If you're looking for a real ETL-for-dummies, take a look at my EasyMorph (https://easymorph.com). We've made a number of simplifications that specifically target "dummy" users, e.g. columns may mix values of different types (text, numbers, etc.).
Thanks for developing easymorph! Free version helped me through my bachelors degree. It's my go-to tool to introduce people to ETL and similar concepts.
You're welcome! Great to hear it happened to be of help :)
And it's a partner with Tableau? Yeah that sounds pretty good! Thanks for the tip.
Yes, we're partners with Tableau. Just returned from Tableau Conference 2018 in New Orleans where we had a booth.
