I have 800+ projects (total shared and unshared), and I want to back them up, however, it would be very very time-consuming going into each and every project and downloading them.

Is there a way to download all projects?

No, but I know a faster way to download them all. It will require some keyboard usage, however. See the numbers in the links to the projects? Copy that, paste it into the URL bar, and add "https://projects.scratch.mit.edu/" Before the number. This will download your project in a small format, which saves time and space.

Not quite - for Scratch 3 projects and Scratch 2 projects that were created online, this will only download the project.json file (all of the code), which you can't really do anything with unless you also have the assets (sounds and costumes). (This will work for Scratch 2 projects created offline, and for Scratch 1 projects, but in those cases you still have to add the correct file extension manually.) see below posts

This tool by the creator of TurboWarp will allow you to more quickly download projects, just copy and paste the URL (note that nothing bad happens if you choose the wrong format, it just says that it's not available.).

It's very clear you probably didn't test this. You can open the JSON files in the editor, and it will work fine.

oh of course, the one test case that I didn't try is the one that actually works. (JSON in offline editor, JSON renamed to .sb3 in offline editor , JSON packed in .sb3 file in offline editor, JSON packed in .sb3 file in online editor, none worked.)

I would still recommend actually downloading the full project using the tool, since it's arguably more convenient and you don't need an internet connection to actually load the project.
