Read full description

Focal is a fast, private JSON viewer that works completely offline. Open a JSON file and Focal turns it into a clean, collapsible tree you can actually read — no pasting into a website, no uploading, nothing leaving your device. Huge exports open in an instant, search finds any key or value, and the inspector shows you the exact bytes from the file, never silently reformatted. • OFFLINE & PRIVATE — your JSON never leaves your device. No account, no upload, no tracking, no ads. • OPENS HUGE FILES — an indexed viewer opens massive JSON in an instant and scrolls smoothly. • SEARCH ANYTHING — find any key or value instantly and jump straight to each match. • EXACT SOURCE — inspect the real bytes from the file, never "prettified" behind your back. • ONE APP, EVERY DEVICE — a focused reader for iPhone, iPad and Mac. Perfect for developers, QA and anyone who works with APIs, config files or data exports and just wants to read JSON quickly and privately.
