JSON Tools

Open JSON files directly from anywhere: Tap any .json file in Mail, Files, Safari, or other apps to open it instantly in JSON Tools. Explore, format, and transform your JSON without extra steps.

Version 6.0 is the biggest update yet, bringing schema validation, a redesigned file workflow, and a faster, more polished editor. • Schema Validation: Validate JSON against JSON Schema and XML against XSD right inside the app. Pick a schema once and it stays attached to your file with live error reporting. • Recent Files: A new jump-list sheet remembers the last files you opened. Tap to reopen, even files stored outside the app on iOS. • Native iOS Document Picker: All-new native file open/save experience with proper security-scoped bookmarks, so files from iCloud Drive, the Files app, and external providers just work. • Remembers Your Last Conversion: The format you used last time is selected automatically the next time you launch. • Redesigned Action Toolbars: Grouped floating action clusters on every screen for cleaner reachability and a more focused workspace. • Organized Conversion Options: Conversion targets are now grouped into Visualizers, Transformers, Converters, and Generators, so the right option is always one tap away. • Sharper Code Editor: JetBrains Mono for code, refined line numbers, a streamlined keyboard toolbar, and a cleaner syntax highlighter across all formats. • Polished iOS Theme: Refreshed light and dark themes with better contrast, smoother surfaces, and tighter visual rhythm. • New Settings Screen: Centralized control over theme, auto-copy, conversion memory, line numbers, word wrap, and editor toolbar visibility. • Performance: Schema validation runs off the main thread, so larger files validate without freezing the UI.

Multi-Tab Support: Work with multiple JSON files simultaneously without switching windows. Open and edit files side by side in dedicated tabs, keeping your workflow smooth and organized. Direct File Access: Open JSON files directly from your device storage or file manager. No more import/export. Refreshed UI: A cleaner, more intuitive interface that gets out of your way. Improved layout, better readability, and a polished look that makes working with even complex JSON structures a breeze.
