#### Decoding / Parsing
char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
StaticJsonBuffer<200> jsonBuffer;
```c++
char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
JsonObject& root = jsonBuffer.parseObject(json);
StaticJsonBuffer<200> jsonBuffer;
const char* sensor = root["sensor"];
long time = root["time"];
double latitude = root["data"][0];
double longitude = root["data"][1];
JsonObject& root = jsonBuffer.parseObject(json);
const char* sensor = root["sensor"];
long time = root["time"];
double latitude = root["data"][0];
double longitude = root["data"][1];

#### Encoding / Generating
StaticJsonBuffer<200> jsonBuffer;
JsonObject& root = jsonBuffer.createObject();
root["sensor"] = "gps";
root["time"] = 1351824120;
```c++
StaticJsonBuffer<200> jsonBuffer;
JsonArray& data = root.createNestedArray("data");
data.add(48.756080, 6); // 6 is the number of decimals to print
data.add(2.302038, 6); // if not specified, 2 digits are printed
JsonObject& root = jsonBuffer.createObject();
root["sensor"] = "gps";
root["time"] = 1351824120;
root.printTo(Serial);
// This prints:
// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
JsonArray& data = root.createNestedArray("data");
data.add(48.756080, 6); // 6 is the number of decimals to print
data.add(2.302038, 6); // if not specified, 2 digits are printed
root.printTo(Serial);
// This prints:
// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
