Last updated: September 2026List Tools is a free browser-based tool that lets you sort, shuffle, reverse, number, deduplicate, and transform lists with multiple formatting options. It processes everything locally in your browser using JavaScript, so your data never leaves your device. No sign-up, no installation, and no server uploads required — just open the tool and start using it immediately.
This tool is particularly useful when organizing data lists, preparing CSV columns, randomizing quiz answers, or formatting text lists for documents. Since it runs entirely in your browser, it works offline after the page loads and keeps your data completely private.
