If you want to build a tool that modifies Scratch projects automatically, you can use libraries designed to parse and repackage these files:
: You can use standard ZIP libraries to extract the project.json , modify the blocks or variables within the JSON, and then re-zip the contents back into a .sb3 format. 2. Version Control Features
An is actually a ZIP archive used by Scratch 3.0 to store project data, including code (in a project.json file) and media assets like sounds and images. sb3.zip
If your goal is to add a new functional block inside Scratch itself: You must develop a Scratch Extension using the Scratch VM.
Once compiled, the extension's data will be stored within the project.json whenever the user saves their project as an .sb3 . If you want to build a tool that

To develop a feature for a "sb3.zip" file, you usually need to interact with its internal components. Here are three common ways to approach this: 1. Programmatic Manipulation If your goal is to add a new
(e.g., an automated project editor, a file converter, or a new block within the Scratch interface?)
