T = readtable('zetdctestdata.xlsx');
T.datetime = cellfun(@(x)datenum(x,'mm/dd/yyyy HH:MM:SS'),T.datetime);

and how do i stop matlab from rounding off the outputs in the columns i get 7.3708e+05 instead of 737076.458333333

Actual value in variable is 737076.458333333 but due to format it is rounding off
The default format for command window is Short
T.datetime(1)
ans =
7.3708e+05
Change Format to long
format Long
T.datetime(1)
ans =
7.370764583333334e+05
But it is just for display purpose
