What is JSON deserialization?

JSON deserialization converts JSON data into programming objects such as classes, structs, or data models.

Why do backend services deserialize JSON?

Deserialization allows applications to process structured data safely by converting external API payloads into typed objects.

Most programming languages support JSON deserialization through libraries, including Java, Go, Rust, Python, JavaScript, and C#.

Deserialization is safe when proper validation is implemented. APIs should always validate input data and enforce schemas before processing requests.
