CRM import keeps failing with validation errors you can't decipher
Lead lists from different sources have incompatible formats
Your assistant spends hours manually cleaning data before every import
Why Real Estate Team Leads choose browser-based cleaning
You're importing leads from a real estate conference — 500 contacts with names, emails, phone numbers, and property interests. The spreadsheet has phone numbers in different formats, extra whitespace everywhere, and some duplicate entries. Follow Up Boss rejects the import. You could have an assistant clean it manually, but they'd see all the contact details. CSVCleaner lets you fix it yourself, privately, in minutes.
