Hi!
I'm taking the training Develop for Marketing Cloud. The training https://trailhead.salesforce.com/content/learn/modules/marketing-cloud-contact-management/learn-about-data-extensions?trail_id=develop-for-marketing-cloud refers to a lot of examples but in order to see them, I need to import some data and then I'll be able to see sample attributes and how they are connected in Data Designer. Is there a way to get the test data that I can import and play with?
