TL;DR — paste lines, pick a mode, copy/download sorted output

Drop in any list and this online line sorter instantly sorts it: natural (number‑aware) or lexical A→Z, by length, or by a specific column. Choose case/accent handling, dedupe, manage blanks, and export in one click. Fully client‑side.

Sort Lines — natural, lexical, length, and column sorting (client‑side)

Clean lists in seconds with a flexible line sorter. Choose Natural (number‑aware), Lexical (pure A→Z), sort by Length, or sort by a Column (set delimiter and 0‑based index). Toggle ascending/descending, optionally reverse after sorting, make comparisons case‑ or accent‑insensitive, trim lines, deduplicate, and control how blank lines are handled. The sorted output updates immediately and stays private — everything runs in your browser.

How to use this line sorter

  1. Paste your list: add lines to Unsorted List, or load a .txt file.
  2. Choose a sort mode: Natural (number‑aware), Lexical, Length, or Column (set delimiter + column).
  3. Refine options: ascending/descending, reverse after sort, case/accent‑insensitive, trim lines, unique only, and blanks policy (drop/keep/top/bottom).
  4. Copy or download: grab the Sorted List or save it as .txt.

Key features

  • Natural (number‑aware) and Lexical A→Z sorting
  • Sort by length (short → long) or by a specific column
  • Ascending/descending with optional post‑sort reverse
  • Case‑insensitive and accent‑insensitive comparisons
  • Trim lines, handle blanks (drop/keep/top/bottom), and keep unique lines only
  • Instant results with copy and .txt download
  • 100% client‑side — private and fast

Tips

  • Use Natural sort for filenames or IDs with numbers (e.g., file2, file10).
  • Turn on accent‑insensitive to treat é≈e in multilingual lists.
  • Sorting by column works great for CSV/TSV: set delimiter and column index.
  • Deduplicate after trimming and case‑folding to collapse near‑duplicates cleanly.

Frequently asked questions

What’s the difference between Natural and Lexical sorting?
Natural is number‑aware (so img2 < img10). Lexical is strict character comparison (pure A→Z).
Can I sort by a specific column?
Yes—choose Column mode, set a delimiter (comma, tab, pipe, etc.), and provide the 0‑based column index to sort by.
How do blanks and duplicate lines work?
Pick a blanks policy (drop/keep/top/bottom) and enable Keep unique lines only to deduplicate after normalization.
What does accent‑insensitive mean?
It treats diacritics as equivalent for sorting (e.g., é ≈ e), which is helpful for multilingual lists.
Is my data uploaded anywhere?
No—everything runs locally in your browser; nothing is uploaded.
