Text Joiner
Join multi-line lists into one delimited string in one click — perfect for CSV strings, regex alternations and JSON arrays.
What is Text Joiner?
You have a list of values one per line and need them as one string with specific punctuation. Maybe pipes for regex, commas for CSV, or quoted values for a JSON array.
Paste your list, pick separator and wrappers, and get the joined string back.
If you're building Excel formulas, you produce single-string inputs. If you're wiring no-code workflows, you flatten arrays for legacy fields. If you're crafting regex, you build clean alternations.

Common questions
