Jackson is the de facto standard JSON parsing and data-binding library for Java and the JVM, providing a streaming parser/generator, POJO-to-JSON databinding, and modules for formats like YAML, CSV, CBOR, and Avro. It is a mature, actively maintained multi-module project with recent Jackson 3.x releases.

Use cases

• serialize and deserialize JSON in Java
• convert POJOs to and from JSON
• parse large JSON files with streaming
• read and write YAML, CSV, or CBOR on the JVM
• bind JSON to Kotlin data classes
• consume and produce JSON in REST APIs

When to choose

• you need JSON processing on the JVM with maximum ecosystem compatibility
• you want high-performance streaming parsing of large documents
• you need support for multiple data formats beyond JSON
• you want a battle-tested, widely adopted serialization library

When to avoid

• you need JSON processing in a non-JVM language
• you want a minimal zero-dependency JSON parser for simple use cases
• you need schema validation as a first-class feature (use dedicated validators)
