Json Codable is a native macOS app that turns JSON into clean, type-safe Swift Codable models.
Paste or import JSON, choose your options, and generate Swift code that’s ready to drop straight into your iOS or macOS projects.
Features
• Convert JSON into Swift Codable models in seconds
• Generate struct or class types with CodingKeys
• CamelCase property names while keeping original JSON keys
• Smart type inference for Int, Double, Bool, arrays and nested objects
• Handles mixed-type arrays by falling back to [Any] when needed
• JSON editor with line numbers and smart-quote fixing
• Import JSON from files (.json, .txt) using a native open panel
• Syntax-highlighted Swift output (keywords, types, strings, comments)
• “Generate” success blink on the Swift panel for quick visual feedback
• Copy generated code to the clipboard or export as a .swift file
• Built-in history to save and search your favorite JSON snippets
• Works completely offline – your JSON never leaves your Mac
Json Codable is designed for Swift, SwiftUI and UIKit developers who work with APIs every day and want to spend less time writing boilerplate models and more time shipping features.
