Hi,
You need to do a loop like this :
for i = 1:n
% ask the user the name of excel file (without the extension)
XlsFile = input('Enter the Excel file name : ','s');
% Read the spredsheet by adding the _.xlsx_ string to the Xls filename
XlsData = xlsread([XlsFile '.xlsx']);
% then : code to process XlsData
end
You might consider to remove the input of the for loop and define your xls files before, otherwise the user has to be ready to write at each iteration, which can take a long time.
