Cell Splitting based on special character

Summary

Split a field into two columns based on character

Content

Suppose I have a field (Name) in Last Name, First Name format. 

I want to make this into two columns instead that is Last Name and First Name by splitting the field based on the comma. Is this possible in OTBI and how would I accomplish this? 

I want to do this for the hiring manager and recruiter fields in Taleo BI but first name and last name aren't applicable choices for this so I'm trying to use a formula instead.
