Challenge 2 - Split File and Save Into Subfolders A pharmaceutical company used to keep its sales data in a CSV file. They ask for your help to split the data into monthly CSV files and to save them into different subfolders, where each subfolder corresponds to a year. As an example, the data for January 2015 should be stored in a file named 2015/January.csv. In your solution, remember to save the files and subfolders in the workflow data folder.
