Creating CSV Files

Visual Studio Code, Sublime Text, or Atom will all work great for creating CSV files. If you don't have one of these editors installed, try Notepad.exe on Windows or TextEdit on MacOS. Note that TextEdit wants to save data in rich text format default. Be sure to choose Format -> Make Plain Text before choosing File -> Save.
