About the Duplicate Line Remover

Paste a list — emails, keywords, product codes, anything one per line — and every repeat is removed, keeping the first copy in its original position. Choose whether “Apple” and “apple ” count as the same line.

How to use it

  1. 1Paste your list, one item per line.
  2. 2Choose whether to ignore capitals and surrounding spaces.
  3. 3Copy the unique lines, or the duplicates that were removed.

Questions

Does it change the order of my list?

No. The first time a line appears it stays where it was; later copies are removed. Use the Text Formatter afterwards if you want the list sorted.

Is my text uploaded or stored?

No. The tool runs in this browser tab. What you paste is never sent to KuponGuru, and it is gone when you close the tab.
