How save data from cell to array?

Hi everyone, I want to save centroid value as an array (excel sheet format). but, I am getting [x,y] in a single cell. I don't know how to convert it.

My code

    for i=1:files
        file = imagefiles(i).name;
        I = imread(file);
        BW = im2bw(I,0.6);
        BW3 = imcomplement(BW);
        BW4 = imfill(BW3,'holes');
        BW6 = imcomplement(BW4);
        C{i} = regionprops(BW6,'centroid');
    end

Output:

 {}C 158*1 cell  /workspace
 [2.51,4.82]     /in each cell both value separated comma
