Remove duplicate lines

Tidies a list of lines: removes extra spaces, empty lines and repeats and can sort alphabetically.

1. Paste a list, one item per line.
2. Switch on what you need.
3. Copy the result.

• A repeat means exactly the same line.
• Sorting ignores case and understands numbers: 2 comes before 10.

How many lines can I paste?

As many as the page can hold: thousands work fine.

Are lines uploaded?

No, everything stays in your browser.
