Line Sort & Deduplicate

Line Sort & Deduplicate is a versatile tool for organizing text data on a per-line basis.

It offers 6 sort modes — alphabetical ascending (A-Z), descending (Z-A), numeric, natural alphanumeric (where v1.10 comes after v1.9), by line length (shortest or longest first), and random shuffle — covering every text sorting need. Natural sort is especially useful for version numbers, filenames, and mixed alphanumeric content that would otherwise sort incorrectly with standard alphabetical ordering.

Combined with automatic duplicate removal, empty line deletion, and per-line whitespace trimming, it lets you quickly clean up messy lists, log files, and data exports created by copy-paste workflows. You can also toggle case sensitivity for both sorting and deduplication.

Whether you are a developer organizing code output and version numbers, a marketer cleaning customer lists, or a researcher preparing datasets, this tool handles it all. Every operation runs entirely in the browser, so your text — including personal or sensitive data — never leaves your device.
