# SMILE format
Smile is a computer data interchange format based on JSON. It can also be considered as a binary serialization of generic JSON data model, which means that tools that operate on JSON may be used with Smile as well, as long as proper encoder/decoder exists for tool to use.

// Parsing SMILE document
byte[] smile = " ... bytes of the SMILE document ... ";
Tree document = new Tree(smile, "smile");
// Getting / setting values
Date value = document.get("timestamp").asDate();
document.put("timestamp", new Date());
// Generating SMILE byte array from Tree
byte[] smile = document.toBinary("smile");
