Question

I have a really huge CSV files. There are about 1700 columns and 40000 rows like below:

x,y,z,x1,x2,x3,x4,x5,x6,x7,x8,x9,...(about 1700 more)...,x1700
0,0,0,         


        

Answer 1

I usually use open office ( or microsof excel in case you are using windows) to do that without writing any program and change the file and save it. Following are two useful links showing how to do that.
