cJSON is an ultralightweight JSON parser and serializer written in ANSI C, distributed as a single C file and header. It provides simple parsing and printing of JSON data structures with minimal dependencies.
Use cases
- parse json in c
- serialize data to json from embedded device
- lightweight json library for microcontroller
- read json config file in c program
- generate json output from c application
- embed json support in firmware
When to choose
- you need JSON support in C or C++ with minimal footprint
- targeting embedded or resource-constrained systems
- you want a dependency-free, easily vendored single-file library
When to avoid
- you need high-performance or standards-exhaustive JSON handling with strict edge-case compliance
- you need thread-safe parsing out of the box
- you're working in a higher-level language with native JSON support
