Quick answer
What does this tool do?
List Shuffler applies a Web Crypto Fisher–Yates shuffle to every line in a list. It can remove case-insensitive duplicates, restore alphabetical order, and export the current sequence.
- Algorithm
- Fisher–Yates shuffle
- Maximum list size
- 1,000 entries
- Duplicate cleanup
- Optional
- Output
- Text, copy and CSV
Why use this tool?
List Shuffler creates a new random order for any line-based list using a Web Crypto Fisher–Yates shuffle. Paste names, questions, tasks, agenda items or test cases, optionally remove case-insensitive duplicates and choose whether the displayed result should be numbered. The current input can also be sorted ascending or descending after a shuffle, copied as text or downloaded as CSV. Input limits and text cleaning prevent excessively large or unsafe entries, and ordinary processing stays on the device unless a share link is deliberately created. Every shuffle is independent, so repeatedly shuffling until a preferred order appears defeats the purpose of a neutral result. Define the eligible list and duplicate rule first, perform one shuffle when fairness matters and preserve only the minimum record needed for the activity.
How to use it
- Paste one item per line.
- Choose duplicate removal and numbering.
- Shuffle the list.
- Copy, sort or download the current order.
Common use cases
- Randomize an agenda
- Mix quiz questions
- Create a task order
Practical examples
- Randomize quiz questions before printing.
- Mix a task backlog into a fresh review order.
- Shuffle player names before assigning numbered positions.
How it works
Random values come from window.crypto.getRandomValues(). Lists are shuffled with an unbiased Fisher–Yates process. For a wheel, the result is chosen before the animation; for weighted entries, each positive weight defines its share of the total probability.
Limits to understand
- Sorting after shuffling replaces the random order.
- Duplicate cleanup is based on normalized display text.
- The shuffle does not assign tasks to particular skills.
Privacy
Input and results stay inside this browser during normal use. Local saving is optional. If you select Create Share Link, the visible list and settings are uploaded under a hard-to-guess token and expire automatically.

List Shuffler FAQ
Is my list uploaded?
No. Entries are processed in your browser unless you explicitly create a share link.
What kind of randomness is used?
The browser Web Crypto API supplies unbiased random values. Wheel animation only reveals a result chosen in advance.
Does it work on phones?
Yes. The controls, results and wheel adapt to current mobile browsers and keyboard navigation.
Can I reuse my settings?
Yes. Device storage can remember recent settings unless you turn off local list saving.
Is this suitable for a certified lottery?
No. It is a general-purpose classroom, work, event and decision tool, not a regulated drawing system.
