JSON

JavaScript Object Notation (JSON) is a lightweight data-interchange format.https://www.json.org
In Minecraft, JSON format is used to store the following data:
* Text in written books, signs, custom names and the , , , and commands.
* The pack.mcmeta file that describes a resource pack and data pack.
* The manifest.json file that describes a add-on.
* Files in a resource pack that define models, sound events, UI, etc.
* Files in a behavior pack that define entity behaviors, block behaviors, item behaviors, etc.
* Advancements and statistics (as .minecraft/saves/*/data/stats/*.json)
* The profile data for the launcher (as .minecraft/launcher_profiles.json)
* Information about downloaded versions (as .minecraft/versions/*/*.json)
* Files in a data pack that define advancements, loot tables, tags, recipes, dimensions, dimension types and predicates.
== Syntax ==
=== Data types ===
A JSON file must contain a single JSON value, which can use any of the following five data types: string, number, object, array, and boolean.
JSON files can be contained in a single line, however it is often useful to use indentation and line breaks to make a long JSON file more readable.
==== String ====
A string is delimited by quotes and can contain any combination of characters. Some special characters need to be escaped; this is done with a back slash (\).
* 
* 
* 
==== Number ====
A number is defined by entering in any number. Numbers can be non-whole, as indicated with a period, and can use exponents with e.
* 
* 
* (=3×106)
==== Object ====
An object, also referred to as a compound, is delimited by opening and closing curly brackets and contains key/value pairs. Pairs are separated with commas, keys and associated values are separated with colons. Each contained key needs to have a name that is unique within the object. A value can be of any data type as well (including another object).
{
 "Bob": {
 "ID": 1234,
 "lastName": "Ramsay"
 },
 "Alice": {
 "ID": 2345,
 "lastName": "Berg"
 }
}
==== Array ====
Arrays are delimited by opening and closing square brackets and can contain values of any data type, separated by commas. Unlike lists in NBT, values in a JSON array can use different data types.
["Bob", "Alice", "Carlos", "Eve"]
==== Boolean ====
A Boolean can be either true or false.
{
 "Steve": {
 "isAlive": true
 },
 "Alex": {
 "isAlive": false
 }
}
