The #PreppinData playlist has been updated through 2023 Week 22! If you haven’t tried it yet, PreppinData is a Tableau Community Project that aims to help people learn and maintain data prep skills.
If you are new to #powerquery, I highly recommend the website Powerquery.how. It is a great resource put out by Microsoft MVP Rick de Groot. You can also visit his website BI Gorilla. He is a great resource for learning M, the language behind #powerquery.
