Data Studio Reporting From CSV

I have a monthly export of data in a CSV format. The data is for activities, bookings, revenue by month. Example attached (had to rename as txt for upload).

I need the ability to upload these files to Google Data Studio for anaylsis including multiple filter, tables and graphs.

I expect to able to filter the data by month, activity, web booking and payment type.
i need to be see trends of activity over the months.

I need to own the Data Studio product so i can make changes. Although there may be further work for you to improve the report over time.
