The ability to import and export a JSON file is a useful feature built into Design Palette Pro.  

What's a JSON file? 

Without getting overly technical, the JSON file contains all the settings you have saved in Design Palette Pro.

   Updating your site, or making changes to Design Palette Pro?

Use the Data Export function before making changes to download the existing customizations to a JSON file on your computer. If you don’t like the changes made, or there is a glitch with an update, you can use the Data Import feature to upload the JSON file to restore the Design Palette Pro settings.

The JSON file is also handy for when you have more than one website using the same child theme, and you want to copy over the same Design Palette Pro settings from one to the other.
