YAML to JSON Converter

Fast, free & browser-based conversion from YAML to JSON format.

What is a YAML to JSON Converter?

A YAML to JSON Converter is a browser tool that instantly transforms YAML (a human-readable configuration format) into JSON (a structured data format used by programming languages and APIs). This is useful when switching between config files, setting up APIs, or debugging data structures.

What is YAML?

YAML (YAML Ain’t Markup Language) is a clean and readable format used to structure data. It's popular in configuration files for tools like Docker, Kubernetes, GitHub Actions, and more. YAML uses indentation and newlines instead of symbols like braces or brackets, making it easier for humans to read and write.

What is JSON?

JSON (JavaScript Object Notation) is a compact, widely-used data format that represents structured data using key-value pairs, arrays, and objects. It’s the standard for APIs, web applications, databases, and modern frontend/backend communication.

Example

YAML Input:

name: Alice
age: 25
skills:
  - HTML
  - CSS
  - JavaScript
  

JSON Output:

{
  "name": "Alice",
  "age": 25,
  "skills": ["HTML", "CSS", "JavaScript"]
}
