Json2Toon converts JSON to TOON and back โ€” 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 โ€” saving costs and improving results. Features โ€ข Bidirectional conversion โ€” JSON to TOON and TOON to JSON โ€ข Mixed content support โ€” paste text with embedded JSON/TOON blocks and convert only the structured data โ€ข Syntax highlighting โ€” multiple color themes for readability โ€ข Token counter โ€” see exactly how many tokens your data uses โ€ข Keyboard shortcuts โ€” fast workflow with โŒ˜[ โŒ˜] โ‡งโŒ˜V โ‡งโŒ˜C โ€ข Shortcuts integration โ€” build automation workflows on iOS and macOS โ€ข Spotlight & Services โ€” 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.

REAL SITUATIONS WallScan WAS BUILT FOR The carpenter restoring an old beam โ€” about to cut into hundred-year-old timber full of forgotten nails. WallScan spikes every time a nail comes near the surface, saving your saw blade. The electrician working blind โ€” the junction box used to be there, but the drywall got patched and painted. WallScan locates the screws so you don't punch a new hole off target. The homeowner mounting a TV โ€” slide your phone across the wall, watch the meter peak, drill into solid wood every time. The renter who can't make mistakes โ€” WallScan tells you exactly where the studs are, so the shelf goes up on the first try. The DIY furniture maker reclaiming old pallets โ€” find the buried nails before they ruin your planer or table saw blade. HOW IT WORKS Your iPhone has a built-in magnetometer โ€” the same sensor that powers the compass. Metal screws and nails disturb the local magnetic field. WallScan reads those disturbances in microtesla (ยตT), shows them on a precision analog meter, and triggers a haptic and sound alert when you pass over one. KEY FEATURES - Live magnetic field meter in microtesla with a smooth analog needle - Color-coded scale, green to red as you get closer to metal - Haptic vibration plus audio tone when a stud is detected - Adjustable sensitivity for plaster, drywall, plywood and hardwood - Visual scan trace showing your sweep path - Calibration mode for clean, drift-free readings - 100% offline, works anywhere with no internet - Clean LCD-style interface, distraction-free TIPS FOR BEST RESULTS - Take off your phone's magnetic case and any MagSafe accessory - Calibrate by waving the phone in a figure-8 if readings drift - Move slowly across the surface, around 5 cm per second - Sweep both horizontally and vertically PRIVACY WallScan never collects your location, microphone, camera or any personal data. The magnetometer is a passive sensor that does not transmit anywhere. Your scans live and die on your device. Stop guessing. Stop drilling holes you'll regret. SUBSCRIPTION INFORMATION WallScan offers two auto-renewable subscription options to unlock Pro features (Unlimited wall scans, Pro sensitivity mode, Find studs / nails / pipes, No ads): - WallScan Pro Weekly โ€” $4.99 per week - WallScan Pro Yearly โ€” $29.99 per year (about $0.58 per week, save 88%) Payment will be charged to your Apple ID account at confirmation of purchase.
