What is JSON and How is it Used
JSON is a lightweight, text-based data format used for transmitting data between web applications. It works with any language and is compatible with all current programming languages, such as Python, C#, and PHP.
JSON has a simple syntax that consists of key-value pairs, arrays, and nested objects, which makes it easy to read. It uses curly braces, square brackets, and various data types such as strings, numbers, booleans, and null values.
Modern applications rely on JSON for REST APIs, NoSQL databases, schema markups, etc. An online JSON formatter is a great way to clean up your script.
Why Format JSON Files
Formatted JSON files are essential for development efficiency and error prevention. Raw JSON data appears as compressed, single-line text that's impossible to read or debug. Without formatting, identifying syntax errors, missing brackets, or incorrect nesting becomes frustrating.
Formatting provides a clear visual hierarchy through proper indentation, line breaks, and spacing. Well-formatted JSON improves team collaboration as everyone can understand data structure.
