How to modify a txt file

Good morning I have the following info in a .txt file:

*AREA
   26080,   26081,   26082,   26083,   26084,   26085,   26086,   26087,   26088,   26089,
   26090

And I need to read this file and modify it into the next .txt file like this:

*AREA

   26080,
   26081,
   26082,
   26083,
   26084,
   26085,
   26087,
   26088,
   26089,
   26090

How can I do this?

I apprecciate a collaboration

Might be simpler to write a simple c program to do this, and call that c program from within your matlab program.

fidin = fopen('ExistingFile.txt', 'rt');
fidout = fopen('NewFile.txt', 'wt');

header = fgets(fidin);
fwrite(fidout, header);

datacell = textscan(fidin, '%f');
fclose(fidin);

fprintf(fidout, '  %g,\n', datacell{1}(1:end-1));
fprintf(fidout, '  %g\n', datacell{1}(end));

fclose(fidout);
