Hi @DSL24,
We already have two books about converting from SAS to KNIME and Excel to KNIME. But no Alteryx to KNIME.
Maybe our online courses would be a fast option for learning KNIME for you? We have a free e-learning course, regular beginners and advanced online courses (Starting January) and the fastest way to get to know the KNIME community is our KNIME Summit.
And you are actually already in a great place to learn more about KNIME: We have a great community in the KNIME Forum 
Let us know if you need any help.
Best, Iris
