(Documentation in English)
What it does
Sort, dedupe, reverse, shuffle, or length-sort the lines of any text. Supports case-insensitive and natural sorting (so file2 comes before file10). 100% client-side — your text never leaves the browser.
How to use it
- Paste text into Input (one item per line), or tap a Try: sample chip above the mode switch.
- Pick a mode. The result updates live on the right.
- Toggle the options you need.
- Copy the result or Download it as
sorted.txt.
Modes
| Mode | What it does |
|---|---|
| A→Z | Alphabetical, ascending |
| Z→A | Alphabetical, descending |
| Short | Shortest lines first (ties keep their original order) |
| Long | Longest lines first (ties keep their original order) |
| Reverse | Mirrors the current line order — no sorting |
| Shuffle | Deterministic random order (seeded, see below) |
| Unique | Removes duplicate lines, keeping the first occurrence of each. Order is preserved — Unique does not sort |
Options
- Case sensitive — off by default, so
Appleandapplecompare as equal and interleave freely. Turn it on to sort uppercase and lowercase strictly apart. - Natural sort — off by default. On, embedded numbers sort by value instead of digit-by-digit, so
file2precedesfile10. Applies to A→Z and Z→A only.
The result header shows the live line count, plus the removed-duplicate count when Unique is active. Download appears only when there is output to save.
Examples
All outputs below are verified against the tool’s actual behavior.
A→Z (default, case-insensitive) — original casing is preserved, only the order changes:
banana
apple
Cherry
apple
Date→
apple
apple
banana
Cherry
DateCase sensitive on (input: banana, Apple, cherry, apple, Banana):
- Off →
Apple,apple,banana,Banana,cherry - On →
apple,Apple,banana,Banana,cherry
Natural sort (input: file10, file2, file1):
- Off →
file1,file10,file2 - On →
file1,file2,file10
Unique (input: readme.md, src/, readme.md, tests/, src/, readme.md) → readme.md, src/, tests/ — 3 lines, 3 duplicates removed, first-occurrence order kept.
Short (fruit sample above) → Date, apple, apple, banana, Cherry — lengths 4, 5, 5, 6, 6 with ties keeping their original order.
Good to know
- Private: all processing is local.
- Unique keeps the first occurrence of each line (case-insensitively matched by default) and preserves order — it never sorts. Combine it by first using A→Z, then Unique.
- Shuffle is seeded, so the same input gives the same order every visit (the fruit sample shuffles to
Date,Cherry,apple,banana,apple). - Clearing the input empties the result and hides the download button.
