read the file as a single string using fileread(). Use regexp() with named tokens to extract the desired information. Create a cell array from the resulting structure array. xlswrite() the cell array.

So you just gave up? What about trying fgets() or fgetl(), textscan() etc. or any of the other functions listed at the bottom of the help for fileread() in the "See also" section? Then you might use strfind(), sscanf(), etc. Keep working at it.
