5 days ago · In this example program, we first open the JSON file, read its contents into a string, and parse the JSON data using the cJSON_Parse () function. We then modify the JSON data by replacing the value of the “name” key with a new string, adding a new key-value pair for “phone”, and changing the value of the “age” key to 32.

You basically have *_add functions to create JSON objects, equivalent *_put functions to release their memory, and utility functions that convert types and output objects in string representation.

Nov 28, 2023 · In this post, we’ll dive into cJSON examples that demonstrate how to parse a JSON file, write data to a JSON file, and print a JSON object in C. These examples are designed to be clear, concise, and easy to follow for better learning and readability.

Extremely lightweight, easy-to-use & blazing fast JSON parsing library written in pure C - whyisitworking/C-Simple-JSON-Parser

Nov 13, 2017 · I'd suggest either adding a explicit type check or splitting your string parsing code into a separate function (as described below) and calling it directly from json_parse_object().

jsmn (pronounced like ‘jasmine’) is a minimalistic JSON parser in C. It can be easily integrated into the resource-limited projects or embedded systems. You can find more information about JSON format at json.org. Library sources are available at https://github.com/zserge/jsmn.

Sep 12, 2023 · This article introduces the JSON parser of the open source C library Melon. I believe many readers have heard of or even used the cJSON. So this article will compare cJSON and Melon’s JSON component. Let’s take a look together below. Encode Suppose we want to build the following JSON:
