Getting Started
Follow these steps to start using Cellify in Excel:
Install from Microsoft AppSource
Open Excel → Insert → Add-ins → Get Add-ins → search
Cellify → click Add. The add-in appears in your Home ribbon.
Sign in with your Microsoft account
Open the Cellify panel. Click Sign In and authenticate with the same Microsoft
account you use in Excel/Office 365. This links your Free or PRO plan to your identity.
Type a natural language command
Click on any cell, then type a command in the Cellify chat, for example:
“Create a monthly sales table with 3 products and calculate totals.”
Cellify translates it into Excel actions automatically.
Review the result
Cellify applies changes directly to your sheet. Check the result before saving.
The AI can make mistakes — always keep a backup of important files.
Tip: The Free plan includes 50 AI actions per month (chat-only questions are free). To get more,
upgrade to PRO via Microsoft AppSource or
contact us for early access.

Yes. Like all AI systems, Cellify can produce incorrect formulas, wrong values, or
unexpected formatting. Always review AI-generated changes before
saving critical files. Keep backups of important workbooks. Cellify is not liable
for data loss caused by AI output — see
Terms of Service Section 4 for the full disclaimer.

Once the AI writes data, formulas, or charts into your sheet, that content works
offline like any normal Excel content.
Cellify works on Excel for Windows (Microsoft 365),
Excel for macOS (Microsoft 365), and
Excel Online (browser). It does not support Excel 2019 or older
standalone versions that lack Office.js Add-in support.
