Customization Options

Indentation Settings

You can customize how your JSON is formatted:

  • • 2 spaces (default) - Compact and standard
  • • 4 spaces - More readable for complex structures

Change this in Settings → Indentation

Before (Compact) 

{"name":"John","age":30,"city":"New York","hobbies":["reading","coding"]}

After (Formatted) 

{
  "name": "John",
  "age": 30,
  "city": "New York",
  "hobbies": [
    "reading",
    "coding"
  ]
}
