The guide

What is JSON Formatting?

JSON (JavaScript Object Notation) is standard for data exchange, but raw JSON from APIs is often minified (all one line) to save bandwidth. This tools helps you:

Beautify: Add indentation and newlines to make it readable.
Minify: Remove whitespace to reduce file size for production.
Validate: Check for syntax errors like missing quotes or trailing commas.

Common JSON Errors

Trailing Commas: {"a": 1,} is invalid in standard JSON.
Single Quotes: JSON strings must use double quotes "key": "value", not 'key': 'value'.
Undefined/Functions: JSON cannot store JS functions or undefined.
