A free Google Apps Script that pulls every email address (and name, when available) from your Gmail into a Google Sheet you can download as a contact list. De-duplicates, filters automated noise, resumes past the Apps Script time limit, and runs entirely inside your own Google account (read-only, no external calls). See its how-to guide.
