Compare sheet with salesforce outpout

Hello everyone,

In my current workflow I recover all my salesforce leads as well as the data from a google sheet.

I want to check if the emails in my leads are in my sheet (check each address extracted from salesforce and identify which ones are already in my sheet and which ones are not yet.) in order to add the news in my sheet.

Do you have any idea how to make it as simple as possible in n8n?

Thank you in advance, have a good day!

You can use the merge node for that. Check the example below.

Thank you Ricardo !
