I would do something like this:
filename = 'hex.csv';
fidi = fopen(filename, 'rt');
D = textscan(fidi, '%*f %*f %*f %s %*s', 'Delimiter',',');
The ‘D’ output will be a cell array of strings.
You may have to experiment to get the result you want. See the textscan documentation for the options the function offers.
