  filename_out = [filename_in(1:end-3) 'txt'];
  fid = fopen(filename_in,'r');

The OP wants 'xls'. "1:end-3" removes the dot also. More flexible:

folder = 'd:\mytimsarehere\'; 
a = dir(fullfile(folder, *.tim'));
for i = 1:numel(a)
  filename_in  = fullfile(folder, a(i).name);
  [dummy, name] = fileparts(a(i).name);
  filename_out = fullfile(folder, [name, '.xls']);
  ...
