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
