Hello, I have been given a task to evaluate a questionnaire. It is a questionnaire with irrelevant questions and timestamps and answers, most are numbers, a few are also text. I do not understand the following subtask:
"Bring it in a usable form (some answers are numbers, others are text)".
What could be meant by this?
Here is an excerpt from the data: (The Data is already as a table in Matlab)
Looking very much forward to your answers! Thanks in advance!

To be able to guess, what "usable" means, we need to know, what do you want to use the data for. Maybe you should convert the time stamp to a datetime object. If the 3rd column is easier to use, when it is converted to a string or if a double value is better, depends on what you want to achieve.
So this is actually not a Matlab question, but you have to decide at first, what you want to do.

Thank you for your Answer!
I simply want to visualize the date, nothing special, just some interesting plots. The Timestamp is already a datetime object. Here you can see how it looks like in Matlab:
