Punti chiave
- I parser AST localizzano con precisione errori di sintassi specificando riga e colonna.
- La generazione di tipi TypeScript crea contratti con tipizzazione statica partendo da strutture JSON.
- La minificazione riduce la dimensione dei payload di rete di circa il 30%.
- La conversione in YAML semplifica i file di configurazione per Docker e Kubernetes.

01.JSON Syntax Validation & AST Error Detection
JSON (JavaScript Object Notation) is a strict data interchange format. Parsers build Abstract Syntax Trees (AST) and report exact line/column positions for errors like trailing commas, unquoted keys, or mismatched brackets.

// JSON Validation with Error Reporting
function validateJSON(input: string): { valid: boolean; error?: string } {
try {
JSON.parse(input);
return { valid: true };
} catch (e: any) {
return { valid: false, error: e.message };
}
}02.Automatic TypeScript Interface Generation
TypeScript interfaces provide compile-time type safety. Our tool reverse-engineers JSON objects and arrays, inferring types (string, number, boolean, nested objects) and generating interface definitions.
03.YAML Conversion for Configuration Files
YAML (YAML Ain't Markup Language) is a human-readable superset of JSON used in Docker Compose, Kubernetes, and CI/CD pipelines. Our tool converts JSON to YAML syntax with proper indentation.
How to Format and Validate JSON
Step-by-step JSON formatting and validation workflow.
1
Paste JSON Data
Copy your JSON from API responses, config files, or code and paste into the input editor.
2
Auto-Format with Beautify
Click Beautify to apply 2-space or 4-space indentation for readability.
3
Inspect Syntax Errors
If invalid, view exact line and column positions of syntax violations.
4
Generate TypeScript Interfaces
Click "Generate TS Interface" to export statically-typed definitions for your codebase.
Frequently Asked Questions
JSON uses brackets and quotes; YAML uses indentation and colons. YAML is more human-readable but less strict.
