Besides that, you can get the json from arrays and dictionarys. Fill an array, or fill a dictionary. Store its json in the local storage.
I've found this plugin but I think that I don't need it. I can use the browser object with "invoke string"command to show the array in browser, but I need to get it as a file saved on my server. Do you know how I can do this?
