AskCSV is a web-based tool that uses AI to let users ask natural language questions about their CSV or TSV files. It processes data entirely in the browser, ensuring privacy and security. Users can upload a file and receive instant insights, charts, and tables based on their queries. Example questions include finding top-selling products, identifying best customers, discovering frequently bought together items, and comparing marketing campaign ROI. The tool automatically generates the best chart type for each query. It supports files with headers in the first row and offers sample datasets for first-time users. AskCSV is designed for quick, secure data analysis without server uploads.
