Free online random JSON data generator. Just press a button and get your random JSON structure. There are no intrusive ads, popups or nonsense, just a random JSON data creator. Press a button, get a random JSON. Created by developers from team Browserling.
This tool generates random JSON files. It lets you configure a ton of various randomizer options. You can set the generated JSON data structure's depth. Arrays and objects increase depth by one. You can set how many elemenents get generated per depth level. You can alo set if the generator should always use that many elements per depth level, or if it can choose to generate from 0 to max elements per depth level. Then this randomizer lets you choose allowed JSON data types. You can choose if you want to generate booleans, numbers, strings, arrays and objects. Then you can choose the source of string generation. It can be English words or it can be completely random characters.
This example generates random arrays of random booleans.
This example generates a flat array of 10 random strings.
This example generates a deep nested array structure that only holds a single element.
