Yes, select the 'Scramble Letters (keep first/last)' mode to shuffle only the internal characters of each word. ### Does the tool support preserving sentence structure? Yes, by enabling 'Preserve Spaces', the tool will keep the original word spacing intact while scrambling the characters within. ### Can I get the same scrambled result twice? Yes, by entering a specific number in the 'Random Seed' field, you ensure that the same input always produces the same scrambled output. ### What is the difference between 'Scramble Letters' and 'Scramble All Characters'? 'Scramble Letters' focuses on rearranging alphabetic characters, while 'Scramble All Characters' treats every symbol, including punctuation and numbers, as part of the shuffle. ### Is there a limit to the amount of text I can scramble? The tool is designed to handle standard text blocks efficiently; however, extremely large documents may perform better if processed in smaller segments. ## Related tools - [Data Noise Injection](https://elysiatools.com/en/tools/data-noise-injection): Inject various types of noise into text data for testing purposes.
