The data has been provided to you in one combined .csv file showing the sales for all three stores for the last three years. The stores all categorize sales as either retail or wholesale, but they are not consistent in how they do this. The South location uses a code of “R” for retail, or “W” for wholesale. The other locations use “RS” for retail sales or “WS” for wholesale sales. Explain the steps involved in converting the information from the .csv file to Excel, and what steps you will take to assure the data is usable for your purpose.
