Json Genie vs JSON Viewer

**Open JSON. Know what’s inside.** Open, understand and edit JSON on your iPhone or iPad without working through a wall of raw text. Whether someone sent you a JSON file or you regularly work with API responses and configuration files, Json Genie makes it easy to explore your data, find what matters and make changes. No coding needed. No account required. Your JSON is processed on your device. **OPEN YOUR JSON, YOUR WAY** Open JSON and JSONC from: • Files on your device • Mail, shared files and other apps • Cloud storage apps • Pasted text • Web links and API URLs • Supported ZIP archives **EXPLORE WITHOUT GETTING LOST** Browse your file in a clear, structured view. Open nested sections and lists (JSON objects and arrays) one level at a time, then easily find your way back. Keep multiple files open in tabs and switch between them without reopening them. **EDIT WITHOUT THE FUSS** Change values in simple forms without manually managing commas, brackets or quotation marks. • Edit text, numbers, true/false values and null • Add, delete, clone, move and reorder entries • Work with objects, arrays and individual values • Copy and reuse data with paste history **FIND IT. SKIP THE SCROLL.** Search keys, values and paths across your file, then jump directly to matching results. Need a more precise search? Use filters such as: • id: 3 • game.id: 3 • city: "Austin" **SEE EXACTLY WHAT CHANGED** Compare two JSON files or open tabs. Inspect differences in objects, arrays and values with clear before-and-after details. Check changes directly on your device without uploading your JSON to an online comparison tool. **BRING YOUR FILES TOGETHER** Merge JSON files into one new result while keeping your originals unchanged. Review the merge summary, inspect the combined data, then save or share it. **SAVE IT THE WAY YOU NEED IT** Choose readable formatting for people or a compact file for sharing and other tools. • Pretty-print and beautify JSON • Minify JSON by removing unnecessary spacing • Sort keys alphabetically • View raw JSON text • Save or share JSON as text or as a file **YOUR JSON, PROCESSED LOCALLY** Opening, viewing, editing, searching, comparing, merging and formatting happen on your device. Your JSON content is not uploaded to our servers for these operations. No account required. You choose when to export or share your files. **FREE TO USE. OPTIONAL PREMIUM.** Start using Json Genie for free. Premium removes ads, expands file and tab limits, increases history and unlocks extra themes.

Paste a JSON blob — an API response, a config file, a log payload — and JSONView turns it into a collapsible, colour-coded tree the moment it lands. Validate it with an error that names the exact line and column, format or minify it, and copy it back out. Everything happens on your iPhone, offline, so your payload never touches a web tool. Most JSON apps wrap the same lenient system parser. JSONView ships its own strict RFC 8259 engine: it preserves your key order instead of scrambling it, keeps number literals exactly as written, rejects the trailing commas other parsers silently swallow, and warns you about duplicate keys — with the position of both copies. WHAT YOU GET • Paste an API response and read it as a collapsible tree in under a second, with keys, strings, numbers and booleans each in their own colour • Broken JSON tells you exactly where: "Line 14, column 27 — trailing comma before '}'" instead of a shrug • Duplicate keys are flagged with both positions, so the bug that only bites in production gets caught on your phone • Find any key or value in a deep payload and jump to it with its full $.path[3].to.node • One tap copies a value, its path, or the whole document — pretty-printed or minified — to the clipboard • Round-tripping never rewrites your data: key order survives, 1e3 stays 1e3, -0 stays -0 PERFECT FOR • Backend and mobile developers checking an API response away from the desk • QA engineers pinning down exactly which field broke the build • Support and ops engineers reading the log payloads customers send in • Anyone learning what valid JSON actually is, from a parser that explains every rejection WHY NOT JUST A WEB FORMATTER? Every browser JSON tool means pasting your payload — auth tokens, emails, customer records — into someone else's server. JSONView parses entirely on-device and works in airplane mode. It also opens .json files straight from Files, Mail or Slack, so you skip the copy-paste dance entirely. PRIVATE BY DEFAULT No network calls. No account. Your documents are parsed and stored only on your iPhone, and your saved library never leaves the device. FULL ACCESS JSONView Pro unlocks the complete toolkit: an unlimited saved-document library, minify to clipboard, .json file export, custom indent width, and A-to-Z key sorting. Choose a weekly plan, a yearly plan, or a one-time lifetime purchase. Weekly and yearly plans are auto-renewing subscriptions; lifetime is a single payment. Copy a JSON payload, open JSONView, and tap Paste — the tree is already waiting.
