Randomly shuffles (randomizes) the order of lines in your text using the Fisher-Yates algorithm for true randomness. Every shuffle produces a different order.
Common Use Cases
Randomizing quiz question order, shuffling word lists for flashcard practice, creating random playlists, randomizing survey options, and generating test data in random order.
How It Works
Splits text on newlines, applies the Fisher-Yates shuffle algorithm for unbiased random ordering, and rejoins the shuffled lines.
