What is a JSON Beautifier?
A JSON Beautifier takes compact, minified JSON and reformats it into a more readable, human-friendly structure using indentation and line breaks. This makes it easier to view, understand, and debug complex data.
What is JSON?
JSON (JavaScript Object Notation) is a lightweight format used for storing and exchanging data between a server and a client. It’s widely used in web development, APIs, configuration files, and NoSQL databases like MongoDB. However, raw JSON is often minified — which means it’s compressed to save space, removing all unnecessary whitespaces.
Why Beautify JSON?
- Improved readability: Beautified JSON is structured with indents, making nested objects easy to understand.
- Easier debugging: Developers can spot missing brackets, typos, or invalid keys more easily.
- Cleaner documentation: Beautified JSON looks better when copied into docs or shared with a team.
- No data loss: Beautification is a visual format change only — the content remains intact.
How This Tool Works
- Paste your compact or minified JSON into the input box.
- Click the "Beautify JSON" button.
- The tool parses your data and returns a pretty-formatted version instantly.
- No server required — the conversion happens entirely in your browser.
Example
Minified JSON:
{"name":"Alice","age":25,"skills":["JS","HTML","CSS"]}
Beautified JSON:
{
"name": "Alice",
"age": 25,
"skills": [
"JS",
"HTML",
"CSS"
]
}
