List Randomizer

List Randomizer Tool

This tool allows you to shuffle any list of items with a single click. Whether you’re drawing winners, organizing tasks, randomizing questions, or just want a fresh order for your list — this tool makes it simple and fast.

Enter each item on a separate line, click Randomize, and get your shuffled list instantly.

How the Randomizer Works

The tool uses the modern version of the Fisher–Yates Shuffle (a.k.a. Knuth shuffle). This algorithm ensures:

• Each permutation of the list is equally likely
• In-place, efficient O(n) time complexity
• Runs instantly in the browser with no server calls

This guarantees fair and unbiased randomization for any number of entries.

Classroom & Teaching Uses

• Shuffle student presentation order or project topics
• Create random pairs or groups
• Mix flashcards or quiz questions
• Introduce randomness into classroom activities

Technical Workflow

1. User inputs text (each item on a new line)
2. Input is split into an array of strings
3. Each string is trimmed and cleaned of empty entries
4. Fisher–Yates algorithm is applied to shuffle the array
5. The randomized list is displayed below the input
