Sankeys, chord diagrams, supertables, KPI cards with real sparklines: the charts Tableau cannot draw on its own, built as extensions, hosted in your account, ready to drop into a dashboard. Plus the hands-on course that teaches you to build the next one.
Or host your own extension free: drop a folder, get a .trex.
"The new skill was great. I went from zero to a working dashboard in one initial prompt. I liked some of the standards that were baked in without having to discover them throughout, like creating 2 manifest.trex files for dev and prod."
Michael McCusker, Tableau Tech Lead

See the workshopsUpload an extension folder or a .zip. You get back a manifest that points at a real HTTPS URL, with the certificate and the uptime handled. Flip the same extension between your dev server and hosted without editing the manifest.
Host an extensionBlank box, no message. FD722608. An extension that loads fine on your desktop and dies the moment it's published. Every one of these has a specific cause and a two-minute fix. Here they are, in the order you'll hit them.
ReadIt's 20 lines of XML doing one job: pointing Tableau at a URL. Here's every element, why the order matters, and the empty tag whose absence breaks more first loads than anything else.
ReadTwo different things with confusingly similar names, different manifests, and different APIs. Pick wrong and you rewrite from scratch. A decision you can make in about ninety seconds.
ReadEverything here comes out of extensions that actually shipped: the errors are ones that cost me an afternoon, not ones I found in the docs. New pieces land as the work throws them up. Leave your email and I'll send the next one, no more than that.
