JSON To YAML

What is JSON to YAML Conversion?

JSON (JavaScript Object Notation) and YAML (YAML Ain’t Markup Language) are both popular formats used for configuration and data interchange. While JSON is more compact and widely used in APIs, YAML is more human-readable, often used in Docker, Kubernetes, and DevOps pipelines.

This converter takes valid JSON input—either pasted or uploaded as a file—and generates equivalent YAML output. It’s especially useful for developers and DevOps engineers who need clean configuration files or want to make JSON more readable for versioning and collaboration.

Examples

Example 1: Basic JSON to YAML

JSON input:

{
  "name": "Alice",
  "age": 30
}

YAML output:

name: Alice
age: 30

Example 2: Nested Objects

JSON input:

{
  "user": {
    "name": "Bob",
    "contact": {
      "email": "bob@example.com",
      "phone": "123-456-7890"
    }
  }
}

YAML output:

user:
  name: Bob
  contact:
    email: bob@example.com
    phone: 123-456-7890

Example 3: Array of Objects

JSON input:

{
  "users": [
    {
      "name": "Alice",
      "role": "admin"
    },
    {
      "name": "Bob",
      "role": "editor"
    }
  ]
}

YAML output:

users:
  - name: Alice
    role: admin
  - name: Bob
    role: editor

Example 4: Booleans and Nulls

JSON input:

{
  "active": true,
  "subscription": null
}

YAML output:

active: true
subscription: null

Example 5: Mixed Types

JSON input:

{
  "id": 1001,
  "name": "Widget",
  "tags": ["new", "sale", "tech"],
  "available": true,
  "dimensions": {
    "width": 10,
    "height": 20
  }
}

YAML output:

id: 1001
name: Widget
tags:
  - new
  - sale
  - tech
available: true
dimensions:
  width: 10
  height: 20

How It Works

1. Input: Upload a .json file or paste your JSON code.

2. Convert: Click “Convert to YAML.” The tool automatically parses and formats the content.

3. Output: View your YAML result, then download or copy it as needed.

Features

• Supports nested objects and arrays

• Fast and lightweight conversion

• Downloadable .yaml output

• Clean formatting for readability

• No login or sign-up required

Use Cases

• DevOps: Easily turn .json Kubernetes config files into YAML format.

• API Developers: Convert OpenAPI specs or Postman exports to YAML-based tools.

• Data Exchange: Translate machine-readable JSON to more readable YAML for configuration.

• Version Control: Simplify diffs and collaboration by maintaining YAML formats in Git.

• Inter-tool Transfers: Use alongside tools like JSON to XML for data format transitions.

Pro Tips

• For accurate YAML, ensure your JSON keys are wrapped in double quotes and values are properly typed.

• YAML is sensitive to indentation—this tool automatically handles it for you.

• Arrays in JSON will be converted to bullet lists (-) in YAML.

• Want to validate your result? Use our YAML to JSON to double-check reversibility.

• If you’re working with APIs, explore JSON to XML to support older systems or SOAP-based services.
