There are several ways to export data from the Compensation depending on the export required.  For detailed explanation for each type of export please view the appropriate support topic.

On each page that exports are available you will see a red "EXPORT" link  at the top right hand of the page.  Click the Export link and the page will display the exports that are available.

Additionally you have access to all your exports from the the Project Management section in the "Create Project Export" section of the page.
