What this tool does
The Sort Lines tool takes any block of text and reorders each line according to a method you choose. Paste a list of names, numbers, file paths, URLs, words, or any other line-separated content, pick a sort method, and get a cleanly ordered result in seconds.
Sorting text manually is tedious and error-prone, especially with long lists. This tool handles it instantly, whether you need strict alphabetical order for a directory listing, numerical order for a set of scores, or a random shuffle for a raffle draw.
All processing happens entirely in your browser. Nothing is sent to any server, so your data stays private.
Sort methods explained
**Alphabetical (A-Z):** Sorts lines in ascending lexicographic order using locale-aware comparison. Numbers and punctuation sort before letters by default.
**Alphabetical (Z-A):** The reverse of A-Z, placing lines that start with Z or the highest characters at the top.
**Numerical (Low to High):** Parses each line as a floating-point number and sorts from smallest to largest. Lines that cannot be parsed as numbers fall back to alphabetical comparison.
**Numerical (High to Low):** Parses each line as a number and sorts from largest to smallest. Useful for ranking scores, prices, or measurements.
**By Length (Shortest First):** Sorts lines by character count, putting the shortest lines at the top. Helpful when you want to see compact entries before longer ones.
**By Length (Longest First):** The reverse of shortest-first. Useful for identifying the most verbose entries in a list.
**Reverse Order:** Flips the current order of lines without any alphabetical or numerical logic. The last line becomes the first. Useful when your data is already in an order you want to invert.
**Shuffle Randomly:** Randomizes the order of lines using the Fisher-Yates algorithm, which produces a fair, unbiased random order. Every click produces a different result.
**Case Sensitive toggle:** When enabled, uppercase letters sort before lowercase (A before a). When disabled, case is ignored and "apple" and "Apple" are treated as equivalent for sorting purposes.
Who should use this
- **Developers:** Sort import statements, configuration keys, environment variables, or log lines for easier reading and diffing. - **Writers and editors:** Alphabetize glossary terms, bibliography entries, or a list of character names. - **Data analysts:** Quickly rank lists of values, scores, or measurements without opening a spreadsheet. - **Teachers and event organizers:** Shuffle a list of student names or participant entries for random assignment. - **Sysadmins:** Sort server lists, hostnames, or IP addresses for inventory management. - **Anyone with a list:** If you have a set of items that need ordering, this tool handles it without any software installation.
How to use
1. Paste your text into the input box, with one item per line. 2. Choose a sort method from the dropdown menu. 3. Optionally enable "Case sensitive" if you need uppercase letters to sort before lowercase. 4. Click "Sort Lines" to apply the sort. 5. Review the sorted output in the result panel. 6. Click "Copy" to copy the sorted text to your clipboard.
Tips and best practices
**Blank lines:** Blank lines are treated as empty strings. They sort before any non-empty line in A-Z order and after all lines in Z-A order. If you want to exclude blank lines from the result, remove them before sorting or use a dedicated blank line removal tool first.
**Mixed content:** If your list contains both numbers and text, the Numerical sort falls back to alphabetical comparison for non-numeric lines. For a pure numeric sort, make sure all lines contain only numbers.
**Duplicates:** Sorting does not remove duplicate lines. If you want unique lines only, deduplicate the list first and then sort.
**Large lists:** The tool handles thousands of lines without performance issues since all processing runs locally in the browser.
**Re-sorting:** You can sort an already-sorted list again with a different method. For example, sort alphabetically first, then by length to see how lengths are distributed within the alphabetical order.
FAQs
Q: Does sorting preserve blank lines? A: Yes, blank lines are treated as empty strings and sorted accordingly. Use a blank line removal tool first if you want to exclude them from the output.
Q: Is the sort stable? A: Yes, lines with equal sort keys keep their original relative order. For example, two lines of the same length will remain in their original sequence when sorting by length.
Q: What does "shuffle" do? A: Shuffle randomizes the order of lines using the Fisher-Yates algorithm, producing a fair unbiased random order. Each click gives a different result.
Q: What happens with numbers that have decimals? A: The numerical sort parses each line as a floating-point number, so values like 3.14 or -0.5 are handled correctly.
Q: Does case sensitivity affect numerical sorting? A: No. The case sensitive toggle only affects alphabetical sorts. Numerical and length-based sorts are unaffected by case.
Q: Can I sort lines that contain commas, tabs, or other delimiters? A: Yes. The tool sorts whole lines regardless of their content. Each newline character defines where one line ends and the next begins.
Q: Is my data stored or sent anywhere? A: No. All sorting happens locally in your browser. Your text is never transmitted to any server.
