Examples

Basic Configuration

Converting a simple JSON configuration to YAML

Input:

{
  "server": {
    "host": "localhost",
    "port": 8080,
    "debug": true
  }
}

Output:

server:
  host: localhost
  port: 8080
  debug: true

Complex Structure

Converting nested JSON with arrays

Input:

{
  "users": [
    {
