I have a similar csv file to the original poster, but when I open it in Gephi 0.81 it doesn't look right. Labels with spaces are split into multiple labels, but after correcting that the real problem is that there is no meaningful network created. Also the 'cell values' (ranging from 0 to 8 in the example below) denote the strength of the connections but they seem to be completely ignored.
What I do get according to the nodes view in the data table is a list of nodes with the correct labels as nodes and id, and under that list the values in the 'cells' treated as labels themselves.
The layout is
dummy;Label 1;Label 2;Label 3;etc
Label 1;0;8;etc
Label 2;3;0;1;etc
etc.
Apart from the use of spaces the format looks identical to the first poster, but it doesn't work. I have removed the spaces which only helped to get the labels correct.
