Input JSON:

{
  "service": "web",
  "replicas": 3,
  "ports": [80, 443],
  "env": {
    "NODE_ENV": "production"
  }
}

Converted YAML:

service: web
replicas: 3
ports:

env:
  NODE_ENV: production

• Readable: Indentation-based structure is easy to scan.
• Config-ready: Popular in Kubernetes, Docker Compose, and CI/CD.
• Compact: Less punctuation than JSON for large configs.

• Tabs vs spaces: Use spaces only. Tabs break YAML parsers.
• Indentation: Align nested keys consistently.
• Special characters: Quote strings with colons or hashes.
• Duplicate keys: Avoid repeated keys in the same map.

• Infrastructure: Generate YAML for Kubernetes manifests.
• Automation: Convert API output into pipeline configs.
• Docs: Share readable configuration examples.

• JSON viewer for validation before conversion.
• JSON to CSV converter for spreadsheet exports.
• JSON to XML converter for XML integrations.

Conversion runs in your browser with zero uploads. Your JSON stays on your device.

• RFC 8259 - The JSON Data Interchange Syntax
• YAML 1.2.2 Specification
