YAJL (Yet Another JSON Library) is a small, portable ANSI C library for parsing and generating JSON using a streaming, callback-based (SAX-style) model. It is data-representation independent, fast, memory-efficient, and provides verbose error messages with input context.

Use cases

• parse large JSON files without loading them fully into memory
• incrementally parse JSON from a network stream
• build a custom in-memory JSON representation in C
• write a JSON filter or converter tool like a pretty printer
• embed a fast robust JSON parser in a C or C++ application
• convert JSON to another format such as XML

When to choose

• you need streaming/incremental JSON parsing in C
• you want control over the in-memory data representation
• minimal CPU and memory footprint matters
• you need a permissively licensed, portable ANSI C JSON library

When to avoid

• you want a ready-made DOM/tree API out of the box
• you are working in a higher-level language with native JSON support
• you need JSON Schema validation or JSONPath queries
