Line sorter — alphabetical A–Z and Z–A, sort by length, or shuffle lines in the browser

Use this free online line sorter when you need a fast way to reorder pasted text line by line: alphabetically A–Z or Z–A with optional case-insensitive comparison, by line length (shortest or longest first), or in random order for quick shuffles of brainstorm lists and QA scenarios. Unlike spreadsheet sorts that need column import steps, this page treats each newline as a row—ideal for dependency lists, route tables, environment keys, package names, and log excerpts you copied from a terminal. Processing stays in your browser: upload a .txt file or paste directly, then copy the sorted block. Pair sorting with our duplicate line remover when you need unique rows after ordering, or the whitespace remover when invisible spaces break comparisons.

Sorted output

9 lines in → 9 lines out. Duplicates are kept; only order changes.

Why use a dedicated text line sorter?

Editors and terminals can sort, but a focused sort lines online workflow keeps you inside the browser when you are reviewing a paste from Slack, a CI artifact, or a vendor CSV you do not want to open in Excel. Alphabetical modes help you spot typos in long identifier lists; length-based sorting highlights unusually short or long rows before code review; random shuffle supports quick sampling and classroom demos. Because the tool preserves duplicate lines, you can mirror production data density and only dedupe later with the duplicate line remover when uniqueness matters.

Content and SEO teams often alphabetize keyword or URL lists before sharing; developers normalize import paths before diffing branches. After you sort two exports, paste them into the text diff checker to compare line-level changes without noisy order churn. For human-readable titles that will become URL segments, follow sorting with the slug generator and the text case converter.

How to use this line sorter (step by step)

  1. Paste content into the input area (one record per line) or click Upload .txt to load UTF-8 plain text. Use Load sample to see mixed casing and duplicate rows.
  2. Under Sort mode, pick A–Z, Z–A, shortest or longest line first, or random order. For alphabetical modes, toggle ignore case when uppercase and lowercase should sort together.
  3. In random mode, click Shuffle again after you edit the input so the permutation matches the latest lines.
  4. Use the copy control on the output panel to move sorted text into your editor, sheet, or ticket. If the browser blocks clipboard access, select the output and copy with Ctrl+C (Windows) or Cmd+C (macOS).

Keywords and workflows this page supports

People search for an alphabetical line sorter, sort lines by length online, reverse sort lines, or randomize line order when cleaning exports and prep lists for scripts. Data folks alphabetize column extracts before joining; SREs sort error tokens before deduping noisy tails. When you need delimiter-aware rows instead of raw lines, try the comma separator tool first, then return here for final ordering.

Sorting rules, stability, and empty lines

Alphabetical modes use Unicode-aware localeCompare with numeric sorting enabled so item10 orders after item2 when that reads more naturally. Length sorts break ties alphabetically. Blank lines participate like any other row. To strip or rewrite lines before sorting, combine with find and replace or the whitespace tool, then paste back here.

Privacy and practical limits

Sorting runs locally in your browser. Very large pastes may feel slower on older devices; for multi-megabyte logs, prefer streaming CLI tools. This UI targets chat-sized text, query results, and config snippets. For prose statistics rather than line order, use the word counter.

Frequently asked questions

What does the online line sorter do?
It splits your text into lines and reorders them. You can sort alphabetically A–Z or Z–A (with optional case-insensitive comparison), sort by line length shortest-first or longest-first, or shuffle lines into a random order. Duplicate lines are kept—this is not a deduplication tool. Everything runs in your browser.
Is my text uploaded to a server?
No. Pasted text and .txt files are processed with JavaScript in your tab. File upload uses the FileReader API locally; nothing is sent to our backend.
How does case-insensitive alphabetical sort work?
When enabled, A–Z and Z–A modes compare lines using Unicode case folding so uppercase and lowercase letters group together (for example, “apple” and “Apple” sort next to each other). The original spelling of each line is preserved in the output.
How are line endings handled?
The tool recognizes Windows (CRLF), classic Mac (CR), and Unix (LF) newlines when splitting. The output is joined with single newline characters, which most editors accept. Convert endings in your IDE if a toolchain requires CRLF only.
Why does random order not update as I type?
Random shuffle is intentionally stable while you edit so the list does not jump on every keystroke. After you change the input, use “Shuffle again” to re-randomize from the current text.
How is sorting by length different from alphabetical sort?
Length sorts order lines by character count (Unicode code units), using alphabetical order as a tie-breaker when two lines have the same length. Leading and trailing spaces count toward length unless you trim in another tool first.
Can I remove duplicate lines after sorting?
Yes. Use our duplicate line remover on the sorted output if you need unique rows while preserving whichever line the remover keeps as the first occurrence.
Which related text tools pair well with line sorting?
Normalize spacing with the whitespace remover, compare two sorted exports with the text diff checker, dedupe with the duplicate line remover, and convert between cases with the text case converter—all listed under Text & String Tools on the home page.
