Open Source C JSON Software

The gSOAP toolkit is an extensive suite of portable C and C++ software to develop XML Web services with powerful type-safe XML data bindings. Easy-to-use code-generator tools allow you to directly integrate XML data in C and C++. Serializes native application data in XML. Includes WSDL/XSD schema binding and auto-coding tools, stub/skeleton compiler, Web server integration with Apache module and IIS extension, high-performance XML processing with schema validation, fast MIME/MTOM streaming, SOAP and REST Web API development, WS-* protocols (WS-Security, WS-Policy, WS-ReliableMessaging, etc), XML-RPC and JSON.

An ultra-lightweight, portable, single-file, simple-as-can-be ANSI-C compliant JSON parser, under MIT license. Moved to https://github.com/DaveGamble/cJSON

Jansson is a C library for encoding, decoding and manipulating JSON data.

HTTP Framework for REST Applications in C. Based on GNU libmicrohttpd for the backend web server, Jansson for the json manipulation library, and Libcurl for the SMTP client API. Used to facilitate the creation of web applications in C programs with a small memory footprint, as in embedded systems applications. You can create web services in HTTP or HTTPS mode, stream data, or implement server web sockets.

This JSON parser was created for the project of C++ Workflow.

pmacct is a small set of multi-purpose passive network monitoring tools. It can account for, classify, aggregate, replicate, and export forwarding-plane data, ie. IPv4 and IPv6 traffic; collect and correlate control-plane data via BGP and BMP; collect and correlate RPKI data; collect infrastructure data via Streaming Telemetry. Each component works both as a standalone daemon and as a thread of execution for correlation purposes (ie. enriching NetFlow with BGP data).

JSON parser is a highly efficient JSON data decoder written in C, that parses JSON data into a form that is very easy to use from within C code. You only need to include the json-parser.h file in your source code. If your project does not already incorporate D-List, you will also need to include dlist.h The JSON parser package also includes a JSON validator that does not parse or create resources, but allows the caller to validate JSON data from unknown sources, prior to any parsing attempts. The JSON data is returned to the caller as a set of hierarchical D-List list objects, that make the data very easy to manage, sort, search or use, and easy to remove when done. Package includes a JSON textural generator which will create JSON grammar data blocks from hierarchical D-List representations of JSON data. The package also includes a variety of support functions to allow C code to easily find, add, and modify JSON values and members in D-List hierarchical structures.

M's JSON parser is a small JSON parser written in ISO C which enables the user to handle information described by the JSON data interchange format.

Tpl makes it easy to serialize your C data using just a handful of API functions. The data is stored in its native binary form for maximum efficiency. C, Perl and XML supported. Data is portable across CPU types and OS's from Unix to Mac to Windows.

The project is an equivalent of a well known systems administration tool "cfengine". The aim of the project is to provide a safer and extensible framework for distributed system configuration management, using standard tools only.

flatcc has no external dependencies except for build and compiler tools, and the C runtime library. With concurrent Ninja builds, a small client project can build flatcc with libraries, generate schema code, link the project and execute a test case in a few seconds, produce binaries between 15K and 60K, read small buffers in 30ns, build FlatBuffers in about 600ns, and with a larger executable also handle optional json parsing or printing in less than 2 us for a 10 field mixed type message. The JSON parser may change the interface for parsing union vectors in a future release which requires code generation to match library versions. This project builds flatcc, a compiler that generates FlatBuffers code for C given a FlatBuffer schema file. This introduction also creates a separate test project with the traditional monster example, here in a C version. The setup script builds flatcc using CMake, then creates a test project directory with the monster example.

JsQuery is a language to query jsonb data type, introduced in PostgreSQL release 9.4. It's primary goal is to provide an additional functionality to jsonb (currently missing in PostgreSQL), such as a simple and effective way to search in nested objects and arrays, and more comparison operators with indexes support. We hope, that jsquery will be eventually a part of PostgreSQL. JsQuery is realized as an extension and is not available in the default PostgreSQL installation. It is available from GitHub under the same license as PostgreSQL and supports PostgreSQL 9.4+.

droite is a correction of eS expression parsers implemented in many different programming languages. Its usefulness is the same as JSON but droite utilizes eS expression, a Gauche scheme interpreter friendly S expression variant.

A high-performance JSON library written in ANSI C.

zzjson is a lightweight C library for reading, writing, querying and constructing JSON files and objects. Almost every component is optional at compile time. Full unicode support through readily available callbacks.
