Same pieces, new order.

What it does

A string randomizer permutes text. It takes the pieces you give it and returns them in a new order, without adding, deleting, or substituting anything. The pieces can be individual characters, or blocks separated by a delimiter such as a space or a comma.

That constraint is what separates it from a text generator. A generated string can contain letters that were never in the input; a shuffled string is a rearrangement of the input. It is useful for word puzzles, sample data, design mockups, and testing whether a layout can survive unpredictable content.

Characters or blocks

Leave the delimiter blank to shuffle characters. Enter a space to shuffle words. Enter a comma to shuffle comma-separated values, or a longer string such as | to shuffle around a custom marker. The delimiter is matched literally, not as a regular expression, so characters such as dots and brackets need no escaping.

Character mode works on grapheme clusters where the browser provides them. A flag emoji, a skin-tone modifier, or a family joined with zero-width joiners should stay in one piece rather than being split into code points that no longer render correctly. In an older browser the tool falls back to code points. Block mode never splits inside a block, so the delimiter is the only boundary that matters.

Per line or whole text

Per-line mode is the default. Each line is shuffled independently, and the line breaks stay between the results. That mirrors a list of strings: one label per line, one shuffled label per line. Whole-text mode merges the lines first and shuffles the entire sequence. It is the right choice when the line breaks are not meaningful, and the wrong choice when they are.

Repeated delimiters can create empty blocks. For example, splitting “a,,b” on a comma produces an empty piece between the two commas. “Ignore empty blocks” keeps the shuffle from spending a position on that empty piece; turn it off if the exact delimiter structure is part of the data.

The four words are still there, each exactly once. Only their order changed. Pressing Randomize again would produce another permutation, possibly the original order. A shuffle does not guarantee that every item moves; it guarantees a uniformly chosen arrangement.

Six letters in, six letters out. The output is harder to read but easy to analyze: the letter counts are unchanged, so it is not a cipher and not a secure way to hide a word. It is a rearrangement, not a substitution.

The emoji is one grapheme cluster, so it moves as a unit rather than being split into surrogate halves. The ASCII letters move around it. In a browser without grapheme segmentation the fallback may treat the emoji as multiple code points; the page shows the output, so you can check before using it.

Limits worth knowing

• It is not encryption. A permutation preserves the characters, their frequencies, and often the words. Anyone can inspect or unscramble it with enough context.
• It uses pseudo-randomness, not a guarantee. The shuffle draws from the browser’s random source, with a fallback in old environments. It is fine for puzzles and mock data, not for cryptographic keys or audited lotteries.
• There is no seed. You cannot reproduce a particular shuffle from the page. Save the output if you need it later.
• The output is a permutation, not a word unscrambler. It does not consult a dictionary, rank possible words, or restore the original order. A random arrangement can be identical to the input by chance.
• Whole-text mode changes the shape of the document. Line breaks can move or become part of a block. Use per-line mode when the lines are records.
