How to Convert C to JSON - Complete Step by Step Guide
Learn how to convert C structs, arrays, and code to JSON format with our free online converter tool for embedded systems and IoT applications.
Input Your C Code
Start by pasting your C struct initialization, struct definition, or data structure that needs to be converted to JSON format. The tool supports C structs and nested structures.
Example: C Struct Initialization
Here's a typical C struct:
struct Person { char name[50]; int age; char email[100]; int isActive; }; struct Person person = { .name = "John Doe", .age = 30, .email = "[email protected]", .isActive = 1 };
Click Convert Button
Click the green "Convert" button to send your C code to our backend API for processing. The converter transforms C syntax to JSON format, handling integer values, arrays, and proper quote formatting.
Example: Converted JSON Output
The same data in JSON format:
{ "name": "John Doe", "age": 30, "email": "[email protected]", "isActive": 1 }
Get Valid JSON Output
The tool produces properly formatted, valid JSON that's ready to use in your applications, APIs, or configurations.
Copy or Download JSON
Copy the JSON to your clipboard or download it as a .json file for use in your C projects or embedded systems.
What is C to JSON Conversion?
C to JSON conversion transforms C data structures like structs, arrays, and initializations into standard JSON format. This process converts C-specific syntax into JSON-compliant syntax for data interchange and configuration management.
The conversion is essential for embedded systems, IoT applications, and system programming where JSON is the standard format for data exchange. You can also convert other languages like C# to JSON, Python to JSON, or Java to JSON using our related tools.
Frequently Asked Questions About C to JSON Conversion
How do I convert C struct to JSON?
Simply paste your C struct initialization into the converter. It will automatically convert C syntax (integers, char arrays, struct fields) to valid JSON format. The output can then be formatted or minified based on your needs.
Does the converter handle nested C structs?
Yes! The converter properly handles nested structs, arrays, and mixed data structures, converting them to equivalent JSON representations while maintaining the structure. You can also convert the reverse direction using our JSON to C converter.
What C types are supported?
The converter supports C structs, arrays, char arrays (strings), integers (int, long), floating-point numbers (float, double), and nested structures. These are converted to their JSON equivalents: objects, arrays, strings, and numbers.
Is the output valid JSON?
Yes! The converter produces standard, valid JSON that can be used in any application or API. The output is properly formatted and validated. You can further validate the JSON or convert it to other formats like TypeScript or Python.
Is the C to JSON converter free?
Yes, completely free with no limitations on data size or conversion frequency. No registration required. Check out our other free tools like JSON formatter, JSON validator, and JSON to Table converter.
