Need to fairly randomize a list but worry about human bias? This tool uses the Fisher-Yates algorithm to completely shuffle your input text lines, treating each line as an independent item. The result is output as plain text with one item per line, ensuring unpredictability and fairness. It is ideal for raffles, giveaways, data shuffling, and any scenario requiring true randomness.
How do you guarantee true randomness?
We use the Fisher-Yates algorithm, which iterates through the list and randomly swaps element positions, ensuring that every possible permutation has an equal chance of appearing.
What are the input format requirements?
You must enter one independent item per line. Blank lines are treated as valid items and will be included in the shuffle. The tool supports text, numbers, or mixed content.
Blank lines are treated as valid items; be mindful of browser performance when processing extremely long lists; ensure your operating environment is secure when handling sensitive data; results are not saved in history, so please copy your output promptly.
For data science applications, we recommend processing large datasets of 10,000+ items in batches. Typical input/output example: Inputting three lines "A B C" will output one of the 6 possible permutations, such as "B C A" or "C A B", with each combination having exactly a 1/6 probability of occurring.
