TwistlyCells Review (2026): Pricing, Features & Honest Verdict

TLDR

TwistlyCells (formerly ChatGPT for Excel) adds 8 AI-powered formulas to Microsoft Excel for content generation, data extraction, translation, and cleanup. Useful but niche. Best for: Excel users who want AI without Copilot pricing. Price: from $8.99/user/month. Rating: 6.9/10

What is TwistlyCells?

ChatGPT for Excel is a Microsoft Excel add-in built by Apps Do Wonders LLC under the TwistlyCells brand. It adds eight custom AI formulas to your spreadsheet that let you generate text, extract data from messy cells, translate content, and clean up formatting without leaving Excel. Think of it as bringing ChatGPT into your cells as native functions.

The add-in launched on Product Hunt in March 2026 and supports multiple AI models including GPT-5 mini, GPT-4o, Claude 3.5 Sonnet, and Claude 3 Opus. You install it from Microsoft AppSource and start typing formulas like =AI.ASK() or =AI.EXTRACT() in any cell.

The Eight AI Formulas

Content Generation

AI.ASK lets you ask questions and generate text directly in cells. AI.TABLE creates structured tables from prompts. AI.LIST generates lists. These work well for drafting product descriptions, generating test data, or creating content outlines. The output quality depends on which model you pick, with GPT-5 mini delivering the best results.

Data Extraction and Cleanup

AI.EXTRACT pulls emails, dates, prices, and other structured data from messy text cells. AI.FORMAT standardizes formatting across inconsistent data. AI.FILL predicts and fills cells based on patterns. These are the most genuinely useful functions. If you spend hours cleaning imported CSV files or standardizing address formats, these formulas save real time.

Translation and Summarization

AI.TRANSLATE handles multi-language translation across cells. AI.SUMMARIZE condenses long text blocks. Both work reliably for common languages, though specialized terminology can trip up the translation function.

Pricing Breakdown

The free trial gives you access to all eight formulas with limited credits. Once those run out, you choose between two paid approaches.

Starter ($8.99/user/month): Includes $3 of AI credits monthly. TwistlyCells handles the AI billing, so you never need to set up an OpenAI account. Simple but the credits disappear fast with heavy use.

Pro (lower monthly fee): You connect your own OpenAI API key and pay OpenAI directly per token. Better economics for heavy users since you avoid the markup on credits.

Team: Multi-user management with centralized billing. Pricing varies by team size.

Annual billing saves 36%. For comparison, Microsoft Copilot for Excel costs $30/user/month but does much more. If all you need are these specific AI formulas, TwistlyCells is cheaper. If you want full AI integration across Word, PowerPoint, and Outlook too, Copilot wins on value.

What Works Well

The formulas integrate cleanly into Excel workflows. There is no context switching to a separate AI tool. You type a formula, it returns results in the cell. For data cleaning tasks specifically, AI.EXTRACT and AI.FORMAT are genuinely faster than writing VBA scripts or manual cleanup.

Supporting multiple AI models is a smart move. You can pick GPT-5 for quality-critical tasks and GPT-3.5 Turbo for bulk operations where speed and cost matter more than perfection.

What Falls Short

The biggest issue is a destructive one: inserting AI content can overwrite existing cell data without warning, and there is no undo. One reviewer reported losing previous work this way. For a tool that sits inside a spreadsheet full of data, this is unacceptable.

The interface is not intuitive. The add-in panel feels clunky, and figuring out the right formula syntax takes trial and error. Better documentation and in-cell autocomplete would help.

Excel-only support is a limitation. Many teams split work between Excel and Google Sheets. Competitors like Numerous.ai support both platforms.

Alternatives

Microsoft Copilot

The obvious comparison. Copilot is built natively into Excel with deeper integration, natural language queries, and works across all Microsoft 365 apps. At $30/user/month it costs 3x more, but the capability gap is significant.

Numerous.ai

Works in both Excel and Google Sheets. Uses a =NUM.AI() function approach similar to TwistlyCells. Starts at $10/month. Better platform coverage but fewer specialized formulas.

SheetGod

Converts plain English to Excel formulas, VBA macros, and regex patterns. More focused on formula generation than content generation. Different use case but worth considering if your pain point is writing complex formulas.

The Bottom Line

ChatGPT for Excel fills a specific gap: bringing AI capabilities into Excel cells at a fraction of Copilot pricing. The data extraction and cleanup formulas genuinely save time. But the destructive overwrite bug, Excel-only limitation, and clunky interface hold it back. If Microsoft Copilot is too expensive for your team and you mostly need AI for data cleanup tasks in Excel, this works. For anything more ambitious, the $30/month Copilot investment pays for itself.

FAQ

Does ChatGPT for Excel work with Google Sheets?

No. TwistlyCells is Excel-only, available through Microsoft AppSource. For Google Sheets, look at Numerous.ai or GPT for Sheets.

How is this different from Microsoft Copilot?

Copilot is built into Microsoft 365 at $30/user/month with deep integration across all Office apps. ChatGPT for Excel is a third-party add-in at $8.99/month with specific AI formulas. Copilot is more powerful but costs 3x more.

What AI models does it support?

GPT-5 mini, GPT-5 nano, GPT-4o, GPT-4 Turbo, GPT-3.5 Turbo, Claude 3.5 Sonnet, Claude 3 Opus, and Claude 3 Haiku.

Can it overwrite my data?

Yes. Inserting AI content from the add-in can replace existing cell data without undo. Always save before running AI operations.
