problem with xlswrite function

how to write individual characters to string in a single cell (when the string is divided to individual characters in to the cells in xlswrite) . When executing the following code the date,day are seperated in to cells (dt = datestr(now,'mmmm dd, yyyy HH:MM');). Could any one plesae help me whether can i write entire date in single cell and day in another single cell..And is there any chance of writting a string in A cell while executing this code......(this code is about student attendance system updated in excel sheet)

function notout=Record_attendance()

xlswrite('att1.xlsx',{dt},'Sheet1',se);

[Kalyan Seelam]

this was worked fine but still there is a problem with that as shown

[Kalyan Seelam]

Only D cell (In january 'J' was replaced with Datetime),but remaining letters were still appearing...and one more is that can i add name(string) to the first cell ...

Thank you

[Walter Roberson]

Did you delete the old att1.xlsx before you made the change to xlswrite {dt} ?

[Kalyan Seelam]

No,but after deleting its working fine.

There is problem with writing name(string)in A cell can you please clarify it...

Thank you

[Walter Roberson]

What is your current code?
