Whether you are debugging API responses, editing configuration files, formatting complex nested objects, or converting between JSON and XML formats — this app provides everything you need in a single, fast, and reliable experience. THREE POWERFUL EDITING MODES Switch instantly between three professional editing views to work the way you prefer: Tree View — Navigate and edit your data in a collapsible, hierarchical tree structure. Expand, collapse, and modify nodes with a tap. See the full structure of your data at a glance and make precise edits without touching raw code. Source View — Work directly with raw code in a professional editor featuring syntax highlighting, line numbers, search, code folding, and adjustable font size. Toggle between Edit mode and View mode for safe browsing. List View — Browse key-value pairs in a clean, flat layout for quick scanning and editing. Perfect for finding specific values in large files. SMART SOURCE EDITOR The built-in code editor gives you a desktop-class experience on your mobile device: • Syntax highlighting for both JSON and XML with distinct colors for keys, values, strings, numbers, and brackets • Line numbers for precise navigation and reference • Search functionality to find any key, value, or text instantly • Code folding to collapse sections and focus on what matters • Adjustable font size for comfortable reading on any screen • Edit mode and View mode toggle for safe browsing ONE-TAP FORMAT & MINIFY Transform messy, minified, or unreadable data into clean, beautifully indented and formatted output with a single tap. Or minify formatted data for compact storage and network transmission. Works seamlessly for both JSON and XML files. JSON ↔ XML CONVERSION Convert any JSON file to XML or any XML file to JSON with one tap. The app automatically updates the file extension and preserves your data structure. This is perfect for developers working across different systems, APIs, and platforms that use different data formats. POWERFUL DATA OPERATIONS Take full control of your data with comprehensive editing tools: • Add new keys, values, objects, and arrays at any position • Delete single items or entire branches of your data tree • Rename keys without disrupting the structure • Duplicate nodes and entire subtrees for quick replication • Copy and paste data across documents • Multi-select mode for batch operations on multiple nodes at once — delete, move, or copy several items simultaneously FLEXIBLE IMPORT OPTIONS Open data from anywhere.
