A way to get entire list of instance class names?

What I want to do is:
Get every instance class name inside:
image
Any scripts will help!

Can you specify what you want? I couldn’t understand what you mean by that.

Thanks.

Good question, you can’t in the actual api, but here’s something made by another developer for this specific reason. GitHub - MaximumADHD/Roblox-API-Dump-Tool: A tool that lets you view and compare the latest API Dump files from Roblox's servers.

What I mean is, basically You know class names? I want to get all of class names.
