Line Sorter

The Line Sorter takes a block of text and reorders it line by line. You can sort alphabetically, numerically, or by line length, reverse the order, or shuffle randomly, and clean the list at the same time by trimming whitespace, dropping blank lines, and removing duplicates.

Sorting lists by hand is tedious and error-prone, especially with mixed case, numbers, or duplicate entries. This tool handles all of that instantly: it uses a natural, case-aware comparison so that "item2" comes before "item10", and it can fold case so "Apple" and "apple" are treated as the same entry when removing duplicates.

Everything runs in your browser. Paste your list, choose how to sort and clean it, and copy the result. No account, no uploads, and it keeps working offline once the page has loaded - safe for sensitive lists that should never leave your machine.

Alphabetical and natural sorting differ in one way that matters constantly. A plain alphabetical sort compares character by character, so file10 comes before file2, because the character 1 sorts before 2. Natural sorting reads runs of digits as numbers and puts file2 first, which is what a person expects from a list of filenames or versions. Case is the other axis: an uppercase letter sorts before every lowercase letter in raw byte order, so a case-sensitive sort separates Apple from apple entirely rather than placing them together. Removing duplicates compares whole lines, so two lines differing only by trailing whitespace are not duplicates, which is why the cleaning options exist and are worth running first. Sorting happens in memory, so very large files are bounded by the tab.
