What is JSON?

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

Here's a simple example of JSON:

{
  "name": "John Doe",
  "age": 30,
  "hobbies": [
    "reading",
    "cycling"
  ],
  "address": {
    "street": "123 Main St",
    "city": "Anytown"
  },
  "isStudent": false,
  "grades": null
}

How to open a JSON file?

You can open a JSON file with any text editor. For better readability, you can use code editors like VS Code, Sublime Text, or online JSON viewers.
