Number Sorter — Frequently Asked Questions

How many numbers can it sort?+

Practically unlimited. Browser-based sorting handles millions of numbers in seconds. For very large datasets (100M+), use a dedicated tool.

What separators work?+

Commas, spaces, tabs, and newlines all work. Mix and match freely: '1, 2 3\n4' → [1, 2, 3, 4].

What's the difference between mean and median?+

Mean is the average (sum/count). Median is the middle value when sorted. Median is more robust against outliers: [1,2,3,4,100] has mean=22 but median=3.
