Projects like this are really cool in terms of providing different tools for when you need to work with Excel. However, I don't see tools like this or for any other language being widely adopted.<p>Here is why:<p>1 - Most of the times, people are going to use Excel for basic data analysis with the built-in functions.<p>2 - If you need to do more complex tasks, you have two options:<p>* You know Clojure, Python or other programming language so you use the default environment for these languages to accomplish the task you need, or<p>* you know or learn VBA and stick with it because it's already built-in with Excel.
