Web app not able to perform xlsread/xlswrite

I've compiled a web application with matlab web app compiler. In my code I use both .mat files and .xlsx files which are located in the same folder. While my program is able to access .mat files without any error, xlsx files are not accessible returning the error: Excel couldn't find the specified file. However, when run in matlab environment I do not receive this error. The error appears when I try to run the app from my web server.

Hi Giulio,

have you tried to first build up the full path to the Excel file? So instead of only the file name provide the full path?

Hi Titus, thanks you for your reply. I realize that the problem could be related xlsread function which uses the 'basic' mode when adopted into a web application. Anyway, I'm not sure about that because sometimes it works, other is not

Hi,

you might use the function isdeployed to distinguish:

if isdeployed
    % read from folder A on system where exe runs
else
    % read from folder B on your development system
end
