VisiLens solves the dilemma between slow Excel and complex Pandas code. It is a local-first, zero-config data explorer. What's different: Speed & Scale: Opens 1M+ rows in ~1.7s by streaming data from the VisiData engine. Privacy: Runs 100% locally via FastAPI/React. Your data never leaves your machine. Usability: Provides a modern, mouse-friendly web GUI (sorting, filtering) for quick exploration without needing to memorize CLI shortcuts.

Hi Hunters! 👋 I'm the creator of VisiLens. I built this tool out of frustration. As a developer working with data, I constantly faced a dilemma: Excel freezes or crashes on files larger than 50MB. Pandas/Jupyter requires writing code just to "take a quick look." VisiData (CLI) is incredibly fast, but I could never remember the keyboard shortcuts. So, I built VisiLens to bridge the gap. It combines the raw, C-speed engine of VisiData with a modern, virtualized Web GUI. ✨ What makes it different? It's Fast: Opens 1M rows in ~1.7s (streaming architecture). It's Private: Runs a local Python server. Your data never leaves your machine. It's Universal: Supports CSV, Parquet, Excel, JSON, and more. It is 100% Open Source. If you like the project or eager for more updates, please click a star! I'd love to hear your feedback on the UX! Specifically, are there any Excel features you miss the most? Happy exploring! 🚀
