saving in a specific text file format

Dear Matlab users

I am preparing a text file. I have an excel file (A.xlsx) with two columns.

25.000    10.000
26.000    9.000
.........     ..........

I want to save a text file with the following format(first number,second number with three decimal).

25.000,10.000
26.000,9.000

I tried the code like this. But, the output result comes out with zigzag and not a separated files. So, how can I save the data and please help me. Thank you very much.

clear all;clc

A= xlsread('A.xlsx');
A1=A(:,1);
A2=A(:,2);
fileID = fopen('output.txt','w');
fprintf(fileID,'%2.3f,%2.3f\n',A1,A2);
fclose(fileID);

>> fmt='%8.3f,%8.3f\n'
fmt =
    '%8.3f,%8.3f\n'
>> fprintf(fmt,A.')
  25.000,  10.000
  26.000,   9.000
>>

hello sir

how can i remove space after comma because I don't need it in my file.

If you do not have the fixed width then your output will appear zigzag which you do not want.

dear walter thank you for your comments.

You can minimize the number of blanks by setting the width of the field to the minimum needed for the largest value in the array but you can't eliminate entirely unless all values are within the same order of magnitude (hence have same number of digits).
