Every ad platform wants your customer list in a different format. Meta requires SHA-256 hashed emails. TikTok needs E.164 phone numbers. Google wants specific column names. LinkedIn has its own. So you either spend 2 hours reformatting manually in Excel... or pay $200/month for a tool that does it for you. CustomerMatch does it for free. Drop in your CSV → we detect your columns automatically, normalize phones, validate emails, and export ready-to-upload files for all 4 platforms at once.
