How it works

Parsing Input

The Ruby hash is parsed, handling symbol keys (`:key`), string keys (`'key'`), hash rockets (`=>`), and nested structures. It attempts to evaluate the input safely.

Type Conversion & Formatting

Ruby symbols and strings are converted to JSON strings (with double quotes), `nil` becomes `null`, arrays remain arrays, and the structure is formatted as standard JSON.

Examples

Ruby Hash

{
  name: "Alice Wonderland",
  age: 30,
  is_student: false,
  courses: ["Literature", "Logic"],
  address: {
    street: "123 Rabbit Hole Ln",
    city: "Fantasia",
    zip: nil
  },
  'string-key' => 'value for string key'
}

JSON

{
  "name": "Bob The Builder",
  "age": 45,
  "isStudent": false,
  "skills": ["Construction", "Problem Solving", "Teamwork"],
  "address": {
    "city": "Bobsville",
    "country": "USA"
  },
  "contact": null
}
