JSON to CSV Converter

Valid JSON Structure:

[
  {
    "name": "John Doe",
    "age": 30,
    "email": "[email protected]"
  }
]

Nested Objects (will be flattened):

{
  "user": {
    "name": "Jane",
    "address": {
      "city": "New York",
      "zip": "10001"
    }
  }
}

Becomes columns: user.name, user.address.city, user.address.zip

Arrays (will be joined with semicolons):

{
  "name": "John",
  "hobbies": ["reading", "swimming", "coding"]
}

Hobbies column will contain: "reading; swimming; coding"

Important Notes:

• JSON must be valid (use quotes around keys and string values)
• Single objects will be converted to single-row CSV
• Arrays of objects work best for multi-row CSV output
• Nested objects are flattened using dot notation
• Special characters in values are properly escaped
