JSON Storage Format

Jul 03 2018, 9:40 AM PST 2 min

JSON is a data storage format.

HttpService provides two functions for working with JSON data:

HttpService/JSONEncode, which converts a variable to its JSON equivalent
HttpService/JSONDecode, which converts a JSON value to its Lua representation

JSONEncode cannot encode anything other than strings, numbers, tables, and booleans - passing anything else to it will error.

Encoding

This code snippet encodes characterStats into a JSON string and prints it to the output.

			local HttpService = game:GetService("HttpService")

local characterStats = {
	money = 123456;
	title = "1337 h4x04";
	is_epic = true;
	awards = {
		kills10 = true;
		died20 = false;
	};
}

local json = HttpService:JSONEncode(characterStats)
print(json)
		
			{"awards":{"died20":false,"kills10":true},"title":"1337 h4x04","is_epic":true,"money":123456}
