csvexport(filename,​cellVals)

Simple command to convert a cell array into a CSV file, easily accessible to matlab. No extensions, no java, no fuss. Purely fopen, fwrite, fclose. Pretty basic, does not position the array into a specific location/range. Obviously no sheet option because it is not an excel file. I will be happy to add range functionality if there is a strong demand, but it is relatively straight-forward to read and append file (see csvimport.m)
