outfile = 'mydata.xlsx';
dinfo = dir('*.xlsx');
filenames = setdiff({dinfo.name}, outfile);
for K = 1 : length(filenames)
thisfile = filenames{K};
[~, basename, ~] = fileparts(thisfile);
T = readtable(thisfile);
writetable(T, outfile, 'sheet', basename);
end

The code runs and my mydata.xlsx with sheetname was created but the data from T were not written in any of the sheet. All the created sheets were blank. kindly help.

Thank you this code worked very well but the outfile mydata.xlsx is difficult to open in excel. l guess it is because we use readtable and writetable. Can we use xlsread and xlswrite instead? I have it brought out error message. Kindly help.

That seems unlikely to be the reason, but you can try xlsread() / xlswrite() anyhow.
outfile = 'mydata.xlsx';
dinfo = dir('*.xlsx');
filenames = setdiff({dinfo.name}, outfile);
for K = 1 : length(filenames)
thisfile = filenames{K};
[~, basename, ~] = fileparts(thisfile);
[~, ~, raw] = xlsread(thisfile);
xlswrite(outfile, raw, basename);
end
