Contact List Cleaner

A tool to remove duplicate contacts from a messy CSV, two ways: an exact-match pass on normalized email/phone (certain duplicates), and a fuzzy pass on names using real string-similarity (Levenshtein edit-distance plus token matching) that catches what Excel's built-in "Remove Duplicates" can't — nicknames, typos, and reordered names. Nothing is ever merged automatically: every group is presented for review, you pick which record to keep, and genuinely different people who happen to have similar names stay separate unless you say otherwise. One-time purchase, works fully offline, never uploads your contact list anywhere.
