How to compare different solutions brands and extract specific ones?

Hi to the community,

I'm working on the file "Extraction".

I would like to compare the sheet "Feuil 1" and "Feuil 2". After the comparison, I would like to extract the solutions from the sheet "Feuil 2" that are not established in the sheet "Feuil 1".

In the sheet "Feuil1", the solution's name are located in column A.
In the sheet "Feuil 2", the solution's name are located at the beginning of each sentence, fo example, in the cell G2 "Coupa vs Basware: AP Automation head-to-head technology evaluation and comparison

Thank you a lot for your help and investment for others
