How to write time stamp to a specific cell in csv file

I have a csv file that I read and write to it. I need to "stamp" the date and time last accessed.

Couldn't find a simple example.

Assuming I defined,

dt=datestr(now,'mmmm dd,yyyy HH:MM:SS AM'),

I wouldlike to store dt into the csv file on cell F1

Thanks

I believe that is not an option with a csv file. They are text files, so don't have cells or ranges. It may be possible with a spreadsheet. See this example of writing to a specific range of a spreadsheet.

wouldn't dt be a string?

Technically a character array.
