A little guidance.

Remove repeated lines while preserving the original order. You can compare without letter case and trim outer spaces before matching.

How it works

  2. Select “Remove duplicates” to process your input in your browser.

Good to know.

Which copy is kept?

The first matching line is kept. Original order is preserved; the result is not sorted.

Is my input sent to a server?

No. This tool runs in your browser. KILIZU does not upload or store the values or files you enter here.
