R excels at all of those, and it comes with five manuals one of which is
dedicated to data input/output. How to manipulate data once you have it
loaded is covered in the intro document and many of the other documents
that are available on the web or in a fine library or bookstore near you.

You will find a variety of documents discussing exactly that. You could
start with Frank Harrell's website.
