Sort Text Lines Alphabetically Online
Sort text lines alphabetically, by length, numerically, randomly, or in reverse — all in your browser, with no setup. Paste a list into the input and the sorted result updates the moment you make a change, so there is no button to hunt for.
This line sorter is built for anyone who works with lists: developers tidying config files and imports, writers alphabetizing keywords, data folks deduplicating entries, teachers building vocabulary lists, and organizers shuffling names for a draw. Each line is treated as one item, and you can trim whitespace, drop blank lines, and remove duplicates as part of the same pass.
How to Sort Your Lines
Add your text
Type into the Input panel or hit Paste to pull text from your clipboard. Each line counts as one item to sort.
Pick a sort mode
Open the Sort dropdown and choose A → Z, Z → A, Numeric 1 → 9, Numeric 9 → 1, Short → Long, Long → Short, Random, or Reverse.
Tune the options
Set Case to Sensitive or Insensitive, then toggle Trim, No Empty, and Unique to clean the list while you sort it.
Copy or download
The sorted lines appear in the Output panel instantly. Use Copy for the clipboard or Download to save a sorted-lines.txt file, and check Total, Result, and Removed counts as you go.
Features
Real-Time Processing
Lines re-sort the instant you type, paste, or change an option — no apply button, smooth even with large lists.
Multiple Sort Modes
Eight modes: A→Z, Z→A, numeric ascending and descending, by length both ways, random shuffle, and a plain reverse.
Natural Numeric Sort
Reads the first number in each line so 2 lands before 10 instead of being sorted as plain text.
Case Sensitivity Control
Switch between Sensitive sorting for code and technical data, or Insensitive to treat "Apple" and "apple" alike.
Whitespace Trimming
Strip leading and trailing spaces from each line before sorting for consistent results across messy sources.
Empty Line Removal
Turn on No Empty to drop blank lines, leaving a clean list ready to import elsewhere.
Duplicate Removal
The Unique option drops repeated lines while sorting, and respects your case setting when matching duplicates.
Live Statistics
A counter shows Total input lines, Result lines, and how many were Removed by empties and duplicates.
Synced Line Numbers
Input and output panels show line numbers that scroll in sync, making it easy to spot-check the order.
Export & Shortcuts
One-click Copy and Download to a .txt file, plus Ctrl+Shift+C to copy and Ctrl+Shift+X to clear.
Preference Persistence
Your sort mode, case setting, and option toggles are saved in your browser and restored on your next visit.
Fully Private
All sorting runs locally in the browser, so nothing you paste ever leaves your device.
Frequently Asked Questions
How do I sort text lines alphabetically online?
Paste your text into the Input panel, then pick A → Z from the Sort dropdown for ascending order or Z → A for descending. The sorted result appears in the Output panel right away — there is nothing to install or sign up for.
Can I sort lines by length?
Yes. Choose Short → Long to put the shortest lines first or Long → Short to lead with the longest. Length sorting counts the characters in each line, which is a fast way to find the shortest or longest entries in a list.
What's the difference between A→Z and Numeric sort?
A → Z compares lines as text, so "10" lands before "2" because the character "1" is less than "2". Numeric sort reads the first number in each line and compares the actual values, so 2 correctly comes before 10. Use Numeric for version numbers, quantities, and numbered items. Lines with no number are treated as 0.
How do I reverse the sort order (Z–A)?
For reverse alphabetical, pick Z → A. If instead you want to flip the existing order of a list without sorting it, choose Reverse — the last line becomes first while the relative positions are preserved.
Does it remove duplicate lines while sorting?
Yes. Turn on the Unique option to drop repeated lines in the same pass. Combine it with Case set to Insensitive to treat "Hello" and "hello" as the same line — no separate deduplication step needed.
How does the Random shuffle work?
The Random mode uses the Fisher-Yates shuffle for an even, unbiased order. Lines reshuffle each time you make a change, so it suits draws, random selection, or any case that needs fair randomization.
Can I combine the options?
All options work together. For example: A → Z + Case Insensitive + Unique gives an alphabetized list of unique items ignoring case; Short → Long + Trim + No Empty surfaces your shortest content after cleaning whitespace and blanks; Numeric + Unique returns unique numbers in numerical order.
Is there a line or character limit?
There is no fixed limit. Because everything runs in your browser, the practical ceiling depends on your device's memory — most modern browsers handle hundreds of thousands of lines without trouble.
Is the text processed in my browser (private)?
Yes. All sorting happens locally in your browser with JavaScript. Your text is never uploaded or transmitted, which makes the tool safe for sensitive or confidential lists. Only your option preferences are stored, and they stay in your browser.
Are there keyboard shortcuts?
Yes. Press Ctrl+Shift+C to copy the output and Ctrl+Shift+X to clear the input and output. You can also paste with the usual Ctrl+V inside the input panel.
