converting date and time string to datetime object

I am trying to read several text files each has 4 variables, the first coumn has the date and time values otgether in the following format

''2022-02-16T15:50:00.000Z'', and I would like to convert them in the following format "20220216155000".

I would like to convert theis into a datetmir object so i can use these vaues to compare to other dates and times from a different tables.

I am using the following lines for converion

 for x = 1:length(Ionotable.x_Time)   %x_Time is the column where the date and tie values are stored
    Ionotable(x,1) = datetime(string(x),'InputFormat','yyMMddHHmmss'); 
   end

but I am getting the follwoing error

   Error using datetime (line 651)
Unable to convert '1' to datetime using the format 'yyMMddHHmmss'.

Error in Ionosonde_Data (line 23)
    Ionotable(x,1) = datetime(string(x),'InputFormat','yyMMddHHmmss');

k = 1; 
while k<=length(Ionotable.x_Time)
     x = (Ionotable.x_Time(k))   %x_Time is the column where the date and tie values are stored
    Ionotable(k,1) = datetime(string(x),'InputFormat','yyMMddHHmmss'); 
    k = k+1;
end

Thank you for replying to my question,

Error using datetime (line 651)
Unable to convert '2022-01-01T00:00:00.000Z' to datetime using the format 'yyyyMMddHHmmss'.

Ionotable(k,1) = datetime(string(x),'InputFormat','uuuu-MM-dd''T''HH:mmXXX','TimeZone','UTC'); 

use a different input format

[VBBV]

Ionotable(k,1) = datetime(string(x),'InputFormat','uuuu-MM-dd''T''HH:mmXXX','TimeZone','UTC'); 
Itable(k,1) = datetime(string(Ionotable(k,1)),'InputFormat','yyMMddHHmmss') % 

2 step conversion may be needed
