{"key1": value1, "key2": value2, ... "keyn": "valuen"}

List

[item1, item2, ... itemn]

How to find the JSON file of a project

Simply put this in the URL bar of your browser: http://projects.scratch.mit.edu/internalapi/project/PROJECTID/get/ and replace "PROJECTID" with the id of the project to get the JSON file of.

For instance, if one would want to get the JSON file of a project with the url "https://scratch.mit.edu/projects/123456789/" they would replace "PROJECTID" with "123456789" resulting in "http://projects.scratch.mit.edu/internalapi/project/123456789/get/"
