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?
