# Properties & Charts

Once a project is exported to Web App, the corresponding JSON is retrieved from the service and saved in the Revit project file using Revit Extensible Storage. Later it could be viewed in user-friendly format using the **Properties & charts** command.

To open it, click the corresponding item in the **bimCAT** drop-down menu.
