Copilot for Excel Alternative
If you're paying $30/seat/month for Microsoft 365 Copilot but your real data lives in Google Sheets, Postgres, or Stripe — and you can't ask Copilot "what's a competitor's traffic?" without buying a separate tool — this is the cross-source, cross-model alternative. OnlySearch connects to Excel and Google Sheets and Postgres and BigQuery and Stripe in the same chat; ships built-in market intelligence Copilot doesn't have; runs every major model (GPT, Claude, Gemini, DeepSeek, local) with bring-your-own-key (not Microsoft-only); and includes a coding agent that opens GitHub PRs so the analysis ships as code, not just a spreadsheet. Keep Copilot for in-Excel formulas and PowerPoint generation; add OnlySearch for cross-source data work.

Why people search for Microsoft 365 Copilot alternatives
- 1
You bought M365 Copilot last quarter and discovered only after that the SKU you actually need is a tier up. The bill keeps moving.
- 2
You wanted to compare your output on GPT-5 vs Claude vs Gemini for one task — Copilot only runs Microsoft's models, no dropdown, no BYOK.
- 3
You're paying $30/seat/month whether you use Copilot heavily or not — usage doesn't change the line item.
- 4
You asked Copilot "what's a competitor's traffic trend?" and got a polite shrug. Copilot ships no market intelligence.
- 5
Half your data lives in Google Sheets and Stripe, and Copilot can't reach either without Power Query workarounds.
- 6
You wrote one cross-source DAX query that took two days and still doesn't refresh reliably.
- 7
You finished the analysis and now need to update three meta tags in your repo — that means a separate GitHub Copilot license and a context switch.

When to stay with Microsoft 365 Copilot
We’re not the right tool for everyone. Here’s when Microsoft 365 Copilotis the better choice — and we’d recommend it.
- Your entire stack is Microsoft 365 (Excel, Outlook, Teams, SharePoint) and most of your data legitimately lives in those apps.
- Most of your work is in-Excel formula composition and pivot-table refresh — the kind of work Copilot's in-app integration is genuinely best at.
- Your IT team has already negotiated and deployed Copilot enterprise-wide and the per-seat cost is amortized across other apps you use.
- You're a finance or operations lead who needs answers inline in the spreadsheet, not in a separate tool.

Common questions about Microsoft 365 Copilot alternatives
Is OnlySearch a Microsoft Copilot alternative?
For data analysis, cross-source workflows, model choice, and shipping code — yes. For in-Excel formatting, in-PowerPoint generation, or in-Outlook drafting, Copilot remains the right tool because it lives inside the Office apps. Many teams keep Copilot for in-app productivity and add OnlySearch for analysis-and-ship workflows.
Can OnlySearch open .xlsx files?
Yes. Upload an Excel file or connect a OneDrive/SharePoint folder. OnlySearch reads sheets, headers, and named ranges, and answers questions in plain English without writing formulas.
Does OnlySearch support models other than Microsoft's?
Yes. OnlySearch supports OpenAI's GPT family, Anthropic's Claude, Google Gemini, DeepSeek, Qwen, and any OpenAI-compatible endpoint, with bring-your-own API key. Copilot is locked to Microsoft's bundled models.
What built-in market data does OnlySearch ship that Copilot doesn't?
Web traffic by country and source for any domain, keyword volume and difficulty, backlink profiles, similar-site and competitor discovery, brand mentions, and AI-assistant visibility. Copilot ships none of this — its data is whatever's already in your M365 tenant.
Can OnlySearch write code and push to GitHub?
Yes. OnlySearch's coding agent connects to GitHub, edits files, runs CI, and opens pull requests. Copilot for Excel doesn't ship to code — that's a separate Microsoft product (GitHub Copilot) you license additionally.
Is OnlySearch free?
Yes. The free plan resets weekly and includes the full data agent — connect databases, spreadsheets, and APIs, generate charts, and ask follow-up questions. Paid plans (Starter $59/mo, Pro $159/mo, Business $299/mo) raise weekly credit limits and unlock add-on packs.
Will OnlySearch train on my data?
No. Queries, files, and connected sources stay yours. We don't train on customer data and we never will. Sensitive workflows stay scoped to your account.
