Exporting multiple iterations of inputdlg user input into excel file

I am going to include my whole code because I don't know where I went wrong. You can see on line 63 where I tried to use a for-loop to save multiple rows of user inputs as they are used, however the final exported excel file just has whichever the last input was. I have tried to use counters, but variable UserInput is considered a "double" and not a "cell" so I can't do that either. Let me know if you have any thoughts and thank you so much.

function user_input(hObject,varargin)
%This function runs a program which allows the user to input addresses into
%a spreadsheet which is saved in an excel file.
%The function uses input and question dialogue boxes, allows the user to
%correct mistakes through a GUI, and has a refresh button which allows the
%user to see the corrected information.

input_prompt={'First name:','Last name:', 'Address:','City:','State:','Zipcode:'}; % a list of input prompts which will be used
dlg_title = 'User Input'; %The title for the dialogue box
num_lines = 1; %The number of lines required for input
default_ans= {'Jane','Doe','100 Example St.','Exampletown','NJ','11567'}; %default answers for the dialogue box
options.Resize='on'; %allows the user to resize the window if necessary

UserInput=inputdlg(input_prompt,dlg_title,num_lines,default_ans,options); %initiates dialogue box and saves the answers in a column
UserInput= UserInput'; %changes the columns to rows

You're really close! Try this as an example:

N = 3;
loopData = cell(N,1);
for ii = 1:N    
    userDlg = inputdlg('Hit any key',sprintf('Dialogue (loop %i/%i)',ii,numel(N)),[1,50]);
    loopData{ii,1} = userDlg{:};    
end

xlswrite('NewData.xlsx',loopData)
