Array Assistant vs Sheet Copilot

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.

Install Sheet Copilot from the Google Workspace Marketplace and you get a chat sidebar inside Google Sheets. Describe the outcome you want in plain language, connect your OpenAI API key, and the add-on uses GPT-4 to build formulas, apply formatting, and create charts while you watch each step land in the spreadsheet.

Most spreadsheet copilots either sit outside Google Sheets or bundle model costs into a subscription. Sheet Copilot keeps you in the sheet, charges nothing for the add-on during its beta period on the marketplace listing, and sends model usage to your own OpenAI account instead of wrapping it in vendor pricing.

The marketplace listing shows more than 83,000 installations, labels pricing as free of charge with paid features, and was last updated in September 2024. Your OpenAI key stays in your Google account per the listing, and support runs through [email protected]. The sheetcopilot.ai marketing site links to the same marketplace install button.

Finance teams, analysts, and educators who picked Google Sheets for Excel-style work can offload routine formulas, table cleanup, and quick charts without opening another analytics app.
