There is a small learning curve with Make, which is why I created this basic navigation video to help. I also provide the links to a few other Make training resources there as well. For example, to instantly trigger your Make scenarios from Airtable, check out this thread.
@A-B Alternative would be to use a Airtable specific Tableau Web Data Connector and avoid using a third party tool.
Airtable Labs created their own, which is free but limited in some ways.
We also have our own (paid) tool that supports many-to-many relationships between tables (including the Multiple Users and Multiple Linked Records fields). So no matter how the tables in your base are structured, you can export the data into Tableau.
We've created our own Airtable Tableau Connector to solve this problem - thought it might be useful based on the chat here. It allows you to export any Airtable data securely into Tableau in a few simple steps
The nice part of using a Connector is that all the data flows directly from Airtable to Tableau without ever touching third party servers.
