Hello, I'm trying to open certain excel file with xlsread and add user inputs to that file using xlswrite. But when I open excel file after adding new data, I cannot find original data but added ones. Can anybody help me with this?

close all;
clear all;
clc;
[num,txt]=xlsread('filename.xlsx'); %I have both num&txt data, including header
nn=length(txt);
n=nn+1;
A={};
while(1)
    m=input('');
    if m==1
        fprintf('---------------------------\n')
        number=input('- Sentence       :','s'); %here I'll get number and text data
        Anew={number(1:3),number(4),number(5:8)};
        A(n,1)=(Anew(1,1)); %num
        A(n,2)=(Anew(1,2)); %txt
        A(n,3)=(Anew(1,3)); %num
        n=n+1;
    end
    if m==0
        xlswrite([num,txt],A); %actually I'm not sure what to write here :(
        break;
    end
end
