Read

If you have json file like the following :

{
	"Weapon": "fangs",
	"LifePoints": 1000,
	"Speed": 3.14,
	"Enemy": false,
	"GoldPerItem": [1, 2, 3],
	"Ability":
	{
		"Attack": 20,
		"SpecialAttack": 40 
	}
}

you can get the values this way

json["Weapon"].getValue<std::string>();				//"fangs"
json["LifePoints"].getValue<int>();				// 1000
json["Speed"].getValue<float>();				// 3.14
json["Enemy"].getValue<bool>();					// 0 (false)
json["GoldPerItem"][0].getValue<int>();				// 1
json["GoldPerItem"][1].getValue<int>();				// 2
json["GoldPerItem"][2].getValue<int>();				// 3
json["Ability"]["Attack"].getValue<int>();			// 20
json["Ability"]["SpecialAttack"].getValue<int>();		// 40

Save

To save json

if (json.save("FilenameWhereYouWantToSave.fileExtension"))
{
   // File was successfully saved.     
}

If you have written this information

SJR json;
json["Planet"].setValue<std::string>("Earth");
json["Radius"].setValue<double>(6.371);

json.save("FilenameWhereYouWantToSave.fileExtension");

You will get the file

{
    "Planet" : "Earth",
    "Radius" : 6.371
}
