The SharePoint PageCloner is a utility for automatically creating multiple duplicates of a "template" web part page that you have layouted and pre-populated with web parts and web part settings once.
The Problem:
Manually copying web part pages (*.aspx) does not cover the web parts placed on the source page. Manually exporting and importing those web parts is time-consuming and not available for list or library web parts.
The Goal:
You want to create in one go many copies of a "template" / "master" web part page that you have layouted and pre-populated with web part instances and web part settings.
The web parts require certain customizations for each copy of the web part page, but always in a similar fashion.
The Solution:
The SharePoint PageCloner utility is fully configurable and parameterizable and allows for one-off source page customizations to be applied to all cloned target pages.
