Analysing jumbled Excel data from multiple sheets

My Data.xlsx

Hi

I have the attached spreadsheet which I have to pull into a usable data set on which to create reports. As you can see there are totals on some sheets and the columns are in different orders for different months. 

What is the best way to automatically create one table with all this information so that it can be used for data analytics.

As an Access developer I thought that Access might be the right thing to use. On the other hand I have heard that Power BI is a powerful way to analyse data.

With such a jumbled set of data what are the best approaches to take?

Thanks
