Merge lists

Merge lists

Merge Lists tool combines two or more lists into one, with options for separators, line breaks, or commas.

This tool provides an easy and quick way to merge two lists line by line. In this, a text can optionally be prefixed or appended to each list. This provides for example the possibility to produce a CSV compatible list from two lists. By repeating the process, you can also merge more than two lists.
