What is YAML to JSON Conversion?

YAML (Yet Another Markup Language) is popular for configuration files due to its readability, while JSON (JavaScript Object Notation) is widely used for data transfer in APIs and web development. This tool translates YAML syntax into equivalent JSON structures, preserving keys, lists, and values accurately.

How It Works

Upload a .yaml file or paste your YAML directly.
Click Convert to JSON.
Instantly see the converted JSON output.
Copy or download your result as a .json file.

Examples

Example 1: Simple Key-Value Pairs

YAML input:

name: Alice
age: 30
active: true

JSON output:

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

Example 2: Nested Objects

YAML input:

user:
  name: Alice
  address:
    city: Paris
    zip: 75001

JSON output:

{
  "user": {
    "name": "Alice",
    "address": {
      "city": "Paris",
      "zip": 75001
    }
  }
}

Example 3: Lists and Arrays

YAML input:

languages:
  - Python
  - JavaScript
  - Go

JSON output:

{
  "languages": [
    "Python",
    "JavaScript",
    "Go"
  ]
}

Example 4: Boolean and Null Values

YAML input:

admin: false
bio: null

JSON output:

{
  "admin": false,
  "bio": null
}

Example 5: Combining Types

YAML input:

project:
  name: Qodex
  contributors:
    - name: Alice
      role: Developer
    - name: Bob
      role: Designer

JSON output:

{
  "project": {
    "name": "Qodex",
    "contributors": [
      {
        "name": "Alice",
        "role": "Developer"
      },
      {
        "name": "Bob",
        "role": "Designer"
      }
    ]
  }
}
