Lens - Advanced JSON Viewer

About

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.
