Lists pick up duplicates whenever they are merged, exported twice or copied from several places. This tool keeps the first copy of every line and drops the rest, while the counts tell you how many lines went in and how many came out.
Sort A to Z orders the result alphabetically without regard to capitals, with numbers in natural order, so item 2 comes before item 10.
This tool is built by ToolClack and, like everything we make, it is local-first: your data stays in your browser.
