large csv import and split
显示 更早的评论
What i am trying to do is to import my file (weekly file size around 25GB) to process it. Microsoft excel doesn't open it of course.
How can i import my initial large file into 3 different columns?Thanks in advance!

With a file that's 25GB, you're going to need to break the data up. I recommend using
ds = tabularTextDatastore(filename)
while hasdata(ds)
T = read(ds)
end
You might have to tweak some settings, but this is the easiest way.
