About this app
A free, offline, multi-language JSON Editor, Viewer and Converter.
JSON Studio is a fast, beautiful JSON editor and viewer built for phones. Paste any JSON and instantly see it syntax highlighted, validated and organized — then format it, explore it as a tree, convert it, query it or save it for later. Everything runs on your device: no account, no upload, your data never leaves your phone.
SMART CODE EDITOR
• Live syntax highlighting with line numbers
• Real-time validation with the exact error line — tap the error chip to jump straight to the problem
• One-tap Format (2 spaces, 4 spaces or tabs) and Minify
• Format-on-paste: messy JSON becomes readable the moment you paste it
• Word wrap, adjustable font size and a live cursor position, size and key counter
INTERACTIVE TREE VIEWER
• Explore any document as a collapsible tree with color-coded types
• Expand or collapse everything with one tap
• Search across keys and values and get every matching path
• Tap any value to copy it, tap any result to copy its full path
POWER TOOLS
• Sort keys A–Z through the whole document
• Convert JSON to YAML, CSV, XML or TypeScript interfaces
• JSONPath queries: $.users[*].email, $..id and more
• Compare two JSON documents and see every added, removed and changed path
TEMPLATES & SNIPPETS
• Start from ready-made templates: user profile, REST response, app config, todo list and more
• PRO templates: package.json, GeoJSON, JSON Schema, OpenAPI, feature flags, invoice
• Save your own snippets and reload them anytime
• Export to a .json file or share the raw text in one tap
MADE TO BE LOOKED AT
• Eight hand-tuned editor themes, light and dark: Porcelain, GitHub, Solarized, Graphite, One Dark, and more themes Dracula, Monokai and Nord
• Real coding fonts including JetBrains Mono, Fira Code and Source Code Pro
• Clean, spacious design with settings tucked into elegant bottom sheets
• English and Spanish, following your system language automatically
Whether you are debugging an API response, cleaning a config file, learning JSON or building an app, JSON Studio turns a chore into something you actually enjoy. Download JSON Studio and give your JSON the editor it deserves.
