“AMAZING TEACHER
I love your course and could listen for hours. You distill valuable advice clearly. Found you on YouTube while struggling with LOD expressions; examples helped immensely. Grateful for accessible pricing and free content—your teaching is engaging and generous.

Emeline Courcelle

This course is a must for first-time Tableau users intimidated by data. Jed simplifies Tableau with step-by-step guidance: setup, import data, navigate the UI, and create visualizations. Clear, encouraging teaching—confidence transformed and ready to build. Thanks for making Tableau accessible.”
Adam Lockwood
“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!”
Elizabeth Deterding
“AMAZING COURSE
The course is great! Feels like studying with a friend :) Everything is explained very easily and I am looking forward to the next one!”
Anastasiia Larina
“BEST TABLEAU TRAINING EVER
Totally clear and very well explained with a bunch of examples. All sensible topics – LOD, Actions and Calculated Fields are tackled.
Big Thank You!”
Nicolaie Cozma
“I LOVE LEARNING TABLEAU WITH JED
The best teacher of Tableau I have ever found! I would love to meet Jed someday in real life. I like his sense of humor and the way he explains everything.
Jed much thanx for this course.”
Emilia B Korycka
“JOINS WERE HOLDING ME BACK
Great – this was holding me back but not any more”
Brian Sundermeijer
“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.”
Bryan Nylander
“ONE OF THE BEST EDUCATORS ON PLANET TABLEAU
Jellyman is a fantastic teacher! His lessons are unlike others to say the least!!!
Hats off to his engineering personality and his koool sense of humour (A bit of contradiction there but definitely works like magic on our memory capacity to retain his fun lessons :)”
“AMAZING!
Take this course even if you think you're an expert in Tableau”

MY STUDENTS LOVE LEARNING AND I LOVE TEACHING
“THE LUCK TO HAVE JED AS A TRAINER
This intermediate course answered so many questions I had about how to visualize my data.
You've developed very easy-to-comprehend tutorials based on real-world examples and provided so many tips and tricks that make calculating fields so much faster. Thank You!!
Jed also provides a lot of information on working in the field of data analytics which is a great bonus and provides references for further study in the field of visualizations.
When Jed publishes his next set of tutorials – Tableau Desktop for Experts – I'm definitely signing up.
Thanks Jed for sharing your knowledge and passion for data”
Margot Drewe
“TABLEAU NOOB
I'm coming into this course with absolutely no knowledge or previous experience with Tableau (or data analytics in general).
Jed does an amazing job of breaking down these concepts into its most simplistic form.
I love it so far and I'm sure you will too. Looking forward to the rest of the Bundle”
Raymond Hahn
“A MUST FOR ALL TABLEAU LEARNERS
Still well worth my $$$. Been learning and using Tableau for three years now and Jed still has the clearest, easy to follow and understand lessons – long enough to cover the subject, but short enough to keep it interesting”
Bryan Nylander
“EXPLANATIONS I CAN UNDERSTAND
Thank you Jellyman! You have developed a fun and easy to understand course that simplifies the processes in Tableau, well for me anyway.
I've done a few courses to try and comprehend Tableau and this one works for me. Can't wait to learn more in the intermediate course”
Margot Drewe
“THE LUCK TO HAVE JED AS A TRAINER
Rarely I have seen trainers to be so effective as Jed is.
All his success and effectiveness is coming from his level as an expert and associated field experience,
but also from his joy to share knowledge with others.”
Nicolaie Cozma
“AGILE PROJECT DEVELOPMENT
I enjoyed it and agree that these concepts are important!
I could listen to this topic in the background while running other jobs and multi-tasking.
Thanks for including it.”
Elizabeth Sogge
“LOVE THE DETOUR
Just finished the project management sessions and what a whopper!
In fact I was bragging to my coworker today about learning about Waterfall.
This section was a bonus to this course and one of the things I like about the presentations –
how to use Tableau in your career, not just make pretty dashboards.
As someone trying to do just that, this talks to me and I appreciate the insight into such nebulous topics as Impact.
Looking forward to learning more”
Bryan Nylander
“AWESOME!!!
I have really enjoyed the course and found the instruction clear and easy to follow.
Having never used Tableau before, I feel much more confident in doing so.
Looking forward to putting into practice what I've learned and completing the additional courses”
K Jones
“5 STARS!!
Love this course and highly recommend it!!”
Fred Wooten
“BRILLIANT EXPLANATION STYLE
I'm loving the course so far. I'm taking it as a refresher as I was a beginner–intermediate Tableau user but haven't used it in a long time.
I saw one Jellyman YouTube video about LOD calculations & loved the style of teaching so signed up for the course.
The concepts are explained so clearly & the format is slick & engaging.
I already know I will quickly surpass my previous Tableau skillset doing this course. Thanks!”
