I have a csv file that loads very perfectly from 2nd column onwards.
data = csvread('filename.csv',1,1);
However, in the first column of my data I have date:
the format of the date is
2012/09/15 00:00:00,0,-13.654,...
2012/09/15 00:00:01,0,-18.654,...
2012/09/15 00:00:02,0,-166.654,...
2012/09/15 00:00:03,0,-178.654,...
...
...
...
Here, date is space separated with time. This creates error in loading the file using
data = csvread('filename.csv',1,0);
Can anyone suggest what to do?

What happens when you use
readtable()
because they are capable of reading dates by default

filename.csv should be the name of your csv file

Hey, thank you for your efforts. But, please note that the data file is not text file. It is csv file.
So readtable asks for text format.
When I tried with text file, It works well like you have shown in above example
Hey, Thank you very much for your time and efforts.
I found the solution.
opts = detectImportOptions('filename.csv');
T = readtable('filename.csv',opts);
Thanks!

Csv files are defined as text files. If you were to rename that sample.txt to sample.csv it would be able to read it.

@Megha exactly as sir Walter mentions if you change .txt to .csv it would read the file without any flaw!
