"response": "The provided Python script has been significantly refactored to include a graphical user interface (GUI) using PyQt5. The script now features a simple window with buttons to select input and output directories, as well as a button to start the merging process. The GUI provides feedback through message boxes and prints statements in the console. The core functionality of merging Excel files remains intact but is now encapsulated within a class for better organization and reusability."
