As the name suggests, this website is about sharing knowledge about excel. This website is an educational website for code learning. But friends this website is not free. You will have to Rs.4000 for beginner Excel course and Rs.5000 for expert Excel course. There are also other programs on excel.
They provide books for various courses through which you can expand your knowledge about excel.
You can download some books like pivot charts and pivot table for free of cost. You can also download other projects as well.
It takes few seconds to load and the website has great content also. Registration is required if you are a new user. I would recommend you to use this website if you want to learn about Excel but you have to pay fee for learning.
