What is the role of the process of transforming data from a serialized format back into an object state?

The process of converting data from a serialized format back into an object state is called deserialization. Its role is to restore objects from a saved or transmitted format (for example, JSON, XML, byte stream) so that the program can work with them as regular objects rather than raw data. This is important for data exchange between systems, saving state, and reusing objects.

Example in Python using the json module:

import json

json_data = '{"name": "Ivan", "age": 30}'
obj = json.loads(json_data)  # deserializing JSON into a Python dictionary
print(obj['name'])  # Ivan
