Delete duplicate rows in a few clicks

Upload an Excel or CSV file, choose whether to match entire rows or only selected columns (such as email or customer ID), and decide whether to keep the first or last occurrence. Options to ignore case and trim spaces catch near-duplicates that Excel’s built-in tool misses.

Download the cleaned sheet as XLSX or CSV. Processing stays in your browser, so customer lists and contact data are never uploaded.
