Paste your text and sort lines alphabetically, numerically, by length, naturally, or randomly. Remove duplicates, trim whitespace, add line numbers, and more — all processed privately in your browser.
A feature-rich text sorter built for developers, writers, data analysts, and anyone who works with lists.
🚀
11 Sort Methods
Sort alphabetically (A-Z, Z-A), numerically (0-9, 9-0), naturally (file9 before file10), by line length, by word count, reverse the current order, or shuffle randomly using the Fisher-Yates algorithm for true unbiased randomization.
🧠
Natural Sort
Natural sorting orders items the way humans read them. File9 comes before file10, version v1.2 comes before v1.10, and Item 2 comes before Item 20. This uses the same algorithm as Windows Explorer and macOS Finder.
🔧
Smart Cleanup
Automatically trim whitespace from each line, remove empty blank lines, and eliminate duplicate entries. These preprocessing options ensure your output is always clean, deduplicated, and properly formatted.
#
Line Numbers & Prefix
Add sequential line numbers (1. 2. 3.) to sorted output, or append custom prefix and suffix text to every line. Perfect for creating numbered lists, bulleted lists, code arrays, or formatted data exports.

Frequently Asked Questions
Paste or type your text into the input area, select "A to Z" from the sort method dropdown, and click the "Sort Text" button. Your lines will be sorted in ascending alphabetical order instantly. Toggle "Case Insensitive" on if you want Apple and apple treated as equivalent.
Natural sorting orders text the way humans naturally read it. For example, "file9" comes before "file10", "v1.2" comes before "v1.10", and "Chapter 2" comes before "Chapter 20". Use it for sorting filenames, version numbers, numbered items, or any list with mixed text and numbers. It uses the same algorithm as Windows Explorer and macOS Finder.
Check the "Remove Duplicates" toggle option before clicking Sort. The tool will remove any lines that appear more than once, keeping only the first occurrence of each unique line. The statistics bar at the bottom shows exactly how many duplicates were removed.
Yes, completely safe. All processing happens entirely in your browser using client-side JavaScript. Your text is never transmitted to any server, never stored in any database, and never shared with any third party. When you close or refresh the page, all your data is permanently gone.
Yes. Use "Natural Sort" for lists with mixed text and numbers (e.g., "Item 2" before "Item 10"), or "Numeric Sort" for lists where items start with numbers (e.g., "2 apples" before "10 apples"). Both methods handle mixed content intelligently and fall back gracefully for non-numeric items.
The Fisher-Yates shuffle is a mathematically proven algorithm that produces a truly unbiased random permutation. Every click of the Shuffle button produces a different random ordering of your lines, with each possible arrangement having an equal probability. It is the gold standard for randomization.
Toggle "Line Numbers" to add sequential numbers (1. 2. 3.) before each line. You can also type custom text into the "Prefix" and "Suffix" input fields to prepend or append any characters to every line in the sorted output, such as bullets, dashes, semicolons, or code formatting.
