About this app

JSON Analyzer is a fast, lightweight tool for developers and anyone who works with JSON data. Parse, format, and explore JSON structures instantly — right on your phone.

🌳 Core Features

• Pretty Print & Minify — Format messy JSON into readable form or compress it into a single line with one tap.
• JSON Path — Tap any node to copy its full JSON path (e.g. $.users[0].name). Perfect for debugging.
• Search — Find any key or value instantly, even in deeply nested structures.

🌐 HTTP Request Tester
• Send GET, POST, PUT, PATCH, and DELETE requests directly from the app.
• Add custom headers and JSON request bodies.
• View response status, headers, and body — then jump straight into the tree viewer to explore the result.
• Full request history with search and favorites.

⚡ Productivity
• Open .json files from your file manager or receive shared JSON from other apps.
• Copy values, paths, or entire nodes to clipboard.
• Share or save formatted JSON as a file.
• URL autocomplete and header suggestions from your history.
• Dark and light themes.

🔒 Privacy First
