Summary

Microsoft Copilot is an AI assistant inside Excel that writes formulas, builds standard charts and pivot tables, and needs a Microsoft 365 subscription. Better Analyst (formerly Formula Bot) works across Excel, Google Sheets, CSVs, PDFs and databases, and adds interactive dashboards, SQL generation and scheduled workflows. Pick Copilot if your work never leaves Excel.

The short version

Microsoft Copilot is an AI assistant built into Excel. It generates formulas, creates standard Excel charts, builds pivot tables, and answers basic data questions — but it only works inside Excel, requires a Microsoft 365 subscription, and costs $30/user/month on top of that.

Better Analyst goes further. It supports Excel, Google Sheets, CSVs, PDFs, and images. It connects directly to databases like PostgreSQL, Supabase, BigQuery, and Snowflake. It generates interactive, customizable charts — not just the 12 standard Excel types — plus AI-generated dashboards with scheduled auto-refresh. Add SQL generation, automated workflows, team workspaces, and embeddable analytics, with plans starting at $20/month and no other subscriptions required.

If your work begins and ends inside Excel and you already pay for Microsoft 365, Copilot is a solid choice. If you work with multiple file types, need live data connectors, want interactive visualizations, or need to automate recurring reports, Better Analyst covers significantly more ground.

Where Better Analyst pulls ahead

No Microsoft lock-in

Better Analyst works in any browser with any spreadsheet tool — Excel, Google Sheets, CSV, databases, or just a question. Copilot only works inside the Microsoft ecosystem.

10+ live data connectors

Connect directly to PostgreSQL, Supabase, MySQL, BigQuery, Snowflake, Google Analytics, Search Console, Google Ads, and more (Meta Ads is coming soon). Copilot can only analyze files you open in Excel.

Automated workflows & reports

Schedule tasks that run daily, weekly, or monthly — with auto-refreshing dashboards and email delivery. Copilot has no automation layer.

White-label embeddable analytics

Embed AI-powered analytics directly into your product with custom branding and row-level security. Copilot offers no embeddable solution.

Broader AI toolkit

Beyond formulas and charts, get SQL generation, regex, VBA, Google Apps Script, sentiment analysis, data enrichment, and PDF extraction — all in one place.

Transparent, standalone pricing

One subscription, no prerequisites. Copilot requires a separate Microsoft 365 license ($12.50–57/user/mo) before you can even add the $30/user/mo Copilot license.

Where Copilot has the edge

We believe in honest comparisons. Here’s where Copilot does well.

Deep Excel integration

Copilot lives inside Excel and can directly edit cells, apply formatting, and modify workbooks in place. Better Analyst works alongside your spreadsheets rather than inside them.

Microsoft 365 ecosystem

If your team already pays for Microsoft 365 E5, Copilot works across Word, PowerPoint, Outlook, and Teams — not just Excel.

Offline partial support

Copilot can work with locally stored Excel files. Better Analyst requires an internet connection.

Known Copilot for Excel limitations

  • Accuracy Warnings: Microsoft themselves warn against using the COPILOT function "for any task requiring accuracy or reproducibility." Complex multi-step reasoning can produce subtly wrong conclusions.
  • Usage Caps: The in-cell COPILOT function is capped at 100 calls per 10 minutes and 300 per hour. Dates are returned as text, not native Excel date format.
  • Microsoft 365 Required: Copilot is an add-on to Microsoft 365 — you cannot buy it standalone. If you don't already have Microsoft 365, the total cost is $42.50–87/user/month.
  • No External Data Connectors: Copilot only works with data already in your Excel file. It cannot connect to databases, APIs, or analytics platforms.
  • No Automation: There is no way to schedule recurring analyses, auto-refresh dashboards, or send email reports with Copilot.
  • Excel Only: Copilot does not support Google Sheets, CSV-only workflows, or any spreadsheet tool outside the Microsoft ecosystem.

Frequently asked questions

Is Formula Bot a replacement for Microsoft Copilot?
For spreadsheet and data analysis tasks — yes, and then some. Formula Bot covers everything Copilot does in Excel (formulas, charts, data Q&A) while adding database connectors, automation workflows, white-label embeds, and tools like SQL generation and sentiment analysis. If you need Copilot for Word, Outlook, or Teams, those are separate use cases Formula Bot does not cover.
Do I need Microsoft 365 to use Formula Bot?
No. Formula Bot works in any modern browser. You can upload Excel files, CSVs, or PDFs, connect to databases, or just type a question. There are no prerequisites or additional subscriptions required.
How does pricing actually compare?
Formula Bot paid plans start at $20/month billed annually ($30 monthly) for Pro, with unlimited chat subject to fair use and no other subscriptions required. Team is $149/month for a shared workspace with 5 people included, $15/month per extra person. Microsoft Copilot costs $30/user/month but requires an existing Microsoft 365 subscription ($12.50–57/user/month depending on plan). For a single business user, Copilot can cost $42.50–87/month total versus $20/month for Formula Bot.
Can Formula Bot connect to my database?
Yes. Formula Bot supports direct connections to PostgreSQL, Supabase, MySQL, Microsoft SQL Server, Google BigQuery, and Snowflake. You can query your data in natural language without writing SQL. Copilot for Excel cannot connect to external databases.
Is Formula Bot accurate for data analysis?
Formula Bot executes actual code (Python, SQL) against your data in a secure sandbox — it does not guess or hallucinate numbers. Microsoft Copilot has documented accuracy limitations and Microsoft themselves warn against using certain features "for any task requiring accuracy or reproducibility."
Can I automate recurring reports?
Yes. Formula Bot lets you build tasks (reusable analysis workflows) and schedule them to run daily, weekly, or monthly — with results delivered via email or auto-refreshing dashboards. Copilot has no built-in automation or scheduling capabilities.
Does Copilot work with Google Sheets?
No. Microsoft Copilot only works with Excel. Formula Bot supports both Excel and Google Sheets with dedicated add-ons for each, plus a standalone web app that works with any file format.
Can I embed Formula Bot analytics in my own product?
Yes. The Formula Bot Team plan includes an embedded AI chat with custom colors, row-level security, and single-iframe integration, and Enterprise adds unlimited white-label embeds. Copilot has no embeddable offering.
