What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format used to store and exchange data between a client and a server. It is easy for humans to read and write, and easy for machines to parse and generate, which makes it the most commonly used format for APIs and web applications.

JSON Structure Explained

JSON data is structured using key-value pairs and supports the following data types:• Objects – collections of key-value pairs enclosed in curly braces { }
• Arrays – ordered lists enclosed in square brackets [ ]
• Strings – text values enclosed in double quotes
• Numbers – integer or floating-point values
• Booleans – true or false
• Null – empty or missing values

Tree View vs Text View

Tree View displays JSON in an expandable and collapsible structure, making it easy to navigate large or deeply nested JSON files.Text View allows you to view and edit raw JSON directly, which is useful for copying, modifying, or pasting JSON into API requests or configuration files.
