CSV Deduplicator
Upload a CSV, pick the column(s) that identify a row, and download the cleaned file with duplicates removed. Runs entirely in your browser — your file never hits our servers.
Your file never leaves your browser. Processing is local only.
This tool finds exact duplicates only.
If your duplicates have typos, formatting differences, or nickname variations — "John Smith" vs "J. Smith", "Bob Jones" vs "Robert Jones", phone numbers formatted differently — you need fuzzy matching. That's what the full ListMatchGenie product does, alongside AI-powered reports and review queues.
