DataLensia is a browser-based JSON toolkit designed for developers, data engineers, and anyone who works with structured data. It provides a suite of client-side tools to view, edit, validate, compare, transform, and visualize JSON — entirely in your browser, with no data ever sent to a server.

🚀 Quick Start

Upload your data: Drag and drop a JSON, CSV, or NDJSON file into any tool — or paste it directly into the editor.
Visualize: Explore the structure of your data using the interactive JSON Tree viewer.
Edit: Modify your JSON with full syntax highlighting and real-time validation in the JSON Editor.
Transform: Use the Transform Builder to visually map and reshape your data.
Build Pipelines: Connect multiple tools into automated workflows using Data Pipelines.
Convert: Export your data to CSV, YAML, SQL, and many other formats using the Convert Tool.
