JSON Editor

JSON Editor — view, edit & format JSON files with ease
A fast, offline JSON editor and viewer built for your phone. Whether you're a developer debugging an API response, working with config files, or just need to read a JSON file on the go, JSON Editor gives you everything in one clean, distraction-free app.
THREE WAYS TO VIEW YOUR DATA
• Text — edit raw JSON directly with syntax highlighting and line numbers
• Tree — browse the structure, expand or collapse nodes, and see type labels at a glance
• Table — view arrays of objects as a clean, scrollable grid
SMART EDITING TOOLBAR
• Format — pretty-print messy JSON in one tap
• Compact — minify to a single line
• Fix — auto-repair common JSON mistakes
• Find & Replace — search the whole document and replace matches
• Undo & Redo — step backward or forward through every edit
• Wrap & Unwrap, Expand & Collapse, and a quick insert bar for keys, strings, numbers, booleans, null, objects and arrays
LIVE VALIDATION
Every file is checked as you type. A clear "valid JSON" indicator, byte size, and line/column position keep you informed, while files with problems are flagged so you can fix them fast.
POWERFUL FILE MANAGEMENT
• Quick access to recent files with status badges (valid / error)
• Create a new JSON, import a file, or paste from the clipboard
• Browse folders like Downloads and Projects, or open any folder on your device
• See storage usage at a glance
COPY, SHARE & SAVE
Copy formatted JSON, share it anywhere, and rely on autosave so you never lose your work. A built-in quick guide explains every view and tool, so you're productive from the very first launch.
