JSON View vs JSON Editor

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.

Json Editor: Smart Json turns a wall of JSON into something you can actually read on a phone. The same document, three linked views. Edit in any of them and the other two follow — the text is always the source of truth, so nothing drifts out of sync. EDITOR • Syntax highlighting that re-tokenizes only what you typed, so it stays fast • Line-number gutter, wrap and font size controls • A punctuation bar above the keyboard: braces, brackets, quotes, true, false, null, indent, undo and redo • Invalid JSON gets a plain-language banner naming the problem, its line and its column. Tap Go to jump the caret there, or Fix to repair comments, trailing commas, single quotes and unquoted keys automatically TREE • A collapsible outline with indent guides, type badges and child counts • Search across keys and values, filter by type • Edit any node in place: rename, change type, reorder, duplicate, add, delete GRAPH • A tidy node-link diagram, left-to-right or top-to-bottom • Pinch to zoom, pan, tap a node to expand it, fit to screen • Tap a node to open an editor docked right underneath it — the graph edits as well as it browses • Expand all, expand to a depth, or expand one subtree • Export the graph as PNG or SVG FIND WHAT YOU NEED • One find bar in every view. Text search in the editor with match case and wrap-around; structural search in the tree and graph with scope and type filters, stepping through hits • JSONPath: type an expression and watch it evaluate live, tinting its matches in the editor, the tree and the graph at once. A documented subset of RFC 9535, filter expressions included COMPARE • Diff the open document against a file, the clipboard or a URL • Structural, not textual — reformatting is not a change • Changed subtrees are tinted in the graph, and array elements are paired by identity when they have one CONVERT • Preview your document as YAML, CSV, TOML or XML, each with a plain statement of what that format cannot carry DOCUMENT ACTIONS • Beautify, minify, sort keys, auto-fix • Escape and unescape a JSON string literal • Copy in, copy out, share, and a statistics breakdown • Undo and redo everything, with one history per document shared by every view GETTING JSON IN • Open files from iCloud Drive and Files, with proper open, save and rename • Start a document from the clipboard or from a URL. URL requests are a GET with your own headers, and the last ten are remembered; header values are stored in the keychain, not in plain preferences • A share extension accepts JSON from any app • JSON5 files open too, normalized to JSON with a banner saying what that cost • Imports are named after where they came from, like mydomain.com-users.json BUILT RIGHT • Native SwiftUI for iPhone and iPad, with full keyboard support • Light or dark, or pinned to whichever you prefer • A hand-written parser that preserves key order and keeps number literals exactly as written — no precision lost on a round trip • Works entirely offline. No account, no sign-in, no analytics, no data leaves your device SMART JSON PRO The app is free, and every feature computes and shows you its result for free. Pro is for keeping that result: • Extract JSONPath matches to a new document, plus query history and saved queries • Text diff, jump between changes, copy as a patch, choose the array identity field • Save, share or open a conversion to YAML, CSV, TOML or XML --- Terms of Use: https://mygems.app/term Privacy Policy: https://mygems.app/privacy
