Popular line sorting tasks
Sort mode reference
| Mode | Behavior | Best for |
|---|---|---|
| Natural | Locale-aware text order with embedded numbers treated numerically | Files, IDs, versions, item2 versus item10 |
| Alphabetic | Locale-aware text comparison without numeric grouping | Names, keywords, tags, labels |
| Numeric | Sorts by the first localized number, including decimals and exponents | Scores, prices, numbered exports |
| Length | Counts Unicode grapheme clusters rather than UTF-16 units | Short or long entries, emoji and accented text |
| Random | Uses a Fisher-Yates shuffle with browser cryptographic randomness | Randomized lists, samples and prompts |
Line sorter notes
Private local processingSorting, deduplication, preview, and download happen in your browser. Nothing is uploaded.
Natural orderingNatural mode places file2 before file10 and uses the selected locale for letters and accents.
Localized numeric modeNumeric mode reads the first number using the selected locale's decimal and grouping symbols. Lines without numbers remain after numeric lines.
Unicode-aware cleanupNFC matches canonically equivalent accents; NFKC also matches compatibility forms. Length mode counts visible graphemes.
FAQ
Does this tool upload my list?
No. Sorting and all related processing happen locally in your browser.
What is natural sorting?
Natural sorting treats embedded digits as numbers, so item2 appears before item10.
Can numeric mode read decimals and scientific notation?
Yes. It reads the first localized number on each line, including signed decimals and exponents such as 1e3.
How are emoji and accented characters handled?
Locale-aware comparison handles letters and accents, while length mode counts user-visible Unicode graphemes rather than code units.
