CSVLens Overview
CSVLens revolutionizes CSV data analysis by combining the power of AI with a privacy-first, local processing approach. Designed for data analysts, business users, and anyone needing quick insights, it eliminates the need for complex tools or SQL knowledge. Users can simply drag and drop massive CSV files, which load in seconds, not hours, thanks to local processing with DuckDB WASM. Then, by typing natural language questions, users receive instant answers and auto-generated charts, making data exploration intuitive and efficient.
How to use CSVLens
Using CSVLens is straightforward and requires no technical expertise. First, simply drag and drop your CSV file(s) directly into the browser interface; your data remains local and is never uploaded. Next, type your questions in plain English, such as "What's the average order value?" or "Show me monthly trends." The AI will interpret your query and generate the appropriate SQL. Finally, CSVLens provides instant answers with automatically generated charts, which you can pin to build custom dashboards in seconds.
