About Line sorter
Sort newline-separated lines alphabetically, reverse, or numerically in your browser.
Sorting a list should not require a spreadsheet or a script you have to trust. Paste lines, pick ascending, descending, or a numeric interpretation, copy the result. Ordinary JavaScript string compare powers the alphabetical modes — locale quirks included.
Numeric mode helps when the lines are mostly numbers and you do not want '10' sorting before '2' as text. Mixed content still follows the mode you chose; garbage in remains garbage in.
Remove duplicates first on the duplicate-line tool if you need a unique sorted list. Case converter changes casing without sorting. Slug generator is for URL titles, not list order.

- Not a full Unicode collation customizer.
Common questions
Does line sorter use locale-aware sorting?
It uses ordinary JavaScript string comparison. For language-specific collation rules you may still want a dedicated locale tool.
How does numeric sort treat non-numbers?
Non-numeric lines are handled best-effort alongside parsed numbers. Clean the list if you need strict numeric-only order.
Can I sort by a CSV column?
No — whole lines only. Split columns elsewhere first if you need field-aware sorting.
