Since all is numeric data, you can use:
data = xlsread('kdd.xlsx');
datanew = unique(data,'rows');

This is not working, because non of data is similar.. I dont find duplicate entries in this sheet provided by Mohammad Alsajri..
using your command, the 'data' and 'datanew' both are getting exact same..

This code works!
I guess the excel provided by Mohammad is just a small portion of the dataset (4 million of rows).
