How to insert values into a listbox from selecting data from another listbox

I am creating a GUI to make producing graphs from many different files and data options easier as seen in the image below. To begin, the user presses the Data pushbutton. The folder from which the MATLAB file is located will open. Each excel file within that folder will automatically be uploaded into the Data set 1 and 2 listboxes.

Each of these excel files has 35-40 variables that I want to have broadcasted into the Command 1 (Data set 1) and Command 2 (Data set 2) window. I would like to be able to click the populated excel file in the top listboxes and be able to populate the bottom listboxxes. How do I do this? Thanks.

From my understanding, you want to display the data of selected excel file in Command 1 listbox

This can achieved by adding valueChanged Callback on DataSet1 and following the steps:

function ListBoxValueChanged(app, event)
    % get filename from previous box
    % load the file and process the data
    % convert the data to string and cell 1 D
    % update the list box 'Items'
end
