Hi Huda,

As per my understanding, you want to read an Excel file in MATLAB GUI code.

To achieve this, you can follow these steps:

• Use the "uigetfile" function to allow the user to select the Excel file.
• Use the "readtable" function to read the data from the Excel file.

Please refer to the below sample code snippet that demonstrates how to read data from an Excel file:

% Allow the user to select the Excel file
[filename, filepath] = uigetfile('*.xlsx', 'Select the Excel file');
% Check if the user canceled the selection
if isequal(filename, 0) || isequal(filepath, 0)
    disp('File selection canceled');
else
    % Read the data from the Excel file
    data = readtable(fullfile(filepath, filename));
    % Now "data" contains the content of the Excel file
end

Please refer to the following MathWorks documentation to know more about:

• ‘uigetfile’ : https://www.mathworks.com/help/matlab/ref/uigetfile.html
• ‘readtable’ : https://www.mathworks.com/help/matlab/ref/readtable.html

I hope this resolves your query.

Best Regards,
