data entry in excel

All of the lists provided have the field in column A as "Name" - the vast majority of the "name" column have both a first name and a last name. I need these splitting out into two columns "first name" (Column A) and "last name" (Column B) - The sheet must also include "Email" (Column C) - Column C is simply the corresponding email address to the first and last name already in the file. So the final sheets must have 3 columns 1. First Name (Column A), 2. Last Name (Column B), 3. Email (Column C). It is very important to make sure you do not mix up the email addresses to different names. For the sheets that I have uploaded that include more columns already, please just make sure that the first three columns include First, Last, Email as instructed, plus all of the other data. Please save the final sheets as CSV files.
