JSON Parser
A JSON parser is a software tool or library that reads and interprets JSON (JavaScript Object Notation) data, converting it into a structured format (e.g., objects, arrays, or native data types) that a programming language can manipulate. It validates the JSON syntax for correctness and handles tasks like parsing strings, numbers, booleans, null values, and nested structures. Parsers are essential for applications that consume or produce JSON data, such as web APIs, configuration files, and data storage.
Developers should learn and use JSON parsers when working with web APIs, configuration files, or any data interchange format, as JSON is a ubiquitous standard for data serialization. They are crucial for parsing API responses in web development, reading settings in applications, and processing data in mobile or desktop apps. Using a parser ensures data integrity, handles errors gracefully, and simplifies data manipulation compared to manual string parsing.
