How can I write any cell data into txt file as they appear.

for example;

data= { 'a' 1 2 3 ; 'b' 4 5 6 }
startingFolder = 'C:\Program Files\MATLAB'

 if ~exist(startingFolder, 'dir')
    startingFolder = pwd
 end
defaultFileName = fullfile(startingFolder, '*.txt')
[baseFileName, folder] = uiputfile(defaultFileName, 'Select a file')
if baseFileName == 0
    return
end

fullFileName = fullfile(folder, baseFileName)
fid = fopen(fullFileName, 'wt')
fwrite(fid, data)  %error using fwrite Cannot write value: unsupported class cell
fclose(fid)

I wanna write numbers as ASCII format with characters. like;

 a    1    2    3

 b    4    5    6

 for j = 1:size(data,1)
  for i = 1:size(data,2)
   if ischar(data{j,i})
     fwrite(fid,[data{j,i} ' '],'char');
   else
     fwrite(fid,[num2str(data{j,i}) ' '],'char');
   end
  end
  fwrite(fid,[10 13],'char')
 end

This: loops through data, and writes each element and a space after every value (change it to ',' for commas or 9 (iirc) for tab spaces; after each row has been written it writes the new line characters (it might be [13 10] or [10 13] I usually need to double check), and then continues. I haven't double--checked the code so there may be an error ro two.

you should follow the link above:

It provides a m-file to write cells to txt
