The Visualizer is awesome and you can use it to create so many wonderful things, primarily, displaying your response data in a much more human consumable way would be the common use case but you can also use in to create tools to help certain workflows.
I’ve published a Visualizer template to help create and locally save JSON data files, these files can be used in the Collection Runner to add some variation to your data-driven testing.
This is the basic flow in action but I’m sure it could be used for other flows, given a flow modifications to the script.
You can grab a copy of the template here:
