How it works
Paste a list, one item per line, and choose how to transform it. You can sort alphabetically (A→Z or Z→A), numerically, or by line length, reverse the order, remove duplicate lines, trim whitespace from each line, and drop empty lines. The operations run in your browser using native sorting and a set for de-duplication, and the result updates live. It is handy for cleaning up word lists, email lists, or any column pasted from a spreadsheet. Nothing is uploaded.
Common use cases
- Alphabetizing a list of names or terms.
- Removing duplicate entries from a pasted email or keyword list.
- Sorting a column of numbers or sizes pasted from a spreadsheet.
Frequently asked questions
How does numeric sorting differ from alphabetical?
Alphabetical sorting compares text character by character, so "10" comes before "2". Numeric sorting reads each line as a number, so 2 correctly comes before 10. Choose numeric for lists of numbers.
Does removing duplicates keep the first occurrence?
Yes. De-duplication preserves the first time each line appears and drops later identical lines, so the original order of unique items is kept unless you also apply a sort.
Is my list uploaded anywhere?
No. Sorting and de-duplication happen entirely in your browser, so your list never leaves your device.
