Array Assistant vs Coefficient

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.

Coefficient is a spreadsheet add-on for Google Sheets and Microsoft Excel that connects live business data from CRMs, warehouses, marketing platforms, and accounting tools without SQL or engineering tickets. It installs as a sidebar inside your spreadsheet and lets you pull, refresh, and write data back to systems like Salesforce, HubSpot, Snowflake, and QuickBooks. GPT Copilot adds plain-English tools for cleaning data, building pivot tables, generating charts, and connecting new sources by description.

Where dedicated BI tools like Tableau or Looker need trained developers and charge per viewer, Coefficient keeps the build surface in the spreadsheet your team already uses. The newer AI Dashboards feature turns any sheet into a shareable web dashboard with prompt-based editing, drill-down to source records, and row-level security, all without a separate BI license for viewers.

Finance, revenue operations, marketing, and analytics teams use Coefficient to replace copy-paste reporting with scheduled refreshes, Slack alerts, and two-way sync. The company reports 700,000 users and integration with 150+ business systems. Excel support covers data imports across connectors, while Alerts and GPT Copilot are still rolling out on the desktop add-in.
