Auto-formats and enhances JSON in your browser with advanced search, themes, data pinning, and robust large file support. Does your browser struggle to open large JSON files? Are you tired of switching between tabs to compare data? Meet Lens, the next-generation JSON Viewer designed for modern developers. Lens replaces raw data with a stunning, interactive, and high-performance data explorer. Whether you are debugging an API, analyzing 10MB+ datasets, or comparing production vs. staging responses, Lens makes it effortless. 🚀 EXCLUSIVE: MULTI-FILE SYNC & COMPARE Most viewers only handle one file at a time. Lens allows you to load multiple JSON files side-by-side in a single window. • Synchronized Navigation: Expanding a nested key (like "user.address") in one file automatically expands it in ALL open files. • Contextual Comparison: Instantly spot differences in structure between environments without manually clicking through deep nesting on every file. ⚡ UNMATCHED PERFORMANCE Lens includes a dedicated "Performance Mode" with virtual scrolling logic. • Zero Lag: Handles massive files (10MB+) and heavy arrays without freezing your browser. • Smart Loading: Automatically detects file size and optimizes rendering to ensure the viewer loads instantly. 🛠️ DEVELOPER TOOLKIT Lens is packed with tools to speed up your workflow: • TypeScript Generator: One-click "TS" button generates full TypeScript Interfaces for your data. • Breadcrumbs: Hover over any item to see its exact path (e.g., "response.users[0].id") and click to jump there. • Table View: Transform arrays of objects into a sortable, filterable spreadsheet grid. • Graphing: Automatically detects URLs and renders them as clickable links. 🔍 ADVANCED SEARCH Stop using basic Ctrl+F. Lens offers a powerful search engine: • Key:Value Logic: Search specifically for "status:200" or "id:123". • Boolean Operators: Use "+" to find items matching multiple terms (e.g., "+error +fatal"). • Scoped Search: Limit results to just Keys, just Values, or "Filter Results" to hide everything that doesn't match. 🎨 BEAUTIFUL & CUSTOMIZABLE • 12 Pro Themes: Includes Midnight Blue, Monokai, GitHub Light, Solarized, and more. • 9 Coding Fonts: Customize your view with Fira Code, JetBrains Mono, Inter, and others. • Glassmorphism UI: A modern, distraction-free interface with sticky headers. 📂 FLEXIBLE INPUTS • Auto-detects JSON on web pages. • Drag & drop local .json files. • Paste text directly from the clipboard. • Import from URL. 🔒 PRIVACY FOCUSED Lens works entirely offline within your browser. Your data is parsed locally and is never sent to any server or third party. CONTROLS SHORTCUTS: • "f" : Focus Search • "e" : Expand All • "c" : Collapse All • "Ctrl + Click" : Recursive Expand/Collapse • "?" : Open Help Menu Upgrade your workflow with Lens today.
