List Shuffler — Randomize, Sort, and Transform Any List Instantly
Our free list shuffler lets you paste any list of items and apply instant transformations — shuffle into random order, sort alphabetically, reverse, or deduplicate. Perfect for randomizing attendee lists, shuffling playlists, sorting raw data, or removing duplicate entries from a CSV export. The split two-panel layout shows your input on the left and transformed output on the right, with a one-click copy button.

- Toggle Number Items if you want each output line prefixed with a sequential number (1. Item).
- Click Copy in the top right of the Output panel to copy the transformed list to your clipboard.

Frequently Asked Questions
How are items shuffled randomly?
The List Shuffler uses the Fisher-Yates (Knuth) shuffle algorithm, which produces a uniformly random permutation of the input list. Every possible ordering of the items is equally likely.
What does Deduplicate do?
Deduplicate removes all duplicate items from the list, keeping only the first occurrence of each unique entry. The comparison is case-sensitive, so "Apple" and "apple" are treated as different items.
Can I shuffle a large list?
Yes. There is no enforced limit on list size. For very large lists (thousands of items), the transformation is still instantaneous. The output panel becomes scrollable for long results.
Can I undo a transformation?
Yes. Every transformation is stored in the History section at the bottom of the page. Click the Restore button next to any past entry to bring that result back into the output panel.
