What? Are you serious? Knowing Excel is knowing A.I.?

YES, absolutely!

Of course, there are some required intermediate steps in between, namely, acquiring or having:
a) proficient skills of Excel,
b) general understanding on A.I. concepts,
c) Machine Learning algorithms (e.g. Linear Regression (the simplest one), Naive Bayes classification & some more) knowledge.

So, belearning always!

Why Excel for Data Mining?
As it’s a very popular productivity software, applying it as a starting point for A.I., Machine Learning and Data Mining is a very good idea.

Excel allows users to work w/ data:
a) in a transparent manner
b) that intermediate results are examined conveniently
c) while some machine learning algorithms can be implemented, e.g. Linear Regression machine learning w/ Excel

Last but not the least, you may find the relations among A.I., Machine Learning, Data Science and Data Mining (w/ Excel) below:
