedded browser window, where you can set labels, colours and behaviour to match your dashboard's styling.

  • Use Filter Bookmarks as a reset button 6:41

    This Tableau-built, sandboxed extension remembers the dashboard's state when the extension loads and reverts all filters back to that state on click — a clean alternative to telling users to refresh the browser or reopen the workbook.

  • Export All extension for exporting sheets 7:18

    A non-sandboxed, community-built extension lets you pick and order dashboard sheets and export them straight to Excel; because it's not sandboxed, it relies on a third-party server rather than Tableau's own environment.

  • Admins can restrict which extensions run 9:11

    Server and Online settings let admins enable or disable extension types (for example, allowing only sandboxed ones), which is why the gallery might not appear even on 2021.1 — it's often locked down pending security review.

Worth Knowing
  • Network-enabled extensions send data to a third-party server, and that server's operator may not even be the company that built the extension if they use other services underneath
  • Tableau's own sandboxed extensions have reportedly been security tested by a third party, giving more confidence than an arbitrary network-enabled one
  • Extension sizing behaved oddly in the demo (no auto-compression, minimum height quirks), which may just be a launch bug
  • This isn't a brand-new capability — extensions have existed for a while, but having the gallery built in and one click away is what makes them genuinely discoverable
Use It When

Reach for this when you want dashboard capabilities Tableau doesn't natively offer (a reset button, custom exports, new chart types) and want to browse vetted options inside Tableau rather than sourcing extension files yourself; as an admin, use the security detail to decide which extension types to allow.

How this Rollup was made provenance & method
