An AI Agent For Microsoft Excel That Keeps Your Workbooks Current

Spreadsheets run a lot of small businesses and updating them is tedious. The agent opens your workbooks in OneDrive or SharePoint, makes the edits you describe and explains what it changed.

What Your Agent Does In Microsoft Excel

  • Updates Sheets From Messages

    Tell it that the Harper order shipped on Tuesday and it finds the row in your tracker and fills in the date and status.

  • Fixes Formulas And Layouts

    It finds a SUM that skips a row or a column of dates stored as text, fixes it and tells you which cells it touched.

  • Builds Summaries

    Point it at a sales workbook and it adds a summary sheet with totals by region and month, leaving the raw data alone.

Ask In Your Own Words

Type it in any project chat, or send it from your phone. Your agent works in Microsoft Excel for you, with your own login, and reports back in the thread.

  • Update the shipping tracker: the Harper order went out on Tuesday.
  • Why does the total on the Budget sheet not match the monthly tabs?
  • Add a summary sheet with sales by region from the Q-sales workbook.

Questions About Microsoft Excel And Your Agents

Can the agent open any workbook on my computer?

No. It works with workbooks in the OneDrive or SharePoint account you connected, not files that live only on your computer.

Will it overwrite my data?

It says which cells it will change first, keeps your original values in a note and waits for your OK before overwriting existing data.

Does my agent see my Microsoft Excel password?

No. Your Microsoft Excel login stays in your Vault, a safe your agents can use but never read. You can remove an agent’s access, or disconnect Microsoft Excel, at any time in Settings.
