JSON View

Read full description

JSON View is a clean JSON viewer and editor. Open, view, edit, format, and validate JSON files β€” 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 β€” JSON View handles it efficiently. TREE VIEW β€” 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 β€” so you see structure immediately, not a wall of collapsed nodes. TEXT VIEW β€” 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 β€” 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 β€” 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 β€” 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 β€” 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 β€” 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 β€” 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 β€” no internet connection needed. No account, no sign-up, no login. No data collection β€” your JSON files never leave your device. Handles deeply nested structures and large files smoothly. Built by Garoono β€” indie developers who ship useful tools for real people.
