What Shuffle Integers can do:

This tool randomizes a list of numbers using a clean and unbiased shuffle. It preserves all valid entries and updates in real time. You control whether results appear line-by-line or on one line, and whether to include invalid entries in the final output.

Example:

Input:

1
2
3
4
5

Output (One per line ON):

3
1
5
2
4

Output (One per line OFF):

3 1 5 2 4

Common Use Cases:

Use this tool for randomizing test data, building sample inputs, preparing quizzes, shuffling datasets, or simply mixing up a list of numbers for clean, client-side use. Great for developers, teachers, and data workers.

Useful Tools & Suggestions:

After using Shuffle Integers, try Sort Integers to restore order or spot patterns after the mix. And if you’re shuffling for testing purposes, Generate a Multi-integer Sequence gives you a clean base set to start with.
