I have a list in Excel more than 3000 rows that I would like to research and replace some words within the list based on another list.

For example:  

List 1:  

Blackcurrant Juice 500ml  

Strawberry Juice 750ml 

List 2:  

have two columns (a: the word that I want to replace, b: the word that I want to replace with)  

A: Blackcurrant should be B: B/currant  

A: Strawberry should be B: Strawb 

And I want search in list 1 and replace the some word based on List two

Any ideas?
