What This Tool Does
Paste any list of lines and the tool shuffles them into a random order using the Fisher-Yates algorithm with a cryptographically random seed, so every shuffle is genuinely unpredictable. Click shuffle again for a different order. The output can be copied or downloaded immediately.
When to Shuffle Lines
- Quiz prep: Randomize the order of answer options or questions to reduce sequence bias.
- Survey design: Shuffle survey items to counteract primacy and recency effects in respondents.
- Team rotation: Paste team member names and shuffle to create a random presentation or duty order.
- Random sampling: Shuffle a numbered list and take the first N items as a random sample.
- Playlist creation: Shuffle track names before importing into a playlist manager.
