How can I use multiple files from uiget with importdata?

I'm trying to load in several files from a folder using uiget so that it is user friendly for other folks. Right now I have the following code:

Import data
[filename,pathname] = uigetfile({'*.*', 'All Files (*.*)'},'Pick a file','MultiSelect','on');
delimiterIn = ',';
A = importdata(filename, delimiterIn);

When I use this I get the following error:

Error using importdata (line 136)
Unable to open file.

Error in LoadSQMData (line 16)
A = importdata(filename, delimiterIn);

It seems that my issue may be because the multiple files load in as a cell, but when it is a single file it loads in as a character struct. I'm able to figure out how to change the cell to a char, but I can't figure how to use importdata on this alteration. Any thoughts on how I could get this work?

Thanks in advance!

You have to use a for loop to load files one by one.

delimiterIn = ',';
[filename,pathname,~] =  uigetfile({'*.*', 'All Files (*.*)'},'Pick a file','MultiSelect','on');
if isequal(pathname,0)
    % No file Selected
    disp('No file Selected!');
    return;

elseif iscell(filename)
    % Multiple Files Selected
    FilesCount=length(filename);
    for loop1=1:FilesCount
        sFileName=filename{loop1};
        if ~isequal(sFileName,0)
            sFullFileName=fullfile(pathname,sFileName);
            A = importdata(sFullFileName, delimiterIn);
        end
    end
else
    % One File Selected
    sFileName=filename;
    sFullFileName=fullfile(pathname,sFileName);
    [~,sModelName,~] = fileparts(sModelName);
    A = importdata(sFullFileName, delimiterIn);
end
