I have written a MATLAB script and I want to convert my existing code to a GUI using app designer. The code is off gunshot localization with 7 microphones array. I am new at using MATLAB and app designer. so please help me to convert my script into GUI using App designer. It will be appreciated.

The first step is to convert your code to a function. Then you can design your GUI to gather the necessary inputs for that function, that is after all the point of a GUI.
For general advice and examples for how to create a GUI, have look at this thread.
