How can I select numbers from excel to matlab?

Hi, I have an excel file with only 1 column and every cell results as follows:

'2019-10-12T02:41:27.091Z,1/0669958925:52238,-5.9858581261e-02,-1.7725070822e-04,+1.1940838453e-03'

In order to pass from excel to matlab i wrote the following:

[num,str]=xlsread('file1');

num is empty, str is a Nx1 cell. Each cell is a char like the following I wrote before.

How can I extrapolate the last 3 numbers and the date at the beginning of this char? Thank you for the help!

Attach your file.

Sorry David but I can't attach the file, It's an excel file with only a coloumn and every cell is formed as follows:

2019-10-12T02:41:27.091Z,1/0669958925:52238,-5.9858581261e-02,-1.7725070822e-04,+1.1940838453e-03

str=readcell('test.xlsx');
%str={'2019-10-12T02:41:27.091Z,1/0669958925:52238,-5.9858581261e-02,-1.7725070822e-04,+1.1940838453e-03'}
for k=1:length(str)
  T(1,:)=[regexp(str{k},'\d{4}[-]\d{2}[-]\d{2}','match'),regexp(str{k},'[+-]\d+[.]\d+[e][-]\d+','match')];
end
