ExcelMaster vs kasipa (formerly deepsheet)

Windows desktop Excel can run an autonomous agent add-in that plans multi-step spreadsheet work from plain-language prompts. ExcelMaster reads workbook structure across sheets, writes formulas or VBA/Python, executes changes inside Excel, and shows each step in a live sidebar. Finance teams, analysts, and operations staff use it for month-end close, variance reports, data cleanup, and macro automation without leaving the file.

Where Copilot and ChatGPT stop at suggested snippets, ExcelMaster closes the loop inside the workbook. It maps real sheet names, merged cells, and cross-sheet references before generating code, runs VBA or Python locally, verifies output, and retries on errors with automatic rollback. The product site cites internal benchmarks where template-style chat code needed far more edit rounds than agent execution on real user cases.

Dedicated Formula Assistant, VBA Assistant, and Cell AI modules cover formula dialogue, macro automation, and per-cell tasks like classification, keyword extraction, format conversion, sentiment scoring, and translation. Files stay on your machine; only relevant cell content goes to AI models when analysis is needed.

ExcelMaster requires Excel 2016 or later on Windows 10/11 (desktop, not Excel Online). Subscription plans start at $9.99 per month with a 3-day trial, and one-time credit packs are sold separately. The site also hosts free browser utilities for Excel, PDF, and Word conversions.

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.
