Hey guys,
I was wondering if there was a way I could ask a user if their file is .csv, and if not, I would sent it through a loop to have it converted to .csv. Is there any way I could do that?
Thanks!

Why not assume the extension is correct and process it if necessary?
[folder, baseFileName, extension] = fileparts(filename);
if strcmpi(extension, '.xlsx')
numbers = xlsread(filename);
csvFileName = strrep(filename, '.xlsx', '.csv');
csvFileName = strrep(csvFileName, '.xls', '.csv');
csvwrite(csvFileName, numbers);
end

But it writes only numbers not including row and colomn headers. How these can be included in the .csv file?

You can use fprintf() to write it out exactly as you want.

clear; clear all; fileip='filename.csv'; g=char(fileip); g=g(1:end-4) fileop=horzcat(g,'.xlsx') g=fileip(1:end-4); [~,~,F]=xlsread(fileip); F=cellstr(F); %delete the header rows (4 rows) F([1:4],:)=[]; for a=1:size(F,1); b=F(a,1); c=char(b); D(a,:)=strsplit(c,','); end xlswrite(fileop,D); disp(['--------------Process complete---------------------']);

file = dir('*.xlsx'); % make sure your are navigated to the right folder on matlab
s= size(file,1);
for i= 1:s
Data = xlsread(file(i).name);
filename=file(i).name;
filename= filename(1:end-5); % to remove extension from filename
csvwrite([filename '.csv'], Data);
end
