JSON Formatter – Free Online Tool | TradeInfo.Online
Introduction
Raw JSON data can be dense, unstructured, and difficult to read—especially when returned from APIs or databases without proper formatting. That’s where the JSON Formatter from TradeInfo.Online comes in. This tool transforms jumbled JSON text into clean, indented, and readable format in seconds, making it easier to interpret and debug.
Whether you're a developer working with complex APIs, a data analyst reviewing nested objects, or a student learning about data structures, this free formatter streamlines your workflow.
What Is a JSON Formatter?
A JSON Formatter is a tool that takes unformatted or minified JSON data and adds proper spacing, indentation, and line breaks to make it readable. This process is known as pretty-printing.
For example:
Minified JSON:
json
CopyEdit
{"name":"John","age":30,"address":{"city":"New York","zip":"10001"}}
Formatted JSON:
json
CopyEdit
{_x000D_
"name": "John",_x000D_
"age": 30,_x000D_
"address": {_x000D_
"city": "New York",_x000D_
"zip": "10001"_x000D_
} }
