Shuffle Lines

Summary

Shuffle Lines randomly reorders every line in your text using the Fisher-Yates (Knuth) algorithm, which guarantees an unbiased permutation. Paste your list, optionally strip blank lines or duplicate entries, then click Shuffle to get an instantly randomized result you can copy with one click.

How it works

1. Paste or type your text into the input area — one item per line.
2. Toggle "Remove blank lines" to drop empty lines before shuffling.
3. Toggle "Remove duplicates" to keep only the first occurrence of each line.
4. Click "Shuffle Lines" to randomize the order using Fisher-Yates.
5. Review the result on the right, then click "Copy Result" to copy it.
6. Click "Shuffle Again" to get a different random order from the same cleaned list.
