When you want to shuffle test data to ensure unbiased processing in your applications.
When you need to quickly reorder lines in a document for brainstorming or creative writing.
How it works
1Paste your text into the input area, with each item on a new line.
2Adjust settings like 'Preserve Empty Lines' or 'Trim Lines' to clean up your data.
3Optionally enter a numeric seed to ensure the randomization is reproducible.
4Click the process button to generate your shuffled text output.

Examples
1. Randomizing Quiz Questions
Teacher
Background
A teacher has a list of 20 quiz questions and wants to create three different versions of the quiz to prevent students from sharing answers.
Problem
Manually reordering the questions is tedious and prone to human error.
How to use
Paste the list of questions into the input area and click randomize.
Outcome
The tool outputs the same 20 questions in a completely new, randomized order.
2. Creating Randomized Test Data
Software Developer
Background
A developer needs to test a UI component that displays a list of user names, ensuring the layout remains stable regardless of the order.
Problem
The original list is sorted alphabetically, which doesn't reflect real-world usage.
How to use
Paste the list of names, enable 'Trim Lines' to ensure clean formatting, and click randomize.
trimLines: true

FAQ
Can I keep empty lines in their original positions?
Yes, simply enable the 'Preserve Empty Lines' checkbox to ensure blank lines remain fixed while other content is shuffled.
Does this tool remove extra spaces?
If you enable the 'Trim Lines' option, the tool will automatically remove leading and trailing whitespace from every line.
How can I get the same random result twice?
Enter a specific number in the 'Random Seed' field. Using the same seed with the same input will always produce the exact same shuffled output.
Is there a limit to how much text I can randomize?
The tool is designed for standard text processing; for extremely large files, ensure your browser has sufficient memory to handle the input.
Does this tool store my text?
No, all processing happens locally in your browser, and your text is not uploaded or stored on any server.
