What is Serialize and Deserialize for? [duplicate]

With Serialize, you create a series of data, for example a JSON.

You can serialize a List list in a JSON to return to a page and fill a grid of data via javascript, for example.

The same happens on the contrary, you "deserialize" a JSON to a list List

Serialize is the process of transforming an object into a stream of bytes! An example is to get a List < > and turn it into a JSON to manipulate somewhere and then turn it into a List again.
