Text Shuffler

What this tool does

The Text Shuffler randomly rearranges the units of your text using a Fisher-Yates shuffle — the same algorithm used in card games and statistical sampling tools. You choose what to shuffle: individual words across the whole text, the lines of a multi-line block, or the characters of the input one by one. Paste your text, pick a scope, and hit Shuffle again each time you want a new random arrangement. The output is always a true permutation, meaning every unit from the original appears exactly once in the result.

Why you might need it

Random shuffling of text turns out to be useful in more situations than you might expect. Writers use word shuffling to break habitual sentence patterns and spark new ideas during a creative block — seeing familiar words in an unexpected order can trigger a phrase that would never have occurred in linear thinking. Teachers use it to scramble the words of a sentence for students to reconstruct, which reinforces understanding of word order and grammar.

Line shuffling is handy when you need to randomise the order of a list for a lottery, a raffle, a random reading order, or a randomised test. It is also useful for preparing training and validation splits of small datasets without writing any code. Character shuffling, while producing mostly unreadable output, is useful in puzzle design, typography experiments, and testing how a renderer handles arbitrary Unicode sequences.

How to use it

1. Choose a scope: Words shuffles the tokens separated by whitespace, Lines shuffles the rows of a multi-line input, and Characters shuffles every individual character including emoji.
2. Type or paste your text into the input box — the shuffled result appears immediately.
3. Click Shuffle again to get a new random arrangement without changing the input.
4. Click Load sample to try the tool on a pre-loaded sentence.
5. Use Copy output to grab the shuffled text, or Clear to start over.

Common pitfalls

Words mode splits on any run of whitespace and rejoins with single spaces, so punctuation attached to a word stays attached to it. “fox,” shuffled into the middle of a sentence keeps its comma. If you need a perfectly punctuated result after shuffling, you will need to tidy the output by hand.

Lines mode treats blank lines as items to shuffle, so if your text has empty lines between paragraphs they may end up between unrelated lines in the output. Remove blank lines before shuffling (the Sort Lines tool has an option for this) if that is a concern.

Character mode produces output that is almost always unreadable text — it is designed for use cases that care about raw characters rather than words. The output includes every whitespace and punctuation character from the original, also shuffled.

Tips and advanced use

For a randomised reading list or task order, paste one item per line and use Lines mode. Each click of Shuffle again produces a fresh order. Copy the result into your document, notes app, or task manager.

Writers can use Words mode on a draft sentence as a creative prompt: the shuffled form rarely makes grammatical sense, but it can surface an unexpected pairing of a subject and a verb, or an adjective next to an unusual noun, that becomes the seed of a new line. It is a low-stakes way to break a creative block for a few seconds.

For educators building scrambled-sentence exercises, paste a clean sentence in Words mode, shuffle until you get an arrangement that is genuinely non-obvious, and copy it into the exercise sheet. Because the tool runs entirely in the browser with no data leaving your device, you can safely paste real student names, unpublished questions, or other sensitive content.
