Write 10 excel for loop

Now I have one original.xlsx, I want to write Data in Sheet1 from E1.

xlswrite('Original.xlsx',Data,'Sheet1','E1')

How do I write 10 different Data{#} into Original.xlsx as different excel name, all in Sheet1 from E1.

for i=1:10
  xlswrite('Original.xlsx',Data{i},'Sheet1','E1')?

To confirm, you want to produce just one output file, right? Do you want the ten in different sheets, or do you want them to go into E1 then E2 then E3 and so on? Or do you want the first to start at E1 and then the second to be in E but below where-ever the first finished? Or ...?

I want to have 10 different output excel file. e.g., first one save as 'January.xlsx', second on save as 'February.xlsx', ... All go into E1. Thank you in advance.

filenames = {'January.xlsx', 'February.xlsx', 'Cheezburger.xlsx', 'Durango95.xlsx', 'EschewObfuscation.xlsx', ....};

for i=1:10
  xlswrite(filenames{i}, Data{i}, 'Sheet1','E1');
end

For those 10 filenames, e.g. 'January.xlsx', before we add Data{i}, it should contain the same information from Original.xlsx. How do we rewrite the code you wrote.

Thank you a lot.

I am not sure what you mean; perhaps you mean something like,

filenames = {'January.xlsx', 'February.xlsx', 'Cheezburger.xlsx', 'Durango95.xlsx', 'EschewObfuscation.xlsx', ....};

[~, ~, orig_raw] = xlsread('Original.xlsx', 'Sheet1');

for i=1:10
  xlswrite(filenames{i}, orig_raw, 'Sheet1');
  xlswrite(filenames{i}, Data{i}, 'Sheet1','E1');
end

However if you were going to do that then I would use

filenames = {'January.xlsx', 'February.xlsx', 'Cheezburger.xlsx', 'Durango95.xlsx', 'EschewObfuscation.xlsx', ....};

[~, ~, orig_raw] = xlsread('Original.xlsx', 'Sheet1');

for i=1:10
  outdata = orig_raw;
  new_data = Data{i};
  outdata(1:length(new_data),5) = new_data;
  xlswrite(filenames{i}, outdata, 'Sheet1');
end

Note: if Data{i} a numeric vector then you would use

for i=1:10
  outdata = orig_raw;
  new_data = num2cell(Data{i});
  outdata(1:length(new_data),5) = new_data;
  xlswrite(filenames{i}, outdata, 'Sheet1');
end

But if Data{i} is a numeric scalar or string then you would use

for i=1:10
  outdata = orig_raw;
  new_data = Data{i};
  outdata{1,5} = new_data;
  xlswrite(filenames{i}, outdata, 'Sheet1');
end

I think you answered my questions. I will check the code after I finished the Friday party. Thank you in advance

You can write the whole cell array at once. See the cell array example in the online help: http://www.mathworks.com/help/releases/R2015b/matlab/ref/xlswrite.html

If you are asking about the for loop because you first are calculating each cell before writing, I'd advise to export to Excel in a separate step after the loop for performance reasons.
