How It Works

The shuffle algorithm uses the Fisher-Yates shuffle (also known as Knuth shuffle), which is an unbiased randomization algorithm. This ensures that every possible permutation of the input items has an equal probability of being generated.

Examples
Input (ordered list): 
apple
banana
cherry
date
elderberry
Output (shuffled): 
cherry
apple
elderberry
banana
date
Tips
  • Duplicates: Enable "Remove duplicates" to ensure each item appears only once
  • Format Conversion: Use different input/output formats to convert while shuffling
  • Multiple Shuffles: Click shuffle multiple times to get different random orders
  • Random Sampling: Shuffle a large list, then take the first N items for a random sample
