JSON View vs JSON Formatter Viewer

JSON View is a clean JSON viewer and editor. Open, view, edit, format, and validate JSON files — all offline, no account required, no ads. Whether you're a developer debugging an API response, a data analyst inspecting config files, a student learning JSON syntax, or someone who just received a .json file and needs to read it — JSON View handles it efficiently. TREE VIEW — EXPLORE JSON VISUALLY Navigate complex, deeply nested JSON with a collapsible tree view. Each node shows the key name, value type, and child count at a glance. Tap to expand or collapse any object or array. Color-coded types make it easy to spot strings, numbers, booleans, and null values without reading every line. Auto-expands the first two levels when you open a file — so you see structure immediately, not a wall of collapsed nodes. TEXT VIEW — READ & EDIT WITH SYNTAX HIGHLIGHTING Switch to a full syntax-highlighted text view with line numbers. Every key, string, number, boolean, and bracket is color-coded for quick scanning. Edit your JSON directly in the text editor — fix typos, update values, restructure data. JSON View gives you both a visual tree view AND a real text editing mode with syntax highlighting, giving you the flexibility to work exactly how you want. FORMAT & BEAUTIFY Beautify messy, minified JSON into a clean, readable structure with one tap. Choose your indentation — 2 spaces, 4 spaces, or tabs. Minify bloated JSON into compact single-line output for APIs or configs. Sort keys alphabetically to organize your data. VALIDATE BEFORE YOU SAVE Real-time JSON validation catches syntax errors before you save. See exactly which line and column has the problem — no more guessing. JSON View validates your file every time you save, so you never accidentally corrupt a file. Auto-fix common mistakes like trailing commas, missing quotes, and extra brackets. OPEN JSON FROM ANYWHERE Pick a .json file from your device storage using the built-in file browser. Paste JSON directly from your clipboard — no file needed. Load JSON from any URL (paste an API endpoint and see the response). Receive JSON shared from other apps. Start from scratch with a blank file or use starter templates (API Mock, package.json, Config Map). JSON View works with the Files app — tap any JSON file and open it directly in JSON View. SAVE, SHARE & EXPORT Save changes back to the original file. Save as a new .json file anywhere on your device. Export to XML or PDF for sharing with non-technical colleagues. Share formatted JSON as text to any messaging or note-taking app. Copy the entire file to your clipboard with one tap. CONVERT BETWEEN FORMATS Convert JSON to XML and XML to JSON with a single tap. Useful when you need to switch between data formats for different systems, APIs, or team members. Transform key casing — convert between camelCase, snake_case, and PascalCase across all keys in your file. DESIGNED FOR REAL USE Modern, clean interface optimized for your device. Dark mode and light mode with system-aware auto-switching. Works completely offline — no internet connection needed. No account, no sign-up, no login. No data collection — your JSON files never leave your device. Handles deeply nested structures and large files smoothly. Built by Garoono — indie developers who ship useful tools for real people.

Paste messy JSON and get clean, readable, correctly indented output in one tap. JSONViewer formats, validates, and beautifies any payload — right on your iPhone, fully offline. Most JSON tools are websites that make you paste sensitive API data into a stranger's server. JSONViewer keeps everything on your device: paste a response, a config file, or a log export, and it pretty-prints with color syntax highlighting instantly. Invalid JSON is flagged with the exact reason so you fix broken payloads fast — no guessing, no round trips to a browser. WHAT YOU GET - Clean, indented JSON from any pasted or copied payload in one tap - Instant validation that pinpoints exactly why a payload is broken - Minify mode to strip whitespace down to a compact one-liner - An interactive, collapsible tree so you can read deeply nested data at a glance - JSONPath queries that pull the exact value out of a large response - A saved library of your own snippets plus ready-to-use sample payloads PERFECT FOR - Backend and mobile developers debugging API responses on the go - QA engineers checking payloads and config files away from a laptop - Students learning JSON structure with the built-in Learn guide - Anyone who needs to read or clean a JSON blob without opening a website WHY NOT JUST USE A WEB FORMATTER? Online formatters send your JSON to a remote server — a real problem when the payload holds tokens, user records, or internal data. JSONViewer does all parsing on-device, so your data never leaves your phone and works with no signal at all. PRIVACY Your JSON never leaves the device. No accounts, no servers, no tracking — everything runs locally, even in airplane mode. FULL ACCESS The Format tab — paste, validate, beautify, minify, and copy — is free. Premium unlocks the interactive tree view, JSONPath query, saved snippet library, and expand/collapse controls. Premium is available as a weekly or yearly subscription, or a one-time lifetime purchase: - Weekly subscription - Yearly subscription - Lifetime (one-time purchase, no renewal) Payment is charged to your Apple ID at confirmation of purchase. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Manage or cancel anytime in App Store settings. Paste your first payload and clean it up now.
