“EXCELLENT COURSE
Jellyman is an excellent teacher! His content is interesting, applicable and well-explained.
He has clearly thought about the way people absorb information and doesn't gloss over any assumed knowledge like many other courses do. He has taken the time to go through methods & concepts step by step so it's almost impossible not to learn!

Great – this was holding me back but not any more

“STILL LEARNING THINGS
I was wondering why we were just now covering joins when it's something I felt essential enough to be a beginner subject. Then you delved into joins versus relationships versus blends and it became much clearer – this was more complex than an entry level subject.
Great explanations all around and I have a better understanding of when to use which tool.
Update: Just finished LODs. Mind continues to be blown! Can't recommend this course enough.

No you don't! I designed it with Tableau Public Free Edition in mind. For places where I demonstrate capabilities in the Paid Version, I simply showcase it. But you don't need to repeat to proceed.
No, you don’t. Tableau’s drag-and-drop interface makes it accessible for complete beginners. You’ll learn how to explore and visualize data without needing coding knowledge.
Tableau connects to a wide variety of sources: Excel, CSV files, Google Sheets, SQL databases, and cloud platforms. This flexibility lets you practice with almost any dataset you have.
- Public – Free version, but your dashboards are saved online for anyone to view.
- Desktop – Paid professional version with full features and the ability to save locally.
- Online/Server – For sharing and collaboration with teams or organizations.
Not at all. Tableau automatically handles most calculations like sums, averages, and percentages. Having basic math knowledge helps, but the software does the heavy lifting.
Yes. Tableau can manage millions of rows of data, though performance may depend on your system and connection type. Beginners typically start with smaller Excel or CSV datasets before scaling up.
This is where your journey begins here at Jellyman Education. You'll get a quick feel for what Tableau is and why it's such an amazing tool.

You're now delving into some of the highest and most complex operations you'll find in Tableau. LOD's, Joins, Unions, Big Data, Blending, Parameters, Sets, Advanced Dashboards and Custom Visualizations. WOW INDEED!!!!
Now it's getting really fun. Think of Tableau Cloud as the digital cafe where you and your friends meet up to share stories, information, dashboards, data, results and more. It's the future of Data Sharing in the Industry today.
With Visualizations through Tableau Desktop and data sharing through Tableau Online, it's time to tackle Advanced Data Cleansing using Tableau Prep. This is one of the most enjoyable tools you'll find especially if you clean data all day long!
