Is D a local disk or a remote network disk? This will go much faster if you save the files locally before trying to read them all.
fileDir = 'D:\excel_folder';
outfile = 'D:\MASTER.xls';
fileNames = dir(fileDir);
fileNames = {};
fileNames = fileNames(cellfun(...
for f = 1:numel(fileNames),
fTable = readtable(fileNames{f});
Each sheet of MASTER.xls should now have the same name as the file that contained the data.
Hope this helps.

Hi @Walter. I want to ask about how to merge multiple xls files into a single file with the same worksheet. I read some questions which also have the same problem, but mostly the resulted file has separate worksheets. In my case, I want to merge the table so that it only has one worksheet. I try this code below:
[files,folder] = uigetfile('*.xls','Select Files','MultiSelect','on');
output = fullfile(folder,'rainfall.xls');
for i = 1:numel(files)
ftab = readtable(files{i});
but of course it has separated worksheets. I want to make it in one worksheet as the files have also the same structure so it should be easily to merge. Do you know what should I modify in my code above? I really appreciate for your help.

I have two quetions:
1)I am getting an error that fileNames is undefined, what is the best course of action? 2)could someone possibly explain the "cellfun(..." part of the code?
Thank you!
