I don't think you want to save them in a text file or an Excel workbook, based on reading your other posting. I think they should be images also. Use something like this (untested)
[labeledImage numberOfBlobs] = bwlabel(binaryImage, 8); % Label each blob so we can make measurements of it
% Get all the blob properties.
blobMeasurements = regionprops(labeledImage, 'PixelList');
for r = 1 : numberOfBlobs
% Extract blobs one at a time.
% Note how we use ismember() to do this.
oneRegion = ismember(labeledImage, r);
% Save it to disk.
baseFilename = sprintf('Region number %d.png', r);
fullFileName = fullfile(folder, baseFilename);
imwrite(oneRegion , fullFileName);
thesePixels = blobMeasurements(r).PixelList;
% Now use fopen(), fprintf(), and fclose() to write thesePixels to a disk file.
end

Sorry - I edited it to fix the mistake. I assume you know how (or can easily figure out how) to use fprintf() to write the coordinates to a file. Comment out the filename and imwrite line if you don't want an image file. Don't use Excel since that will take a long time - much longer than fprintf().
