Excel Formula Needed

I need assistance with figuring out an Excel formula. I have 2 Excel documents: Document 1 has the employees name, date, and a blank column that I want to fill telling me where they worked that day. Document 2 has the employee name, date, and where they worked that day. How do I match employee name, date, and return the value for where they worked from document 2 to document 1?
Thank you.
