Word sorter

Splits words and sorts A-Z or Z-A, with optional case-insensitive mode.

Overview

Sorting a list of words sounds trivial until you try to do it robustly in software. Donald Knuth dedicated an entire volume of The Art of Computer Programming to sorting algorithms — Volume 3, Sorting and Searching, published in 1973 and revised in 1998. That volume details more than a dozen sorting algorithms, including mergesort, heapsort, quicksort, and radix sort, each with different trade-offs of time, space, and worst-case behavior. Efficient sorting is a solved problem in terms of algorithms — timsort, the default in Python and Java, is practical and stable — but the criteria for sorting human text remain an area full of surprises.

Simple lexicographic sorting by Unicode code point produces counterintuitive results for accented text: `A` (U+0041) comes before `a` (U+0061) by numeric default, putting all uppercase before all lowercase. Accented characters complicate things further: `ã` (U+00E3) comes numerically after `z` (U+007A), breaking any dictionary-style ordering. The correct solution is JavaScript's `Intl.Collator` API with the appropriate locale, which knows the language's comparison rules and treats accented characters as variants of the base letter. Natural sorting for strings mixing text and numbers is yet another problem: `item2` should come before `item10`, but lexicographic sorting places `item10` first because `1` comes before `2`. Natural sort algorithms solve this by segmenting the string into numeric and text parts and comparing them separately.

Sorting words is more useful than it first appears in daily development work. Import lists in Python and CSS (properties), documentation glossaries, lists of tags or categories, string arrays in code, permission lists in configuration files — all benefit from consistent alphabetical ordering. Project conventions often enforce import sorting: ESLint has a `sort-imports` rule, isort organizes Python imports, and Prettier sorts CSS properties. When a file is edited by multiple people over time, maintaining alphabetical order eliminates a category of merge conflicts where the only real difference is the position of a line. This tool performs that sorting in the browser for any list of words you need to organize quickly.
