AI made charts cheap. It did not make them governed, secure, or distributed. That is what Tableau is for, and extensions are where the two meet. You bring sentences. Claude brings the code. Tableau gets the chart it could never draw. Nine hands-on lessons, at your pace, on your own machine. No web-dev background, no watching someone else do it.
Give an analyst an extension and they have insight for an hour. Teach them to direct the building and they have insight forever.
(And sometimes a huge raise. Not guaranteed. It happens.)Each card is a lesson: the thing you build, and the move you learn doing it. Lesson 1 is free, end to end. Click it to start; the rest come with the course.
Grab a hosted .trex and load a real viz extension into your own Tableau, in five moves. No account, no code.
Point Claude at the extension docs so it writes the code you describe, not the code you hand-type.
Turn one plain-English sentence into a working custom mark, then refine it by talking, not coding.
Make the build prove it works with receipts, then break it on purpose before a dashboard does.
One accent, one argument: the edit that turns a busy chart into a clear one.
Build a color system your extension applies itself, correct in both light and dark.
Ship an extension that reads field names only, written to survive a security review.
Bake your brand into the builder so every extension comes out on-brand by default.
Put it at a real URL, drop it on a dashboard, and turn on usage to see who actually opens it.
You are not learning syntax. You are learning what you can describe, and how to make sure it actually worked.
Each lesson opens on the finished extension, running in your browser. You know what "done" looks like before you start.
You direct Claude with copy-paste prompts. It writes the files; you run them on your own machine.
The move that gets you the raise: make Claude verify with receipts, then break the thing on purpose before a dashboard does.
Host it at a real address, share it, put it on a dashboard, and turn on usage so you can see who opens it.
A lesson is a workbook; a step is a sheet. Lesson 1 is free end to end and most lessons open free; the four with the biggest payoffs are course-only. One key unlocks everything. Click any title to start it.
You do not have to take anyone's word for it. Go touch the real thing.
The whole first workbook, live, no signup. See exactly how a lesson feels before you commit.
Start it →An extension built from an empty folder in a live workshop. The lessons are the same builds, hands on your keyboard.
See the workshops →Every extension you will build, running live on sample data. Swap the dataset, drag the sliders.
Open the demos →Lesson 1 is free end to end, most lessons open free before their paywall, and the four biggest are course-only. The full course unlocks with one key. Every tier below is on the store today, one payment, yours to keep.
No. That is the entire point. You describe what you want in plain English; Claude writes the code. What you learn is how to describe precisely and how to check the result.
Tableau Desktop or the free Tableau Public, a browser, and Claude (Claude Code, or claude.ai with copy-paste). The free TableauOps skill. That is it. Lesson 2 sets up the tools with you.
No. Tableau Public is free and takes extensions. The lessons note the fallbacks wherever it matters.
Lesson 7 is exactly this. You control what leaves your machine, and usually it is only field names, never the values. There is a pre-flight you will run by habit.
Everything runs locally first (localhost), and hosting is a standard HTTPS URL. Nothing needs an install you cannot do yourself. The privacy lesson is written to survive a security review. If your organization cannot approve an outside URL at all, an Enterprise license puts the extensions on a host you control.
Workshops are watching: a live build, free, on YouTube. Lessons are doing: the same builds with your hands on the keyboard, at your pace, with every prompt written out. See the workshops.
You redeem a course key into your free ext.tableauops.com account, the same way the Extension Kit works. It unlocks all nine lessons at once and remembers you.
Yes, the promise above. If you do not ship something you are proud of, you get your money back. Just email.
