Clean a list by removing repeated lines, keeping only the first occurrence of each — with an option to ignore case and surrounding spaces.
How it works
- Paste your list of items into the text area.
- The tool scans line by line, preserving the first instance and deleting the rest.
- Copy your deduped list.
Frequently asked questions
Does it keep the original order?
Yes — the first occurrence of each line stays in place; later duplicates are removed.
Does it ignore leading spaces?
Lines are trimmed before comparison, so indentation differences do not block duplicate detection.
What about case?
Switch on "ignore case" to treat differently-cased lines as duplicates.
