CodeLiner is an Excel (and Word) toolbar in the VBA Editor that will add and remove code line numbers with one click. Code line numbers are important because they let you discover the exact location of an error (The Office built-in function, Erl(), will not return a line number unless code line numbers have been added to the VBA Project). CodeLiner also cleans up code line numbers on-demand when you need an unobstructed view of your code.
A simple toolbar with buttons to toggle line numbers on and off. An easy-to-use and easy-to-install targeted solution to a common Office VBA problem when trying to debug code.
