4. Once the JSON Data Bank holds a JSON object, you can go to the JSON tab in the Expected JSON panel and select any portion of the object. Once selected, you can click on the Add button in the center to extract the value during runtime. The keyword "this" in the JSON tab represents the object itself.
   The extracted properties will display in the right-hand table. When you double-click on the entry or click Modify, a dialog will display that allows for more extraction options.
   • Extraction: Allows you to select a different property to extract.
   • Data Source column name: Allows you to change the column name that this value will be mapped to. You can also choose to write the value to a Writable Data Source or variable.

Once you have everything set up in the JSON Data Bank, you can use the extracted value by switching a parameterizable field to Parameterized mode and selecting the column you want.
