使用方法
- Paste a list of lines into the input area — one item per line。
- Choose a sort order: alphabetical, reverse alphabetical, by line length, or numeric。
- Toggle deduplication to remove duplicate lines, with optional case-sensitive matching。
- Enable trim and remove-empty-lines options to clean up whitespace。
- Copy the output or use the copy-link button to share the state — everything runs in your browser。
範例
- Pasting 10 country names with 3 duplicates, enabling sort A→Z and dedupe, reduces the list to 7 unique names in alphabetical order。
- Pasting a mixed list of numbers like "10\n2\n20\n1" and choosing numeric sort produces "1\n2\n10\n20" instead of lexicographic order。
