JSON Brace: Viewer & Formatter

JSON Brace 3.0 is here – a full JSON viewer for iPhone, iPad, and Mac, plus the Safari extension. 15 new themes, big accessibility upgrade, and search is now free.

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.
