Sort Text Lines

This text organization tool sorts lines of text alphabetically, numerically, by line length, or in reverse order using efficient comparison-based sorting algorithms implemented in JavaScript. The sorter supports case-sensitive and case-insensitive modes, natural number sorting that correctly orders "item2" before "item10," and locale-aware sorting that respects language-specific character ordering rules via the Intl.Collator API.

The tool handles multiple input scenarios including removing duplicate lines during the sort, trimming whitespace from each line before comparison, ignoring blank lines, and sorting by a specific column or delimiter position within each line. For large inputs, it employs a stable sort algorithm that preserves the relative order of lines that compare as equal, which is critical for multi-key sorting operations.

Developers organizing configuration files, data analysts cleaning CSV exports, system administrators sorting log entries, and writers arranging lists all benefit from this utility. The processing runs entirely within your browser, making it safe for sorting proprietary data, server logs containing IP addresses, or any text you would not want uploaded to a third-party service.
