Frequently Asked Questions
How does line shuffling work?
The tool uses the Fisher-Yates shuffle algorithm to randomly reorder lines. Each line has an equal probability of appearing in any position in the output.
Will all lines appear in the shuffled output?
Yes, all input lines are preserved in the shuffled output. No lines are added or removed - they're simply reordered randomly.
Can I shuffle the same input multiple times?
Yes, clicking "Shuffle" multiple times will produce different random arrangements each time. Each shuffle is independent with a new random seed.
What are common uses for shuffling lines?
Line shuffling is useful for randomizing lists, creating randomized test questions, mixing playlists, game development, creative writing prompts, and data anonymization.
