a = dir('d:\mytimsarehere\*.tim');
for i = 1:numel(a)
filename_in = ['d:\mytimsarehere\' a(i).name];
filename_out = [filename_in(1:end-3) 'txt'];
fid = fopen(filename_in,'r');
ascii = fread(bin, [43,21000], 'float32');
data_values=ascii';
dlmwrite(filename_out, data_values, 'delimiter', '\t', ...
'precision', '%.6f','newline','pc');
fclose(fid);
end

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']);
...

Use uigetfile to read multiple file names in a loop.
for example...
for i=1:500
[filename, pathname, filterindex] = uigetfile('*.tim', 'r');
end
