hello everyone
please, I had imported my dataset to run my code, but since then I want to replace this dataset. indeed, when I imported the new dataset, I thought that the old one should be overwritten automatically. when I run the code it is always the old one that appears what to do? thank you for your help
attached my code (untitle5) and my new dataset (mydata)

Try deleting the file before you write it out again.
recycle('on');
delete(fileName); % Send fileName to recycle bin

I think you attached the wrong files. This one doesn't read in any workbook or attempt to write out any workbook.
