Combine excel database

Hi excel experts, due to some internal issue i need to combine page 1 and page 2 of this excel by checking product name. if product name is the same then copy sheet2 from colomn L onwards to sheet1 to the correct product / row so i will have a combined historical sales. I will need documentation on how to do this as i have a few files that i need to fix

Nb: product name in excel is not real product name
