What is JSON file format?
JSON (JavaScript Object Notation, pronounced /ˈdʒeɪsən/; also /ˈdʒeɪˌsɒn/) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values).
What is the structure of a JSON file?
JSON defines only two data structures: objects and arrays. An object is a set of name-value pairs, and an array is a list of values. JSON defines seven value types: string, number, object, array, true, false, and null. The following example shows JSON data for a sample object that contains name-value pairs.

Can JSON array have different types?
In JSON, each element in an array may be of a different type. In Python, “array” is analogous to a list or tuple type, depending on usage. However, the json module in the Python standard library will always use Python lists to represent JSON arrays.
