I am running a user input function, where the user enters multiple codes in a text box. Each code has the form "04 11 70 32 24 6d 80", and the clock generates a date and time of this action. Everytime the user inputs the codes, they are made into a cell array named 'x' in the workspace (along with the clock data, named 'c'). How can I save each version of the codes cell array and clock into a table everytime they change?

Hello Aliki,
It is my understanding that you want to convert workspace variables into a table.
You may refer the following links for doing so:

Since you are working with timestamped data it would be better to use timetables instead of tables. With timetable you can simply start with an empty timetable, and then use tt.Var(idx) syntax to keep adding values as shown below
>> tt = timetable
tt =
0×0 empty timetable
>> x = {"aa bb cc"}
x =
1×1 cell array
{["aa bb cc"]}
>> c = datetime
c =
05-Apr-2022 16:10:08
>> tt.Codes(c) = x
tt =
Time Codes
____________________ ______________
05-Apr-2022 16:10:08 {["aa bb cc"]}
>> x = {"aa1 bb2 cc3"};
>> c = datetime;
>> tt.Codes(c) = x
tt =
2×1 timetable
Time Codes
____________________ _________________
05-Apr-2022 16:10:08 {["aa bb cc" ]}
05-Apr-2022 16:10:21 {["aa1 bb2 cc3"]}
