This is the detailed documentation of every class and function of the ArduinoJson library. Some parts have been simplified to be easier to understand, so if you look at the source code, you might see some differences.

Entities

JsonArray

Stores an array of JsonVariant

JsonObject

Stores a collection of key-value pair where each key is a string and each value is a JsonVariant

JsonVariant

Stores any kind of value allowed in a JSON document: int, float, array, object…

Utilities

JsonBuffer
