Looping is the way to go. Depending on the dimensions of your cell you need to modify this, but for an example cell array named X with 2 cells, the first a 1x4 and the next a 1x7;
for i=1:size(X,2)
range=strcat('A',num2str(i),':A',num2str(i)); %write from excel cell A1 on the first run, A2 next run etc.
xlswrite(X{i,1},)
end
If some cells in your cell array are 2D, you will need to adjust accordingly. Note for this specific example your cells need to be rows - if they are columns, simply put a ' next to it.
