How To Update Spreadsheets With AI

For cleanup inside one sheet, use the AI built into your spreadsheet: Google Sheets’ AI function can categorize, summarize or tag rows, and Excel’s Flash Fill and Copilot handle reformatting and formulas. For weekly updates that pull numbers from other apps, use imports where they exist, and a person or an agent for apps that only show the numbers on screen.

How To Do It

These steps work with the tools you already have, whatever you use.

  1. Clean The Layout First

    One header row, one record per row, no merged cells, one date format. AI features and formulas both fail on messy layouts.

  2. Use The AI Function In Google Sheets

    With an eligible Workspace or Google AI plan, type =AI("Categorize as Travel, Meals or Supplies", A2), or use Insert › Function › AI, then click Generate and insert. Results can be regenerated but not undone, and up to 350 selected cells run at once.

  3. Use Excel’s Pattern Tools

    Flash Fill (Data › Flash Fill or Ctrl+E) learns a pattern from one example, like splitting full names. With a Microsoft 365 Copilot license, Copilot in Excel suggests formulas and highlights data from a plain request.

  4. Pull Data In Instead Of Pasting

    IMPORTRANGE brings in data from another Google Sheet; Excel’s Get Data imports files and other sources and refreshes in one click. Many apps export a CSV you can drop into the same tab each week.

  5. Freeze Results You’ve Checked

    AI formulas can change when regenerated. Once results look right, copy them and paste back as values only so the numbers stay put.

  6. Keep A Way Back

    Note who refreshed the sheet and when in a cell at the top, and use File › Version history in Sheets to roll back a bad update.

What To Watch Out For

  • Check AI categories on a sample. They sound confident even when wrong.
  • Don’t run customer personal details through AI features your business account doesn’t cover.
  • Thousands of AI formulas slow a sheet down. Run them on new rows only.

How Octopus Prime Does It

For weekly numbers that live inside other apps’ screens, an Octopus Prime agent collects them and updates your sheet, one source at a time.

  1. Show It The Sheet

    Connect Google Sheets or put the file in the project folder, and describe each column in a sentence.

  2. List The Sources

    “Every Monday: last week’s sales from Shopify, ad spend from Meta Ads, new leads from HubSpot. Add a row to the Weekly tab.”

  3. Let The Task Wake It

    A repeating Monday task wakes the agent, which opens each app with your login from the Vault and types in the figures.

  4. Flag Anything Odd

    Ask it to post in the project chat when a number is far off last week’s, so you check that one first.

Questions

Can ChatGPT update my Excel spreadsheet?

An AI chat can analyze an uploaded copy and hand back a new file. To change the live workbook, use the AI built into Excel or Sheets, or a tool that works in the file with your login.

What does the AI function in Google Sheets do?

It runs a prompt on the cells you reference, for example to categorize, summarize or rewrite text, and writes the answer into the cell. It needs an eligible Google plan.

How do I stop AI results from changing after the fact?

Copy the results and paste them back as values only.
