AskCSV

AskCSV analyzes a spreadsheet entirely in the browser, letting users ask questions about a CSV, TSV, or Excel file and receive charts based on the data. The tool is presented for anyone who works with spreadsheets and wants to explore numbers interactively without uploading the file. It keeps the AI's view of the data minimal and avoids sending the full file to remote servers.

AskCSV opens the file in the browser and runs queries locally, ensuring the file isn’t uploaded. It supports reading CSV, Excel (.xlsx, every sheet) and pasted cells, with no live database or Google Sheets connections yet. The interface allows users to drop a file or try a sample to see how questions yield pivots and charts.

The system explains that the AI selects questions to ask the data and the database answers them. Charts are drawn from actual query results and every number comes from a query that the user can read. The workflow emphasizes a transparent, query-driven approach where results are grounded in SQL and in-browser computation.

The data handling policy emphasizes that files stay in the browser and that the AI sees only shared columns, a limited sample, and the relevant query results. Users can review sample rows, turn columns on or off, and delete data locally; the browser processes all requests and the server handles the planning and explanation step.
