I create my excel sheet using writetable(T,'Test no21.xlsx') I would like to incrementally increase the number of the excel file to avoid overwriting the previous documents, how can I achieve that?

@Mohamed Sardheye - try using sprintf like
k = 22;
filename = sprintf('Test no%d.xlsx', k);
writetable(T, filename);
Or do you need to determine the 21 from the original file first?

@Mohamed Sardheye - you could use regexpi to match on the integers in your filename. Perhaps something like
filename = 'Test no21.xlsx';
newFileNumber = str2double(filename(regexpi(filename, '[0-9]'))) + 1;
newFilename = sprintf('Test no%d.xlsx', newFileNumber);
