orginal='D:\original'
d=dir([orginal '\*.csv']); %Spelling mistake here
files={d.name};
for k=1:numel(files)
   filename=files{k}; 
   fullname = fullfile(orginal,filename );%Getting the fullfile name
   [~,~,b] = xlsread(fullname) ;
   new_name=strrep(fullname,'csv','xls')
   xlswrite(new_name,b);
end

thaks for your help...

i need to write new excels files to master folder in the following path ('D:\master), otherwise old csv files in orginal must be deleted .. i'm using the following code buts also show me an errors ..

orginal='D:\original'
d=dir([orginal '\*.csv']); %Spelling mistake here
files={d.name};
for k=1:numel(files)
filename=files{k};
fullname = fullfile(orginal,filename );%Getting the fullfile name
[~,~,b] = xlsread(fullname) ;
new_name=strrep(fullname,'csv','xlsx')
new_folder='D:\master'
new_file=fullfile(new_folder,new_name)
xlswrite(new_file,b);
end

and its show me the following errors..

Error using xlswrite (line 219)

masterdir = 'D:\master'

xlswrite( fullfile( masterdir, new_name), b)

[Walter Roberson]

[filedir, basename, ext] = fileparts(filename);
new_file = fullfile( masterdir, [basename '.xlsx']);

and you can get rid of some of your other lines like

new_name=strrep(fullname,'csv','xlsx')
