Stop staring at raw brackets. Start understanding your data.
As part of my work, I often find myself dealing and wrestling with large JSON files to review API executions, LLM responses, and other data for debugging, troubleshooting, analysis, or simply to make sense of it all. Constantly switching between multiple websites, many of which are cluttered and filled with ads started to feel inefficient and frustrating.
So I decided to solve the problem myself. And while I was building it, like any true indie maker, I thought why not just launch it? That’s how this came to be.
JSON Kit is a free, easy to use visualization suite designed to make working with complex JSON structures intuitive and beautiful. Unlike other tools that require server uploads, JSON Kit runs entirely in your browser, ensuring your sensitive keys and customer data never leave your machine.
✨ Key Features:
🕸 Interactive Graph Engine: Transform large JSON files into navigable, zoomable node trees. Search, expand, and isolate specific data paths instantly.
🗺 Mini View Finder: Never get lost in deep data again. Our persistent Minimap provides a high-level aerial view of your entire JSON structure, letting you navigate to distant nodes with a single click.
🔦 Smart Path Highlighting: Instantly trace data lineage. Hover over any node to illuminate the exact path back to the root, making it effortless to debug complex nesting and understand object relationships.
⚡️ Structural Diffing: Debug faster by comparing two JSON files side-by-side. See exactly what was added, removed, or modified with color-coded visual graphs and line-by-line code diffs.
🔄 Smart Conversion: Convert nested JSON into flattened CSV, XML, or YAML. Our smart flattener preserves parent context, making it perfect for exporting NoSQL data to spreadsheets.
🎨 Stunning UI: Built with a modern glassmorphic interface featuring 6 distinct themes (including Night Vision, Synthwave, and Nebula) to match your aesthetic.
🔒 Local & Safe: No API keys required. No server uploads. Your data processes locally in memory, making it safe for production logs and sensitive config files. New features that on the roadmap might require server uploads and processing.
📸 Export Ready: Generate high-res PNGs, SVGs, or PDFs of your data architecture for documentation and presentations.
