Lines into a single list
Got a column of values you need on one line — for a SQL IN (…) clause, a CSV cell, or a config array? This joins each line with the separator you choose, with options to trim stray spaces, drop blank and duplicate entries, and wrap each value in quotes for code. The reverse tool splits a list back into lines. Everything runs locally in your browser.
