What SortLines does
SortLines helps with common line-based tasks: sorting lines, removing duplicates, removing empty lines, comparing two lists, finding duplicates, randomizing lists, reversing line order, and cleaning keyword lists.
Who it is for
The tools are designed for SEO work, spreadsheets, developer tasks, operations lists, email exports, URL lists, and any workflow where one item per line is easier to edit than a full spreadsheet.
How it works
The tools run in your browser. Paste text, choose the action, then copy or download the result. The site is intentionally lightweight so it can load quickly on desktop and mobile.
