Example Before and After

Here’s an unformatted JSON:

{"name":"Amit","email":"amit@example.com","roles":["admin","user"],"active":true}
    

After using this JSON Formatter:

{

What’s the Difference Between JSON Formatter & Decoder?

JSON Formatter: Just makes your JSON pretty—good spacing, indentation, and readability.
JSON Decoder: Converts JSON into PHP array or usable data structure in your code.

How This Tool Works Behind the Scenes

We use json_decode() to check if your JSON is valid or not. If it’s valid, then we format it back using json_encode() with JSON_PRETTY_PRINT. No data is stored. Everything runs instantly.

Tips for Clean JSON Formatting

• ★ Always use double quotes in keys and strings
• ★ Remove any trailing commas (last value in object/array)
• ★ Validate JSON before formatting to avoid errors
• ★ Combine with tools like Postman or Swagger for full workflow
