MATLAB: How to import an excel file and split a column

import excel columns

Hello guys! I hope everyone is health and safe…
I would like to ask a question please:
I am trying to import some excel files like the one I have attached, with Import option of Matlab R2019a. I want the first column, which contains date ant time together, ti be imported as two separate columns, one with date and one with time.
Is there a way to do it using Import?
Thank you in advance!

The short answer is no. Your timestamps are stored in the spreadsheet as floating point numbers. But why do you need to split time and date during import?
Read in the data using readtable, then use the timeofday function on the datetime variable in your table to make a new time variable i nthe table, then subtract that from the date.
>> t = table(datetime(2020,19,1) + 5*days(rand(5,1)),rand(5,1))
t =
  5×2 table
            Var1             Var2

>> t.Date = t.Var1 - t.Time;
>> t.Var1 = []
t =
  5×3 table
     Var2        Time         Date
