importing data from csv to sql data warehouse

I have 100s of heavy CSV files and wanted to upload it on Sql Data WareHouse, and then connect it with PowerBI. Whats the best way to do so?

I have referred to this page which talks about using bpc commands, but then it has requirements of UTF-16 and requires tables to be created beforehand, which seems a LOT of effort before we can import 12GB worth of csv file in sql data warehouse. Isnt there a way to drag and drop the data into sql data warehouse or something as easy?

Any pointers appreciated.
