cJSON - Ultralightweight JSON Parser in ANSI C
cJSON is an ultralightweight, portable, single-file JSON parser and printer written in ANSI C, designed for simplicity and low memory usage.
Project Introduction
Summary
cJSON is a minimal JSON parser and printer implementation in C. It's intentionally kept simple and compact, making it ideal for embedded systems, command-line tools, or any project where a lightweight JSON solution is required without external dependencies.
Problem Solved
Existing JSON libraries in C were often complex, had significant dependencies, or were not highly portable. cJSON addresses this by providing a simple, single-file solution for basic JSON handling in pure ANSI C.
Core Features
Simple API
A straightforward and intuitive API for parsing, manipulating, and printing JSON.
Low Memory Footprint
Designed for minimal memory overhead, suitable for constrained environments.
High Portability
Written in ANSI C (C89), ensuring high portability across different platforms and compilers.
JSON Parsing
Includes robust functions for parsing JSON strings into a C data structure.
JSON Printing
Provides functions to render the C data structure back into a JSON string.
Tech Stack
