Microsoft Excel - Power Query
What is Power Query?

The Value is in the Refresh
While there is certainly value in the initial analysis, the real value in any BI solution comes from the refresh. When your boss comes to you and asks you to update the solution it took you hours to build and gives you a deadline of 10 minutes, you need to be able to say "Yes, I've got this."
