Shuffle Text
Randomize lines, words, or characters — true random order using Fisher-Yates
How to Shuffle Text Online
- Shuffle Lines — randomizes the order of every line. One item per line. Click multiple times for a different order each time.
- Shuffle Words — keeps lines in place but scrambles the words within each line. Great for anagram exercises or word-order drills.
- Shuffle Chars — scrambles individual characters within each word. Useful for creating cipher or spelling-challenge puzzles.
- Keep blanks toggle — by default blank lines are removed before shuffling. Enable "Keep blanks" to preserve them.
- Undo — restores the previous state if you don't like the result.
What Can You Use a Text Shuffler For?
Randomize Survey or Quiz Questions
Paste your questions one per line and shuffle them before distributing to students or respondents. Randomizing question order reduces answer-copying and position bias in survey results.
Raffle & Lottery Draws
Add every participant's name on a separate line, shuffle, and pick the top entry as your winner. Fairer than manual drawing and fully transparent.
Flashcard & Study Deck Randomization
Paste your study terms or vocabulary words and shuffle them to avoid the "primacy effect" — where items at the top of a list are remembered better than those at the bottom.
Playlist & Reading List Shuffling
Can't decide what to read or watch next? Add your options as a list and let the shuffler decide for you.
Anonymizing Entry Order
Shuffle a list of names or submissions before publishing results to avoid alphabetical or submission-order bias.
Word Scramble Puzzles
Use Shuffle Words or Shuffle Chars to create scrambled word exercises for language learners or puzzle makers.
True Random Shuffling — Fisher-Yates Algorithm
This tool uses the Fisher-Yates shuffle (also known as the Knuth shuffle), the gold standard for generating an unbiased random permutation of a sequence.
Unlike a naive sort-by-random approach (which is subtly biased), Fisher-Yates works by iterating from the last element to the first and swapping each element with a randomly selected element at or before it. Every possible ordering has exactly equal probability.
The algorithm runs in O(n) time — it is instant even for lists with thousands of entries.
