Thank you, sir

but time is showing in decimal, how to correct into normal?

I want to use the function fopen and textscan.

fmt = ['%{dd-MMM-yy}D%{HH:mm}D', repmat('%f', 1, 50)];
fbc = fopen('ABCD.CSV', 'r', 'n', 'UTF8');
BC = textscan(fbc, fmt, 'Delimiter', ',', 'CollectOutput', 1);
dt = BC{1}+(BC{2}-dateshift(BC{2},'start','day'));
dt.Format = 'default';
numbers = BC{3};
