JSON Formatter
Beautify your JSON strings to make them readable or validate their structure to detect syntax errors instantly.
What Is JSON and Why Format It?
JSON (JavaScript Object Notation) is a lightweight data-interchange format. While machines prefer minified JSON for speed, developers and researchers need "Pretty Print" formatting to understand complex data structures. Our tool beautifies raw JSON instantly.
Supported JSON Data Types
| Type | Description | Example |
|---|---|---|
| String | Sequence of characters in quotes. | "Hello World" |
| Number | Integer or floating point. | 42 or 3.14 |
| Object | Collection of key-value pairs. | { "id": 1 } |
| Array | Ordered list of values. | [1, 2, 3] |
| Boolean | Logical value. | true or false |
