What is Join Lines?
Combine many lines of text into a single line using the separator you choose. Optionally trim each line, skip empty lines and wrap each item in quotes — handy for turning lists into CSV, SQL IN-clauses or comma-separated values.
How Join Lines works
The tool splits your input on line breaks, optionally trims and filters the lines, then joins them with your chosen separator.
Example: three lines joined with ', ' become a, b, c; with quotes on, "a", "b", "c".
