Przekształć nieporządny JSON w pięknie sformatowany, czytelny kod z odpowiednimi wcięciami i podświetlaniem składni. Niezbędny do debugowania złożonych struktur JSON, analizy odpowiedzi API i dokumentacji kodu. Zawiera walidację składni w czasie rzeczywistym i wykrywanie błędów.
Advanced JSON Formatter

Transform JSON into readable code with smart indentation.

Customizable indentation Syntax validation Tree view Bulk processing for multiple JSON files Interactive collapsible tree view for complex structures Export formatted JSON with customizable styling
Practical Examples
API Debug

Improved readability

BEFORE (Minified JSON) 
{}
AFTER (Beautified JSON) 
{}
Configuration File Formatting

Format configuration files for better maintainability

BEFORE (Minified JSON) 
{"server":{"host":"localhost","port":3000,"ssl":{"enabled":true,"cert":"/path/to/cert.pem","key":"/path/to/key.pem"}},"database":{"type":"postgresql","connection":{"host":"db.example.com","port":5432}}}
AFTER (Beautified JSON) 
{
  "server": {
    "host": "localhost",
    "port": 3000,
    "ssl": {
      "enabled": true,
      "cert": "/path/to/cert.pem",
      "key": "/path/to/key.pem"
    }
  },
  "database": {
    "type": "postgresql", 
    "connection": {
      "host": "db.example.com",
      "port": 5432
    }
  }
}
