hello Rachele
you can do this -
I used natsortfile (from FEX : https://fr.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort ) to make sure the data are grabbed from the files in their natural name sorting which is not what matlab does autmatically
clc
clearvars
fileDir = pwd;
outfile = 'OUT.xlsx'; % output file name
fileNames = dir(fullfile(fileDir,'data*.xlsx')); % get list of data files in directory
fileNames_sorted = natsortfiles({fileNames.name}); % sort file names into order (https://fr.mathworks.com/matlabcentral/fileexchange/47434-natural-order-filename-sort)
M= length (fileNames_sorted);
out_data = [];
for f = 1:M
% option # 1 for numeric data only using importdata
raw = importdata( fullfile(fileDir, fileNames_sorted{f}));
% vertical contatenation of all individual files data
out_data = [out_data; raw.data];
end
% store out_data in excel file
writematrix(out_data,fullfile(fileDir,outfile));
