Natural vs Pure Lexicographical Sorting
Standard alphabetical sorting arranges 'item10' before 'item2'. Enabling Natural Sort parses embedded numeric sequences as whole integers, correctly ordering 'item1', 'item2', and 'item10'.
Negative and Decimal Floating-Point Numbers
When using Numeric Value sort, lines containing negative numbers (e.g., -5) and decimals (e.g., 3.14) are parsed according to standard arithmetic magnitude rather than character codes.
Case-Insensitive Deduplication
By default, duplicate removal considers 'Item' and 'item' as identical duplicates. Toggle Case Sensitive to preserve distinctions between mixed capitalization lines.
How it works
- Splits input text into discrete line segments, normalizing Unix (\n) and Windows (\r\n) line separators.
- Applies selected transformation: Intl.Collator natural ordering, numerical parsing, line length comparison, or hash-set deduplication.
- Reconstructs output using standard line breaks while maintaining memory-efficient processing.
- Executes entirely client-side inside an isolated Web Worker without server network communication.

Frequently asked questions
What is natural sort order?
Natural sort orders strings in human-friendly order by treating multi-digit numbers as single numeric values rather than comparing character by character (e.g., File 2 comes before File 10).
Does deduplication change the order of unique lines?
No. The Deduplicate Lines operation preserves the original order of items as they first appeared in your list.
Are my lists or sensitive documents uploaded anywhere?
No. All sorting, deduplication, and shuffling executes 100% locally in your web browser. No data ever leaves your device.
