How to Use JSON to YAML Converter

1. Input JSON Data

Paste your JSON data in the input area. Supports nested objects and arrays.

3. Review YAML

Check the generated YAML structure and formatting.

4. Download Result

Copy or download the YAML file for use in your projects.

Conversion Rules

🏗️ Object to Map

JSON objects become YAML maps with key-value pairs.

{ "name": "value" }

name: "value"

📋 Array to List

JSON arrays become YAML lists with dash prefix.

["a", "b"]

- "a"

- "b"

🔤 Primitive Types

String, number, and boolean values maintain their types.

{ "id": 123, "active": true }

id: 123

active: true

🚫 Null Values

Null values become explicit null in YAML.

{ "empty": null }

empty: null

Conversion Example

Input JSON:

{
  "app": {
    "name": "MyApp",
    "version": "1.0.0",
    "config": {
      "debug": true,
      "port": 3000
    },
    "dependencies": [
      "express",
      "react"
    ]
  }
}

Generated YAML:

app:
  name: "MyApp"
  version: "1.0.0"
  config:
    debug: true
    port: 3000
  dependencies:
    - "express"
    - "react"

YAML Use Cases

⚙️ Configuration Files

Application configs, Docker Compose, and infrastructure as code

📚 Documentation

API documentation, project specs, and technical writing

🔄 DevOps

CI/CD pipelines, Kubernetes manifests, and deployment configs

Best Practices

✅ Structure Design

Keep JSON structure clean and avoid deeply nested objects for readable YAML.

💡 Naming Convention

Use meaningful property names as they become YAML keys.

⚠️ Indentation

YAML is sensitive to indentation. The tool handles this automatically.
