About This Tool

The List Randomizer shuffles list order or sorts alphabetically. It supports three arrangement modes — random shuffle, ascending, and descending — along with options for auto-numbering, trimming spaces, removing empty lines, and deduplication for flexible list processing. All operations are performed locally in your browser — your list content is never uploaded to any server.

Frequently Asked Questions

What shuffle algorithm is used?

The tool uses the Fisher-Yates shuffle algorithm, a classic equal-probability random permutation algorithm that ensures every element has an equal chance of appearing in any position, producing completely random and fair results.

What does the deduplication option do?

When enabled, duplicate entries in the list are reduced to only their first occurrence, with subsequent repeats automatically removed. This is very useful when processing lists that contain duplicate data.

How does the auto-numbering feature work?

Auto-numbering is enabled by default, adding a sequence number (e.g., 1. 2. 3.) before each sorted item. If you don't need numbering, simply uncheck the 'Number items' option to output a plain list.

Is sorting case-sensitive?

No. Sorting uses case-insensitive comparison, so Apple and apple are treated as having the same priority, ensuring the sort results are more intuitive.

Can I shuffle multiple times for different results?

Yes. Each click of the 'Shuffle' button generates a brand new random permutation, so you can click repeatedly until you get a satisfactory result.
