As others stated above it would be wise to  stick with SEED only unless you have a specific reason to need those private keys.  Is there a reason that you decided to export all those private keys?  Its OK if you just did a newbie thing, we were all there once.  I cannot stress enough how important it is to make sure that those private keys and SEED never get in someone else's hands.  It would be a disaster for your coins staying in your wallet.
