Hey Ali,
This is professional work you're asking for...
I'll give you an example using the Satimage.osax AppleScript Extension, because it didn't take me too long to design and write.
Install the latest version from (here) – particularly if you're using macOS Sierra.
The script will ask you to pick a .csv file and will process it into a folder named Split_CSV_File_Output in your ~/Downloads folder.
This script will ONLY work with csv files where the sort field is the FIRST field of the record – like you've shown in the image you posted.
