Eq2LayoutEditor

Everquest II House Layout Editor is a free game editor.
To use this program you will need to have Microsoft .Net version 3.5 or higher.
This application allows you create groups.

Groups work entirely off of UIDs. It is important to note that UIDs are changed if you pick up an item in game.
Also from the main menu you can access the tab "Diff". When clicking the button the editor will reparse the currently loaded file and parse the selected file. The editor will then create a list of any item in the currently loaded file that does not have an exact match in the selected file.
Another function is Auto Replace. When using Auto Replace, the editor will look in the crate for an item with a matching ItemID.
