Json Genie (Viewer & Editor)

Json Genie (Viewer & Editor) is the fastest JSON viewer and editor for Android, designed to make working with JSON files effortless whether you're checking API responses or editing complex configurations.

Open JSON and JSONC files from multiple sources — your device's file system, shared content, pasted text, direct URLs, or supported archives. Create documents from scratch or load existing ones instantly. The clean tree view makes navigating deeply nested objects and arrays intuitive, even for users new to JSON. No confusing interfaces or unnecessary complexity — just straightforward editing that works the way you'd expect.

Edit JSON with confidence. Add, remove, reorder, and update entries with a few taps. Search for specific keys and values across your entire document or within individual sections. Open multiple files simultaneously in tabs and switch between them seamlessly. Whether you're adjusting config files, reviewing API responses, or formatting exported data, the app adapts to your workflow without getting in your way.

Format and optimize your JSON however you need. Pretty-print for readability, minify for compact storage, or sort keys alphabetically for consistency. Preview changes before you save and export as text or a proper file. The app handles both standard JSON and JSON with comments (JSONC), covering virtually every use case you'll encounter.

Performance matters, especially on mobile. Json Genie stays responsive and fast even with large, complex documents. The interface automatically adjusts to your system settings — choose between light, dark, or system appearance for comfortable viewing in any lighting condition. Multi-language support ensures accessibility for users worldwide.

View detailed document information including source location, detected format, and file metadata. Rest assured your unsaved changes are protected with smart handling that prevents accidental data loss. Share your work easily — export as plain text for quick sharing or as a file for permanent storage.

Whether you're a developer working with APIs, a system administrator managing configurations, or someone who occasionally needs to inspect or edit JSON data, Json Genie (Viewer & Editor) provides the speed, clarity, and features you need to get the job done comfortably on Android.
