# Parameter Manager
With this tool, users can create new project parameters and/or edit family parameters (e.g. convert parameters from instance to type-based, import many shared parameters at once, etc.).
In a project file, the user can import one or more shared parameters and apply them to multiple categories at once in a selected group.
In a family file, user can manage several parameter properties at once. Additionally, it is possible to change parameters from instance to type, delete, and import one or more shared parameters from the shared parameter file. The tool enables user to export parameters to a JSON file which can be imported to a different family file with the same parameters and definitions.

The Parameter Manager dialog box allows users to convert Revit Family Parameters from one type to another (e.g. convert parameters from instance to type-based), Import / Export many Shared Parameters at once, or Remove selected Parameters.
Select Parameters by checking the boxes in front of them. Use the toolbar to:

# Tips and Tricks: Transfer Shared Parameters from one Revit Family to multiple families
Read blog article (opens new window) with an example on how to transfer Shared Parameters from one Revit Family to multiple families
Export Shared Parameters into JSON file
Open a Family from which you want to export Shared Parameters from. Go to the Content Admin Kit tab and open Parameter Manager.
Select the parameters you would like to export into a JSON file and click Export.
Define a path and a File name.
Apply Exported Shared Parameters to multiple families at once
Go to the Content Admin Kit tab and select Update Category 
.
Update Family Category dialog box opens up. Under Data press (three dots) and select the folder in which you have all the families that you want to update. Under Import, JSON Definition select 
(three dots) to select the JSON file you exported earlier. Select OK.
All the Families in the selected folder will get updated and will now include the applied shared parameters.
