Can I import data back into a Qualtrics survey? Odd request I know

This is a little odd -
So I sent an email that passed (via the HTML in the email - &email=[email] etc) both email and model name into a Qualtrics. The problem is that the data file that I uploaded into my ESP to send the email was messed up and the model names did not pass.

So the question is can I export the data from qualtrics, fix it in excel by appending the proper models to their email addresses, and then import it back into qualtrics so that the client can analyze the data and assemble charts in Qualtrics?

Thanks everyone
