Text Sort & Deduplicate
Sort lines alphabetically, numerically, or by length. Remove duplicates, trim whitespace, and filter empty lines.
About This Tool
The Text Sort & Deduplicate tool is a free, browser-based utility designed for developers, writers, and data analysts who need to quickly organize and clean up lists of text. Whether you're sorting a list of hostnames, deduplicating log entries, cleaning up CSV columns, or arranging items for a configuration file, this tool handles it in milliseconds.
All processing happens entirely in your browser using native JavaScript. Your data never leaves your machine — there are no server round-trips, no logging, and no third-party analytics on your input. This makes it safe for sensitive data such as server lists, internal URLs, credentials files, and database exports.
The tool supports seven sort modes: alphabetical ascending and descending, numeric ascending and descending (which correctly handles mixed text and number lines), line length in both directions, and random shuffle for when you need to randomize the order. Additional options let you remove duplicate lines, trim leading and trailing whitespace from each line, filter out empty lines, and toggle case-insensitive sorting and deduplication.
A live statistics bar shows you the total number of lines, how many unique lines exist, and how many duplicates or empty lines were removed — giving you instant feedback on the transformation. The output updates in real time as you type or change any option, so there is no need to press a process button. Common use cases include preparing wordlists, sorting dependency lists, cleaning up exported data, organizing translations, and alphabetizing glossaries or reference tables.
How to Use
- Paste or type your text into the Input panel on the left. Each line is treated as a separate item.
- Choose a Sort Mode from the dropdown: alphabetical, numeric, by line length, or random shuffle.
- Toggle the checkboxes to remove duplicates, trim whitespace, remove empty lines, or enable case-insensitive sorting.
- The Output panel on the right updates in real time as you type or change any option.
- Review the stats bar to see how many lines were processed, how many are unique, and how many duplicates or empty lines were removed.
- Click Copy to copy the output to your clipboard, or use the keyboard shortcut Ctrl+Shift+C.
- Click Sample to load example text, or Clear to reset both panels.
FAQ
Is my data safe?
Yes. All sorting and deduplication is performed client-side in your browser using JavaScript. No data is sent to any server, making it safe for sensitive information.
How does numeric sorting work with mixed text and numbers?
Lines that start with a valid number are sorted by their numeric value. Lines that are not numbers are placed after the numeric lines and sorted alphabetically among themselves.
What does "case insensitive" affect?
When enabled, case-insensitive mode causes sorting to ignore letter case (so "Apple" and "apple" are treated as equivalent). It also affects duplicate removal: "Apple" and "apple" would be considered duplicates and only the first occurrence is kept.
Can I handle very large text files?
The tool works well for text up to tens of thousands of lines. For extremely large inputs (hundreds of thousands of lines), performance depends on your device. Since all processing is done in real time, very large inputs may cause a brief delay.
How does random shuffle work?
Random shuffle uses the Fisher-Yates algorithm to produce a uniformly random permutation of your lines. Click the Re-shuffle button to generate a new random order without changing any other settings.
What keyboard shortcuts are available?
Press Ctrl+Shift+C to copy the sorted output to your clipboard at any time.
Does trimming whitespace affect sorting?
Yes. When "Trim whitespace" is enabled, leading and trailing spaces are removed from each line before sorting and deduplication. This means lines that differ only by whitespace will be treated as identical when removing duplicates.
