Can MATLAB save the Profiler results table (Function Name, Calls, Total Time, Self Time) to a text file or a spreadsheet?

I need this to merge and compare Profiler results from different software versions.

info.mat

I get no error:

info = load("info.mat").info;
infotab = struct2table(info.FunctionTable);
infotabMain = infotab(:, ["FunctionName", "NumCalls", "TotalTime", "TotalRecursiveTime"]); % main table in profile viewer
infotabExc = cell(height(infotab), 1); % execution time per each subfunction 
for i = 1:height(infotab)
    infotabExc{i} = infotab.ExecutedLines{i};
    infotabExc{i} = array2table(infotabExc{i}, ...
        'VariableNames', {'Line Number', 'Calls', 'Total time(s)'});
end
% show me what you got

Yes, it can be done realtively easy with profsave(profile()), e.g.:

    profile on
    x = linspace(0, 1, 2e3);
    y = sin(2*pi*t)+randn(size(x));
    plot(x,y), grid on
    profile off
    % All html files are saved in your current directory and inside a folder called: MY_Profile_results
    profsave(profile('info'),'MY_Profile_Results')
