I have a gui that performs an xlswrite function and creates a file called summary.xlsx in a folder. When I turn this into an executable I want the current directory of that executable to replace that filepath in xlswrite. What does this code look like?

For Windows, the attached function works to find the "real" folder where the executable is, which is not where mfilename says it is.

Would the xlswrite code ultimately look like:
% Returns the folder where the compiled executable actually resides.
function [executableFolder] = GetExecutableFolder()
try
if isdeployed
% User is running an executable in standalone mode.
[status, result] = system('set PATH');
executableFolder = char(regexpi(result, 'Path=(.*?);', 'tokens', 'once'));
% fprintf(1, '\nIn function GetExecutableFolder(), currentWorkingDirectory = %s\n', executableFolder);
else
% User is running an m-file from the MATLAB integrated development environment (regular MATLAB).
executableFolder = pwd;
filename=[pwd,'Summary.xlsx']
end
catch ME
errorMessage = sprintf('Error in function %s() at line %d.\n\nError Message:\n%s', ...
ME.stack(1).name, ME.stack(1).line, ME.message);
uiwait(warndlg(errorMessage));
end
return;
%Later in my code
xlswrite(filename,DataSummary,1,'A2')

No. You'd do something like
executableFolder] = GetExecutableFolder();
%Later in my code
fullFileName = fullfile(executableFolder, 'DataSummary.xlsx');
xlswrite(fullFileName , DataSummary,1,'A2')
