What Are JSON Data Types?

When you work with JSON, it’s important to understand JSON Data Types. These data types help you define the kind of value you’re working with—text, number, true/false, or even a list.

JSON is used to send and store data between web apps and servers. If you don’t use the correct data types, your JSON will be invalid.

Different Types of JSON Data

Let’s look at the main JSON data types with simple examples:

1. String

Text in double quotes.

json

CopyEdit

"username": "james123"

2. Number

Includes whole numbers and decimals.

json

CopyEdit

"score": 95.5

3. Boolean

Only true or false.

json

CopyEdit

"isLoggedIn": false

4. Null

Means “no value” or empty.

json

CopyEdit

"nickname": null

5. Object

Group of key-value pairs inside {}.

json

CopyEdit

"profile": { "firstName": "James", "lastName": "Doe" }

6. Array

List of values inside [].

json

CopyEdit

"skills": ["HTML", "CSS", "JavaScript"]

Why JSON Data Types Matter

If you mix up data types—for example, using text where a number is expected—it can break your JSON code. This leads to errors when loading data into apps or websites.

To avoid this, always double-check your JSON Data Types before using or sharing your JSON file.
