I am using matlab online. I have 2000 dat files as data. Whenever I run the code, the folder appears and I have to manually select the data file. I want to loop over all the data and automatically save the plot. How to do that.

Try this:

files = dir("*.mat");
for i=1:length(files)
    clf;
    file = files(i);
    load(file.name);
    plot(x, y);
    [~, fname, ~] = fileparts(file.name);
    outfile = [fname '.png'];
    saveas(gcf, outfile);
end
