▶ About JSON

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate.

Features:

Key-value pair based text format
Supports strings, numbers, booleans, arrays, objects, and null
Widely used in Web APIs and configuration files

💡 Tip: All JSON processing is done locally in your browser; no data is sent to the server.
