About

Json2Toon

Read full description

Json2Toon converts JSON to TOON and back — seamlessly. What is TOON? Token-Oriented Object Notation (TOON) is a compact, human-readable data format designed for LLM input. It combines YAML's clean structure with CSV-style tabular arrays to minimize tokens while maintaining clarity. In benchmarks, TOON achieves 40% fewer tokens and higher LLM accuracy than JSON. Why use Json2Toon? If you work with AI tools, APIs, or large datasets, you know tokens cost money and context windows have limits. TOON lets you pack more data into fewer tokens — saving costs and improving results. Features • Bidirectional conversion — JSON to TOON and TOON to JSON • Mixed content support — paste text with embedded JSON/TOON blocks and convert only the structured data • Syntax highlighting — multiple color themes for readability • Token counter — see exactly how many tokens your data uses • Keyboard shortcuts — fast workflow with ⌘[ ⌘] ⇧⌘V ⇧⌘C • Shortcuts integration — build automation workflows on iOS and macOS • Spotlight & Services — convert data without leaving your current app (macOS) 100% Private All conversions happen locally on your device. No network requests, no data collection, no account required. Works completely offline.

【Master Your Cursor on iOS】 As a developer, I was frustrated with editing code and managing SSH sessions on my iPhone. The native "magnifying glass" cursor is slow, and my fingers often blocked the text I was trying to select. I built VimKey to scratch my own itch. It brings the precision of desktop editing to your mobile device. Key Features: * Vim-Style Navigation: Use the legendary HJKL (←↓↑→) keys to move the cursor. Keep your hands on the keyboard and fly through text. * Dedicated Arrow Keys: Includes a standard directional pad for precise control without blocking the screen. * Dual Layouts: Seamlessly switch between the navigation layout and a standard QWERTY keyboard (Unlock QWERTY for 30 minutes by watching a short ad, or unlock forever with a one-time purchase). * Privacy First: We respect your data. "Full Access" is requested ONLY to provide haptic feedback and click sounds. We strictly do NOT collect, store, or transmit your keystrokes. Important Note: * Due to browser limitations on iOS, special keys (Esc, Tab, Ctrl) and arrow keys do NOT work in browser-based WebSSH clients. For the best experience, please use a native Terminal app. Contact: I'm actively improving this app based on user feedback. Email: mozhenbear@zodic.dev

Verdict

The call
