Sort, reverse, shuffle and remove duplicate lines.
Free. Runs in your browser: nothing you enter or open is uploaded.
Natural order compares numbers inside the text by value, so item 2 comes before item 10. Shuffle uses your browser's cryptographic random number generator, so every order is equally likely.
How to use it
- Paste your list with one item per line.
- Choose an order and tick the clean-up options you want: remove duplicates, trim spaces, drop empty lines.
- Copy the result, or press Use as input to keep working on it.
Questions
What is natural sort?
Plain alphabetical sorting compares character by character, so 10 comes before 2. Natural sort reads the numbers as numbers, which is what people expect for file names, versions and numbered items.
How does case sensitive sorting work?
When it is off, Apple and apple sort together as if they were the same. When it is on, capital letters and small letters are treated as different and kept apart.
Which copy is kept when duplicates are removed?
The first time a line appears is kept and later copies are dropped, before sorting. With Ignore case ticked, Apple and apple count as the same line.
Is the shuffle really random?
Yes. It uses the Fisher-Yates method with numbers from the Web Crypto random generator, so it is fair enough for draws and giveaways.
