Remove Duplicate Rows

Remove repeated rows from a CSV, comparing all or selected columns.

Everything is processed inside this browser tab. Pixuna does not upload your text or files to a server.

How to use Remove Duplicate Rows

  1. Paste CSV into the box, or choose Open a file to load a .csv, .tsv, or .txt file.
  2. Leave the delimiter on automatic detection, or pick it yourself, and set whether the first row is a header.
  3. Optionally list the columns to compare, and choose which occurrence to keep.

What to know

Only exact matches (after your trim and case settings) are treated as duplicates.

The result shows how many rows were removed.

File handling: This tool runs in your browser. Your text or file is processed in the tab on your device, and Pixuna's code does not upload it to a server. You can confirm this in your browser's network panel.
