How can I change the current folder to folder of .m file in my code.
Possibly with cd command
Or any command I can indicate that my excel file is in same location as .m file.
e.g. code.m path folder\My excel file.xls

Here's some code I got from Brett Shoelson of the Mathworks:
% Change the current folder to the folder of this m-file.
if(~isdeployed)
cd(fileparts(which(mfilename)));
end
Edit: Note that the isdeployed is important if you will be compiling and deploying your application. This let's it operate both for you, as the developer, and for your deployed application where it will skip the cd because doing cd like that in a deployed app can wreak havoc. If you won't be doing compiling, then you can do just the cd without the if.

If I have a live script on the MATLAB online drive inside some subfolder, what should I write to change the working directory to that of the live script since
cd(fileparts(which(mfilename)))
doesn't work for live scripts on the online drive?
My workaround is to copy/paste your code inside an m-file in the same subfolder and call it at the very first line of my live script, however, I would like to have a neat solution.

mfile_name = mfilename('fullpath');
[pathstr,name,ext] = fileparts(mfile_name);
cd(pathstr);

For live scripts, @Qi Wang suggested using this:
fileparts(matlab.desktop.editor.getActiveFilename)
to get the full path of the active live script file.

cd(which(fileparts('/path/to/your/file.m')))
