JSON Brace: Viewer & Formatter

JSON Brace turns raw JSON into a clean, readable tree – in a native app on your iPhone, iPad, and Mac, and right inside Safari.

APIs, logs, configs, exports – JSON is everywhere, but reading it raw is painful. JSON Brace formats it instantly into a collapsible tree you can explore, search, and copy from.

THE APP
• Open any JSON and explore it as an interactive tree
• Collapse and expand nodes to focus on what matters
• Fast search with match highlighting
• Copy values or the whole document in one tap
• RAW mode when you need the original text
• Quick Look on the Mac: press Space on a JSON file in Finder for an instant preview in your theme

THE SAFARI EXTENSION
• Automatically detects and formats JSON on web pages
• Perfect for checking API responses right in the browser
• Same viewer, same themes, same shortcuts – no extra setup

MADE TO LOOK GOOD
• 19 carefully tuned themes: Solarized, Dracula, Nord, GitHub, Monokai, One Dark, Tokyo Night, Gruvbox, Catppuccin, Rosé Pine, and more
• Light, dark, and system appearance
• The whole app follows your theme, not just the tree

BUILT FOR EVERYONE
• Full VoiceOver support
• Complete keyboard navigation
• Adjustable text size and Dynamic Type
• High Contrast theme and type markers that don't rely on color alone

FREE AND PRO
The core viewer is free: formatting, tree navigation, search, and copying. JSON Brace Pro unlocks the full theme collection, inline previews, expansion depth control, saving to a file, and copying any subtree, key, or path. Pro is a one-time purchase – no subscription – and supports Family Sharing.

PRIVATE BY DESIGN
Everything happens on your device. No servers, no accounts, no tracking, no analytics. Your data never leaves your iPhone, iPad, or Mac.
