How it works
The input is split on newlines to produce an array of lines. Trim whitespace applies String.trim() to each line. Remove duplicates uses a Set keyed on the lowercased line to preserve the first occurrence. Sort modes use Array.sort() with localeCompare() for alphabetical ordering or a length comparison for length-based modes. Shuffle uses the Fisher-Yates algorithm with Math.random(). The result array is joined back with newlines. All processing runs in JavaScript in your browser.

For swapping recurring substrings across the list, try find and replace. To compare two sorted lists side by side, use text diff. For checking item counts after deduplication, see the word counter.
Frequently asked questions
- How does alphabetical sorting work?
- Lines are sorted using the browser's locale comparison with case-insensitive matching, so capitalisation does not affect the order. The sort is stable: lines with equal values keep their original relative order.
- Does it sort case-sensitively?
- No. Both the A–Z and Z–A sorts are case-insensitive, so 'Apple' and 'apple' are treated as equal and grouped together regardless of their capitalisation.
- Can I sort a list with numbers?
- Yes. Numeric strings sort lexicographically by default (so '10' comes before '9'). For natural number sorting where '9' comes before '10', use the length sort modes which handle numeric strings more intuitively.
