Hello all,
I have an excel file with 4 sheets: A, B, C, D and each sheet has it own data, i'd like to mix all data in just one sheet and write the value in front of each sheet's name, for example see the photo: thanks

@Abo, well, inside your loop you don't specify the sheet to read from, so it's always reading from the first one.
@Karen, according to the example, each sheet would only have one row of data but a different number of columns. As tables, you wouldn't be able to concatenate them.

for i = 1:numel(sheets)
T{i} = xlsread('Result.xlsx', sheets{i});
end
Now each T{i} is the data from one sheet, with sheet name sheets{i} . You can manipulate this to get a common format. The best way to do that is going to depend on what your input sheets look like.
You would be wanting to figure out the widest that you need, and create a cell array that wide, in which the cells started out empty. Then fill rows of that with as much data as exists for one sheet, leaving the extra columns empty. The end result would be a cell array you could xlswrite()

files=dir('*.xlsx');
[~, sheets] = xlsfinfo('Result.xlsx');
sheetcontent = cellfun(@(sh) xlsread('Result.xlsx', sh), sheets, 'UniformOutput', false); %collect content of each sheet
%before concatenating the contents into one cell array, it needs to be the same size for all sheet
maxcols = max(cellfun(@numel, sheetcontent)); %maximum number of columns
sheetcontent = cellfun(@(c) [num2cell(c), cell(1, maxcols-numel(c))], sheetcontent, 'UniformOutput', false); %append empty cells
sheetcontent = vertcat(sheetcontent{:}); %and concatenate
xlswrite('Mergedresult.xlsx', [sheets(:), sheetcontent]);

I made a mistake in the code that appends empty cells (to make the content of each sheet the same width). Fixed now.
Note that the above code assumes that xlsread only read ONE row per sheet.
