How to Shuffle Text Online

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.

Frequently Asked Questions

How do I randomize the order of lines online?
Paste your lines into the editor (one item per line) and click Shuffle Lines. The tool rearranges all lines into a statistically fair random order instantly. Click again for a different order.
What is the Fisher-Yates shuffle?
Fisher-Yates is an algorithm that produces a truly unbiased random permutation of any sequence. Unlike sorting by a random number (which is biased), it gives every possible ordering an exactly equal probability. It runs in linear time — O(n) — making it fast for any list size.
Can I shuffle words instead of lines?
Yes — click Shuffle Words to scramble the word order within each line while keeping the lines themselves in place. Use Shuffle Chars to scramble individual characters within each word.
Is my text kept private when I shuffle it?
Yes. All shuffling runs entirely in your browser using JavaScript. Your text is never uploaded to any server. The tool works offline once the page has loaded.
