Sort lists alphabetically with advanced options for delimiters, case sensitivity, natural number ordering, and duplicate removal.

Alphabetical sorting is the process of arranging text items in order based on the sequence of letters in the alphabet. This fundamental organizational technique is used everywhere from library catalogs to contact lists, making information easier to find and navigate.
Modern sorting goes beyond simple A-Z ordering. Advanced algorithms can handle case sensitivity (where "Apple" and "apple" are treated differently), natural number sorting (where "file10.txt" comes after "file2.txt"), and international characters with proper locale-aware collation.
This tool uses the Intl.Collator API, which provides linguistically correct sorting that respects the rules of different languages and locales, ensuring accurate results for international text.
Choose between ascending (A→Z) or descending (Z→A) order.
Specify how your items are separated: new lines, commas, or tabs.
When enabled, numbers are sorted numerically (1, 2, 10) instead of alphabetically (1, 10, 2).
When enabled, uppercase and lowercase letters are treated as different (A ≠ a).
Automatically filters out duplicate entries from your list.
Natural Sort vs. Standard Sort:
Numbers sorted as text
Numbers sorted numerically
Natural sorting treats numbers within text as numeric values rather than individual characters. This means 'item2' comes before 'item10', which is more intuitive than alphabetical sorting where '10' would come before '2'.
When case sensitivity is enabled, uppercase and lowercase letters are treated as distinct. 'Apple' would be sorted separately from 'apple'. When disabled, they're treated as the same letter.
The tool supports three common delimiters: newlines (one item per line), commas (CSV-style), and tabs (TSV-style). Choose the one that matches your input format.
Duplicates are detected based on exact string matching. If case sensitivity is disabled, 'Apple' and 'apple' are considered duplicates. The first occurrence is kept, and subsequent duplicates are removed.
Yes! The tool uses Unicode-aware sorting that handles special characters, accented letters, and international alphabets correctly according to locale-specific collation rules.
No, case-insensitive sorting is the default. This means 'apple' and 'Apple' are treated as the same word. Enable case sensitivity if you need to distinguish between uppercase and lowercase.
Empty lines and whitespace-only items are automatically filtered out before sorting. If 'Remove Duplicates' is enabled, this happens after trimming whitespace from each item.
Yes! Enter your numbers (one per line or separated by your chosen delimiter) and enable 'Natural Number Sort' for proper numeric ordering. The tool will sort them correctly even if they're mixed with text.
