About Random List Randomizer
🎲 Why better than Excel?
Many people use =RAND() in Excel, but it can have pseudo-random periodicity issues in older versions. This tool uses the browser's built-in Web Crypto API to generate cryptographically strong random numbers, combined with the Fisher-Yates Shuffle algorithm, ensuring every sort is truly fair, random, and unbiased.
💾 Auto-save Mechanism
Worried about losing data on refresh? Don't be! We have built-in auto-save. Your input and results are automatically encrypted and saved to localStorage as you type. Even if you close the tab, your list will be restored when you return.
