I'm a newbie. Where should I start to learn about it? Please help me!
Hello @thegioididong ,
You may begin using it, playing around with it.
I recommend you to begin with the interactive lessons:
https://community.alteryx.com/t5/Interactive-Lessons/tkb-p/interactive-lessons
Start with the getting started, if you are an excel user, go to Alteryx for excel users.
Also, you could take a look at the starter kits that are free worflows already created and documented with use cases:
