Apart from the 14day trial license are there any license for people who want to learn Alteryx?
Are you in school with a .edu email? Are you using Alteryx to support a charitable organization? These are ways to get a free license from Alteryx For Good (AFG).
As I also understand it, you may use the Alteryx Academy training resources to prepare yourself ahead of receiving a paid or free license.
Cheers,
