read in the .csv file with ddMMyyyy HHmm data

Hello,

I'm trying to read in a csv file which contains datetime data and normal numerical data, which looks like below:

010120180000 0.795

010120180010 0.734

010120180020 0.679

010120180030 0.629

010120180040 0.575

010120180050 0.519

010120180100 0.463

010120180110 0.417

......

the first column represents ddMMyyyyHHmm, and second the column is the water level. I want to read them into a datetime table so that I can easily plot the water level change with time. I tried the following code:

clc;
filename = fullfile('H:\','Filed work','QLD tide info','brisbane_bar_tide_2018.txt');
tidedata = readtable(filename);

but the readtable() function give me a table in which the datetime information been changed to numbers like:

10120180000.0000

10120180010.0000

10120180020.0000

10120180030.0000

10120180040.0000

10120180050.0000

Anyone knows what's the problem? Do I need to convert these numbers to other format?

Thanks!

you can read the file line by line as string https://www.mathworks.com/help/matlab/ref/fgets.html

once it is read then A(1:2) will give you the day and similiarly you can get all other detals . and use string to int conversion to get the integer value https://www.mathworks.com/help/matlab/matlab_prog/converting-from-string-to-numeric.html
