Merge several lists into one
Paste two or more lists and get one list back, in the order you choose: as pasted, sorted, or with duplicates removed first. Handy for collecting several keyword or ASIN lists into a single one before comparing them.

How merging works
Can I merge more than three lists?
Paste any additional lists into one of the three boxes, one after another. Each box holds as many lines as you like.
What order does the result come in?
List 1 first, then list 2, then list 3, unless you tick “Sort A–Z”. With duplicates removed, the first occurrence wins.
