Useful Excel for Beginners’ is a free on-demand video-based course tailored for beginners who are interested in learning Microsoft Excel.
The course covers the concepts and features that I believe will help you get started and become a functional user of Excel.
Chandeep, my friend, runs the site Goodly.co.in and is an Excel Expert and trainer. He has been training, consulting and blogging since 2013.
I learn a lot from his blog posts about Excel tricks in Data Visualizations and Dashboards. He has a free course on Excel Charts and premium training on Excel, Business Intelligence Dashboards and even Power Query.
At PowerSpreadsheets.com , my friend J, provides articles that focus on making everyone an Excel Power User.
I would recommend his site for tutorials on VBA/Macros.
He has both free and premium courses as well.
