kasipa (formerly deepsheet)
kasipa (formerly deepsheet) is a browser-based data visualization tool that turns spreadsheets into charts and analysis through plain-language questions. Upload a CSV, Excel file, or connect a Google Sheet, describe what you want to see, and get interactive Plotly charts without installing desktop software.
The product runs analysis locally in your browser using WebAssembly, so your spreadsheet data stays on your device during chart generation. You can start from the homepage without creating an account, then refine results with follow-up messages until the chart matches what you need.
Beyond one-off charts, kasipa includes a community showcase where users publish visualizations built from public-interest datasets. The tool also supports multi-sheet Excel workbooks, Google Sheets links, and dedicated CSV and Excel to chart landing pages for quick uploads.
Creator Dylan Castillo built kasipa for analysts, researchers, and business users who want spreadsheet insights without writing code or switching between multiple tools.
