Sort Lines Online

🔤 How to Sort Lines Alphabetically

Paste or type one item on each line. Select Alphabetical as the sorting method and choose either ascending or descending order.

Ascending alphabetical order places earlier text first, while descending order reverses that ordering.

By default, alphabetical comparisons are case-insensitive. Enable Case sensitive when uppercase and lowercase differences should affect the comparison.

🔢 Natural Sorting for Numbered Text

Ordinary text sorting can produce unexpected ordering when lines contain numbers. For example, a purely lexical comparison may place “Item 10” before “Item 2.”

The Natural / Numeric option uses number-aware comparison so numbered items are usually arranged in the order people expect.

📏 Sort Lines by Length

Choose Line Length when you want to organize text according to the number of characters in each line.

If the Trim line spaces option is enabled, leading and trailing whitespace is removed before the line length is measured.

🧹 Clean Lines While Sorting

Sorting often goes together with basic list cleanup. The available options let you prepare the lines before they are sorted.

• Trim line spaces: removes whitespace from the beginning and end of each line.
• Remove blank lines: excludes lines that are empty after optional trimming.
• Remove duplicates: keeps the first occurrence of repeated lines before sorting.
• Case sensitive: makes letter case relevant to alphabetical and duplicate comparison.

These options can be useful when cleaning copied lists, names, keywords, inventory labels, filenames, notes or other line-based text.

🔁 How Duplicate Removal Works

When Remove duplicates is enabled, repeated lines are removed before the final sorting step.

With case sensitivity disabled, lines such as “Apple” and “apple” are treated as duplicates. The first version appearing in the input is retained.

With case sensitivity enabled, “Apple” and “apple” are considered different lines.

🎲 Randomize or Shuffle Lines

The Random / Shuffle method rearranges the current lines into a randomized order instead of alphabetical or length order.

Because the order is randomized, pressing Sort Lines again can produce a different arrangement.

This can be useful for casually mixing lists, prompts, names, practice items or other non-security-sensitive text.

🌍 Alphabetical Order and Language

The alphabetical and natural sorting modes use the browser’s locale-aware text comparison. The exact ordering of some accented characters, symbols or non-English text can therefore depend on the browser environment and language rules available on the device.

For ordinary English-language lists, the default case-insensitive mode generally provides familiar alphabetical ordering.

💼 Common Uses for a Line Sorter

A line sorting tool can help organize many kinds of plain-text lists, including:

• names and contact lists;
• keywords and tags;
• product or inventory labels;
• filenames and folder lists;
• study terms and vocabulary;
• task or reference lists;
• numbered item names;
• copied spreadsheet values stored one per line.

The sorter treats each newline-separated entry as one line. It does not interpret the input as spreadsheet columns, CSV fields or a database table.

🔒 Browser-Based Line Sorting

This tool is designed to process the text entered into the sorter using browser-side JavaScript. Sorting, trimming, duplicate removal and line counting are performed by the page without requiring an account.
