Convert Text to HTML List (revised)

Return to ClipboardFusion Macros

Description	Converts the copied text into a HTML list. This Macro takes each line of the copied text and turns it into a HTML list item, then puts them into a HTML ordered or unordered list. This revised version uses spaces instead of tabs, and supports a detection of a few other list types.
