I am trying to convert the first column to a character string, so I can split the character string values to create a Date/Time format to sort data later on. When I try to isolate the column in Matlab, it skips the first column and uses only the second column. Can anyone help me isloate the first column?
This is what I have tried so far
T = xlsread('Vibes.xlsx');
C = str2double(T(:,1));
T = xlsread('Vibes.xlsx');
C = T(:,1);

If you use the Import Data tool (in the Variable section on the Home tab of the toolstrip) you can import the data directly as a datetime array. Just specify the format. If you have multiple of these files in the same format to import, you could even create a script or function to automate the import process for the second and later files (and to see the code MATLAB used to import the data so you can learn from it.)

They underscore can be included in the input format.
date = '2020-09-11_04:11:50.648000';
datetime(date,"InputFormat",'yyyy-MM-dd_hh:mm:ss.SSSS')
