Real estate runs on relationships, and every relationship starts with a contact record. But the contacts an agent collects arrive in a dozen inconsistent formats: open-house sign-in sheets typed into a spreadsheet, portal inquiries forwarded by email, MLS exports, and referral introductions buried in message threads. Turning that scatter into a clean database you can actually farm is tedious manual work.
This workflow shows how to extract every address from those raw sources, separate personal Gmail contacts from business referral partners, and produce a deduplicated list ready to drop into your CRM or newsletter - all in the browser, so client data stays on your machine.
