CSV Deduplicator
Remove duplicate rows from a CSV before importing into your CRM. Pick the columns that define a duplicate — email, phone, name — and download a clean file. Your data never leaves your browser.
Matching: key values are normalized (trimmed, lowercased, whitespace-collapsed) before comparison, so John@Example.com and john@example.com count as duplicates. Select multiple columns for stricter matching — e.g. first name + last name + email.
