I trying to compare lists in excel. There are two lists, one list just has one column and the other has two columns, and what I am trying to do is when column A matches column C than take the value in column D and use that to replace column A.

For example:

Column A  Column B Column C Column D
Blue               Blue     Shirt   
Blue               Red      Pants
Red                Green    Shoes
Red
Green
Green
Purple

So the completed list should look like:

Column A  Column B Column C Column D
Shirt              Blue     Shirt   
Shirt              Red      Pants
Pants              Green    Shoes
Pants
Shoes
Shoes
Purple
