List Randomizer
List Randomizer mix names randomly shuffle pasted lines randomize item orderShuffle complete lines locally
Enter one item per line and choose Randomize list. Blank lines are removed, duplicates stay, and every remaining line appears exactly once in a new randomized order.
What gets randomized
Each trimmed nonblank line is one item. The tool never breaks a line into words or fields. Two identical lines remain two separate entries, which matters when they represent separate tickets, repeated assignments, or weighted chances intentionally created by duplication.
Shuffle method
The page uses a Fisher–Yates shuffle. Starting at the end of the list, it chooses a random eligible position and swaps the two entries until every position has been handled. Random integers come from the browser's Web Crypto source with rejection sampling to avoid simple modulo bias.
Worked example
Enter Ava, Ben, Chen, and Dev on separate lines. One shuffle might return Chen, Ava, Dev, Ben. Another can return a different order, including the original order by chance. Both are valid because randomization does not promise that every item moves.
Random order is not balanced assignment
A shuffle gives each ordering an equal mathematical opportunity under its random source. It does not balance skills, preferences, history, geography, conflicts, or group sizes. Use the Random Team Generator when the job is dividing people into teams rather than ordering one list.
Fairness and audit limits
Web Crypto is suitable for unbiased browser-side selection, but this page provides no public seed, signed record, independent witness, or reproducible audit trail. Do not use an unrecorded browser shuffle where law, money, prizes, formal elections, or regulated procedures require verifiable selection.
Privacy and limitations
Items are processed locally and are not intentionally uploaded or saved. Browser extensions, clipboard history, and shared-device access remain outside the tool. Very large lists are limited by the text field and device memory. Reloading the page discards the current result.
List Randomizer FAQ
Can the same item appear twice?
Only if it appeared twice in the input; every input line is retained once.
Why did an item stay in the same position?
A valid random permutation can leave one or more items where they started.
Can I reproduce a shuffle later?
No. This tool does not accept or record a seed.
