Trying to load a .txt file in MatLab & save the data in workspace, all through GUI

I'm creating a guide, where I will navigate to a folder, open a .txt file, and it will load the data into the workspace. The data will be an unknown amount of numbers, but in two columns. Later on in another GUI page, I will need to recall the data (hence needing it in the workspace) in order to cary out various math and graphing functions individually. So far this is what I have, but I'm hoping it's a simple answer to my question..

My original code -

global browse
[filename,filepath]=uigetfile({'*.*','All Files'},'select Data File 1');

cd(filepath);

browse = load(filename);

handles.browse = load([filepath filename]);

text = fileread(filename);

set(handles.batman, 'String', filename); %showing file name in box 1

set(handles.robin, 'String', text); %previews file in box 2

EDITS: I have tried inputting an fopen, fscan, and close in various ways put still get random errors with each one. Would setappdata/getappdata work anywhere?

I have tried putting the following between the handles.browse load and the sets, deleting the test=fileread.

handles.browse = fopen([filepath filename]);

data = fscanf(handles.browse,'%f',[12 Inf]);

fclose(handles.browse);

disp(data);

^^ This shows my data in two columns from the file, but does not load to workspace, and I get the following error -

Error using matlab.ui.control.UIControl/set
While setting the 'String' property of 'UIControl':
String should be char, numeric or cell array datatype.

global browse
[filename,filepath] = uigetfile({'*.*','All Files'},'select Data File 1');

browse = load(fullfile(filepath, filename));

Your global variable browse now contains the numeric contents of the file.

set(handles.robin, 'String', cellstr( num2str( browse ) ) )

The data will be converted to a formatted char array, that will be converted to a cell array of strings, and that will be sent to the uicontrol. The uicontrol should have been configured with Max greater than 1 in order to handle multiple lines.
