Giant JSON: Huge File Viewer

Finally, a JSON viewer that actually works with huge files.

Giant JSON Viewer is built for developers and data analysts who need to handle massive JSON datasets (multi-gigabyte logs, database dumps, exports) directly on their Android device.

While other apps crash with files larger than 50MB, Giant JSON Viewer uses a high-performance native core (powered by Rust) to open Multi-Gigabyte files efficiently.

🔒 PRIVATE & SECURE
Your data clearly matters. We operate with a strict Zero-Data-Exfiltration policy.
• Your files never leave your device.
• All analysis, search, and export happens locally.
• No cloud uploads, no hidden servers.
• GenAI Regex calls the AI only to generate patterns; your file content remains 100% offline.

🚀 EXTREME PERFORMANCE & SMART LOADING
• Massive File Support: Designed for datasets that break standard viewers.
• Smart Indexing: The app builds an index on the first load to ensure rapid navigation and searching. (Note: Initial indexing may take time for huge files).
• Memory Efficient: Engineered to prevent Out-Of-Memory crashes.

🛠️ PROFESSIONAL TOOLKIT
Turn your smartphone into a serious developer workstation:
• Schema Analysis: Automatically scan huge files to detect field types and structure.
• SQL & CSV Export: Convert nested JSON data into SQL queries (create table/insert) or CSV files for Excel/Sheets.
• Smart Search: Find any value instantly with rapid text search.
• GenAI Regex Builder: Describe what you want to find (e.g., "email addresses"), and our AI generates the regex pattern for you.
• JSON Path Support: Deep link to specific nodes.

✨ 3 POWERFUL VIEW MODES
1. Browser Mode: Best for massive files. Stream through gigabytes of data like a news feed.
2. Structure Mode: Visualize your JSON structure (like a graph). Great for understanding the shape of data (Note: Shows structure only, not values).
3. Text Mode: View raw JSON text with syntax highlighting (Read-Only).

🔍 ADVANCED FEATURES
• Bookmarks: Save interesting locations in invalid or massive files.
• Unescape & Prettify: Fix ugly serialized JSON strings with one tap.
• Hide Paths: Declutter your view by hiding irrelevant arrays or objects.
• Schema Validation: Validate your JSON files against a schema file.

Supported Formats:
• .json (Standard)
• .jsonl / .ndjson (Newline Delimited)
• .txt (with JSON content)
