Dmn JSON

From the App Store Source

Dmn JSON is the ultimate native toolkit for developers who live inside JSON payloads all day. Built to consolidates a dozen fragmented web tools into one fast, offline-first binary for iPhone, iPad, and Mac. Whether you're a backend engineer debugging an API, a frontend dev wiring up a new schema, or a QA validating payloads, Dmn JSON gives you every utility you need in a single tap. ◆ FORMATTER & MINIFIER Beautify unreadable JSON with custom indentation or compress it to a single line for network transfers. Copy, share via AirDrop, or save to your local library. ◆ DIFF CHECKER Compare two JSON documents visually using a Myers-diff algorithm. See exactly what was added, removed, or modified at a glance. ◆ INTERACTIVE VISUALIZER Render any JSON as a collapsible, color-coded tree. Strings in green, booleans in orange, nulls in gray, keys in neon blue. Search in real time, jump between matches, and edit any leaf value directly in the tree — the source JSON rewrites itself structurally, always valid. ◆ UI DASHBOARD GENERATOR Paste a JSON with mixed data and the engine auto-builds a live dashboard: numeric arrays become SwiftUI bar charts, booleans become interactive toggles, strings become info cards. Perfect for visualizing IoT telemetry or stats in seconds. ◆ POLYGLOT CONVERTER Transpile any JSON into production-ready code: • Swift (Codable structs) • TypeScript interfaces • Go structs with json tags • Kotlin data classes • SQL INSERT statements • MongoDB insertMany scripts • GraphQL queries • .env, XML, CSV (bidirectional) ◆ SCHEMA GENERATOR & VALIDATOR Infer a JSON Schema (Draft-7) from any payload, then validate documents against it. Get a precise, recursive list of errors — wrong types, missing required fields, and more. ◆ JSON PATCH (RFC 6902) Apply standard patch operations directly to your JSON, natively. ◆ jq SANDBOX Run JSONPath-style queries like `.users[0].email` against your data, locally. ◆ SIZE PROFILER Recursively analyze byte weight per key. Visual percentage bars instantly reveal which nodes are bloating your payload. ◆ UTILITIES GRID Base64, URL encode/decode, JWT header & payload decode, JSON flattener, sanitizer (auto-mask passwords and tokens), and a mock data generator that turns a schema into realistic test arrays. ◆ LOCAL LIBRARY Save, search, and reload your JSONs anytime. Powered by SwiftData, fully offline. ◆ DEEP LINK API Open Dmn JSON from any other app using the dmnjson:// URL scheme with zlib-compressed payloads. DESIGNED FOR SPEED • Haptic feedback on every action • Smart keyboard toolbar to reclaim screen space on iPhone • Forced dark mode with a high-contrast cyberpunk palette PRIVACY Everything runs on-device. No accounts, no telemetry, no servers. Your JSON never leaves your hardware. Stop juggling browser tabs and half-broken websites.
