I want to know how to turn a .json file into a .sb3 file, and vice versa on a chromebook. Thanks

(I didn't know if I could do it but I made this topic in the wrong topic section so I put it in the right one-)

If that JSON file is a project.json, you can just go to File -> Load from your computer in the online editor, select “All files” in the file selector (renaming the project.json file to an .sb3 file might work too) then select it. It will load that project.json, and assets will be loaded from Scratch's servers (or replaced with a gray question mark/empty sound if they aren't on the servers, as project.json files doesn't contain the whole asset). Then you can File -> Save to your computer if you want an .sb3 back.
Though that will also clear the project's name, so you'll have to reenter the name.

So basically I has the same issue, I made a game on scratch but a problem with the filesize said that I couldn't save it so I importeted into turbowarp and then exported it because apparently it reduces and helps with filesize problems. it saved as a json and when I try to make it into and sb3 by either doing all files or renaming it, it says scratch could not open that file -__-

1. make a blank project 2. save it 3. convert to zip 4. unzip 5. replace json code with your json 6. rezip 7. load

To turn a .json into a .sb3, you can literally rename its file extension to .sb3 and upload it (having tested this recently, this does work).

To get the project.json from a downloaded .sb3, unzip it (you can rename its extension to .zip, if you need to) and open the project.json file inside.
