Array Assistant vs kasipa (formerly deepsheet)

Array Assistant is a Microsoft Excel add-in that puts nine AI helpers inside your workbook. You install the plugin, open a sheet, and run tools for formula writing, data cleanup, summaries, list building, trend spotting, and text drafting without leaving Excel.

Most spreadsheet add-ins charge from day one or hide everything behind one chat box. Array Assistant splits work into named tools like Formula Generator, Data Cleaner, and Trend Analyzer, each tuned to a spreadsheet task. The Basic plan stays free at 200 requests per month, and the site publishes solution pages for investment banking, private equity, accounting, venture capital, consulting, real estate, and insurance teams rather than pitching a generic assistant.

The plugin suits analysts, students, and business professionals who live in Excel and want faster formula work, cleaner columns, and quick text inside cells. Corporate teams can request custom pricing when they need unlimited usage across employees.

kasipa (formerly deepsheet) turns CSV, Excel, or Google Sheets into interactive Plotly charts when you ask questions in plain English. Upload a spreadsheet or paste a Google Sheets link, describe the chart you want, and refine the result with follow-up messages until it matches what you need.

Unlike cloud analytics suites that upload your files to remote servers, kasipa runs spreadsheet parsing and chart generation locally in the browser via WebAssembly. That local-first approach suits quick one-off visualizations where you do not want data leaving your device, though team database connections and shared Explores sit behind the paid Professional tier.

You can start charting without creating an account, and multi-sheet Excel workbooks let you pick which tab to visualize. kasipa also hosts a community showcase where users publish charts built from public-interest datasets, plus dedicated CSV and Excel to chart landing pages for fast uploads.

Creator Dylan Castillo built kasipa for analysts, researchers, and business users who want spreadsheet insights without writing code or juggling separate charting tools.
