Jansson is a C library for encoding, decoding, and manipulating JSON data. It offers a simple API, full UTF-8 Unicode support, and no dependencies on other libraries.

Use cases

  • parse json in c
  • encode json from c program
  • decode json files in c
  • manipulate json data structures in c
  • embed json support in embedded c project
  • serialize data to json in c

When to choose

  • you need a lightweight, dependency-free JSON library for C
  • you want full Unicode/UTF-8 support
  • you need a well-documented, extensively tested JSON parser
  • you target multiple platforms including Android

When to avoid

  • you are working in C++ and prefer a native C++ JSON library
  • you need JSON schema validation or JSONPath queries
  • you want a header-only library
