JSON

JSON is a lightweight viewer and editor that makes complex JSON files easy to read and edit on your Android device. If you often inspect API responses, adjust configuration files for apps or games, or need to patch nested settings without a PC, JSON provides a compact tree editor, search and filter tools, and a raw text mode for bulk copy and paste. Files can be opened directly from file managers or email attachments, so small fixes and quick debugging can be done on the go. The app focuses on practical mobile workflows for engineers and power users.

Key Features

⭐ Intuitive tree editor that displays deeply nested structures with collapsible and expandable nodes for clear navigation.

⭐ Smart breadcrumb navigation that shows your current position and lets you jump to parent levels with a single tap.

⭐ Search and filter capabilities to highlight and edit the exact keys and values you need in large JSON datasets.

⭐ Open JSON files directly from file managers or email attachments using intents for fast on-device access.

⭐ RAW mode for viewing formatted text and copying large blocks of JSON with one tap.

Advantages

✅ Quickly inspect JSON API responses and configuration data without a laptop, ideal for on-the-go debugging.

✅ Make edits to app or game configuration files directly on your phone, saving time when a PC isn’t available.

✅ Lightweight and stable toolset that focuses on core JSON editing functions without unnecessary complexity.

Disadvantages

❎ The free version includes ads and some capabilities are locked behind the Pro upgrade.

❎ Working with very large or extremely deep JSON structures can be cramped on smaller screens and may feel awkward compared to a desktop editor.
