Line Sorter - Online Sort Text Lines Alphabetically

Simply paste your text into the Input Text box, choose your sorting direction (A→Z or Z→A), and click the sort button. The sorted result instantly appears in the output box. You can also toggle options like Ignore Case, Remove Duplicates, and Skip Empty Lines to customize the sorting behavior. Use the Copy Result button to copy the sorted text to your clipboard.

By default, the Ignore Case option is enabled, meaning "Apple" and "apple" are treated as equal during sorting. If you disable this option, the sort becomes case-sensitive, and uppercase letters will be sorted before lowercase letters (following standard Unicode/ASCII ordering where 'A'=65 comes before 'a'=97). Toggle the Ignore Case switch in the options bar to change this behavior at any time.

Yes! Enable the Remove Duplicates toggle switch in the options bar. When activated, any duplicate lines in your input will be reduced to a single occurrence in the output. The tool preserves the first occurrence of each line when removing duplicates. This is particularly useful for cleaning up email lists, keyword research data, or any text dataset where uniqueness matters. The stats indicator will show you how many lines were removed.

The Reverse button flips the order of your text lines—the first line becomes the last, and the last becomes the first—without alphabetically sorting them. The Random button shuffles all lines into a completely random order using the Fisher-Yates algorithm. Both operations respect your Skip Empty Lines and Remove Duplicates settings. These are great for randomizing quiz questions, creating randomized playlists, or simply viewing your list from a different perspective.

There is no hard limit on the number of lines you can process. The tool runs entirely in your browser using JavaScript, so performance depends on your device's capabilities. In practice, most devices can comfortably handle tens of thousands of lines within seconds. For extremely large datasets (100,000+ lines), you may experience a slight delay. Since all processing happens locally, your data never leaves your device—ensuring complete privacy.

The easiest way is to click the Copy Result button, which copies all sorted text to your clipboard. You can then paste it into any text editor, spreadsheet (like Excel or Google Sheets), or document. Alternatively, you can manually select all text in the output box (Ctrl+A / Cmd+A) and copy it. If you want to re-sort the output with different settings, use the Use as Input button to transfer the sorted result back into the input box for further processing.
