CSV Duplicate Remover
Find and remove duplicate rows from a CSV file. Choose the columns that define a match, review the result, and download a clean copy.
Clean your CSV
Paste CSV text or choose a .csv file. Your data is processed on this device and is never uploaded.
The first matching row is kept. Fully blank rows are omitted from the cleaned download. Keep a copy of your original file if you need it later.
About this CSV duplicate remover
How are duplicates detected?
By default, every column must match. After loading data, uncheck columns to compare only the fields that identify a record, such as an email address or product ID. The first matching row stays in the clean file.
Does this tool upload my file?
No. CSV parsing, duplicate checks, preview, and export run locally in your browser. The selected file contents are not sent to EasyTility.
Which files are supported?
Comma-separated CSV files, tab-separated text, and semicolon-separated files are supported. The output is downloaded as UTF-8 CSV.
