Join lines
Turn a multiline list into one text value using your own literal delimiter, with optional trimming and blank-line removal.
How it works & useful details
How to use this tool
Paste one item per line and enter the characters to place between items. An empty delimiter concatenates items directly.
How the result is calculated
The delimiter is literal: typing backslash followed by n inserts those two characters, not a newline. This does not quote or escape CSV fields; use a CSV tool for data containing commas or quotes. Skip blank lines also skips whitespace-only lines.
Line tools normalize CRLF and CR to LF. A final newline represents an empty final line; empty input has zero lines.
Up to 500,000 UTF-16 code units per input. Text stays on your device.
The result is limited to 2,000,000 UTF-16 code units.
