So my Data i want to show is date, time, left or right side and name.
Thanks for any help!
% Button pushed function: EinlesenButton
function EinlesenButtonPushed(app, event)
%Diese Funktion dient dem direkten Lesen der auf dem übergeben Pfad
%hinterlegten CSV-Datei. Diese Datei muss exakt der Formatierung der
%Dateien entsprechen die das Program "Power" des Diagnostikgerätes
%liefert.
%Einlesen der Datei über den Umweg mit strings
% Öffnen eines Fensters zur Auswahl der zu öffnenden .csv Dateien.
[filename,pathname] = uigetfile('*.csv;','MultiSelect',"on");
for i = 1:length(filename)
filepath=fullfile(pathname, filename);
fid = fopen (filepath{i});
%[file,path]=uigetfile('*.csv');
A = textscan(fid, '%s%s%s%s%s%s%s%s%s%s%s%s%s','Delimiter',';');
%Umwandeln von Cell --> String
B=string([A{:}]);
%',' durch '.' ersetzen
B=replace(B,',', '.'); % ',' durch '.' ersetzen
% Aufteilen in Header und Messdaten
Daten(i).Header=B(1:30,:);
Daten(i).Messdaten=str2double(B(31:end,7));
end
for i = 1:length(filename)
%Uhrzeit
x = char(Daten(i).Header(12,1));
x1 = extractBetween(x,13,20 );
%Datum
y = char(Daten(i).Header(11,1));
y1 = extractBetween(y,11,20);
%Bein Seite
z = char(Daten(i).Header(21,1));
if strlength(z) == 22
z1 = extractBetween(z,10,14);
else
z1 = extractBetween(z,10,15);
end
app.UITable.Data(i,2) = cell2mat(x1); % <------ Here starts my problem
app.UITable.Data(i,3) = cell2mat(y1);
app.UITable.Data(i,4) = cell2mat(z1);
end

Based on those data, I'd use readtable. That function allows you to define the row where the tabular data start and it also allows you to define the input format of datetime values With 1 line of code you could read in the data with the correct datetime values.
