YAML to JSON Converter

What is YAML to JSON?

YAML to JSON is a simple and efficient tool for converting data in YAML format to JSON format. It's perfect for configuration file format conversion, API data transformation, and ensuring data compatibility across different systems.

With real-time conversion and indent adjustment features, this tool streamlines development work and enables quick data format changes.

Common Use Cases

• Configuration File Conversion: Transform Docker Compose, Kubernetes configuration files, etc.
• API Development: Convert OpenAPI specifications from YAML to JSON format
• Data Migration: Unify data formats between systems
• Document Conversion: Format changes in document management systems

How to Use

Basic Operations

1. Input YAML Data: Paste or type your YAML data into the left editor
2. Automatic Conversion: Data is converted to JSON in real-time and displayed in the right editor
3. Indent Adjustment: Choose JSON output indentation (2 spaces, 4 spaces, or minified)

Indent Settings

• 2 Spaces: Standard indentation (default)
• 4 Spaces: Enhanced readability indentation
• Minified: Minimized data size (no line breaks or spaces)

Conversion Example

Here's a practical conversion example:

YAML Input:

name: John Doe
age: 30
skills:
  - JavaScript
  - Python
  - Go
address:
  street: 123 Main St
  city: Tokyo
  country: Japan

JSON Output (2-space indent):

{
  "name": "John Doe",
  "age": 30,
  "skills": [
    "JavaScript",
    "Python",
    "Go"
  ],
  "address": {
    "street": "123 Main St",
    "city": "Tokyo",
    "country": "Japan"
  }
}
