A JSON Beautifier is a tool that formats JSON (JavaScript Object Notation) data to make it more readable and structured. It adds proper indentation, line breaks, and spacing, making it easier for humans to view and work with JSON data.
Why use a JSON Beautifier?
✅ Improved Readability: JSON data can often be difficult to read when it's all in a single line. A beautifier makes the structure clearer with proper indentation and line breaks.
✅ Easier Debugging: With well-organized JSON, it's easier to spot errors like missing commas, incorrect brackets, or other formatting mistakes.
✅ Consistency: A beautifier ensures that your JSON follows a consistent formatting style, making it easier to maintain, especially in teams.
✅ Better for Collaboration: When sharing JSON data, a beautified version is much easier for others to understand.
Example of JSON Before and After Beautification:
Before Beautification:
json
{"name":"Alice","age":30,"city":"New York"}
After Beautification:
json
{
"name": "Alice",
"age": 30,
"city": "New York"
}
The beautified version clearly shows the structure with proper indentation and line breaks.

Prettier (can be used for various languages including JSON)
JSON Formatter & Validator (browser extensions)
