How to use
Paste a list — one item per line — and choose an action. Copy the result back into a spreadsheet, a document or your code.
What you can do
- Remove duplicates — keeps the first occurrence of each line and the original order.
- Duplicates, ignore case — “London” and “london” count as the same; surrounding spaces don’t matter.
- Sort A→Z and Z→A — natural sorting: numbers compare by value, so 2 comes before 10.
- Remove empty lines — including lines with only spaces.
- Trim spaces — at the start and end of every line.
- Reverse order — flips the list.
