AI agents for Google Sheets
A Monmo agent works in Google Sheets the way an analyst would. It builds budgets and trackers, cleans messy exports, writes and explains formulas, charts the results and reports on the numbers each week. It uses your own Google account, shows its working in formulas you can trace, and asks before it changes a cell in a sheet you already have.

What agents do in Google Sheets
Build a twelve-month budget
Give it last year's actuals and your plans. It builds a month-by-month budget with revenue, costs and cash, three scenarios side by side, and an assumptions tab that every figure traces back to.
AskBuild next year's budget from last year's actuals, with best, expected and worst cases, and tell me when we break even.
Clean a messy export
It removes duplicate rows, fixes dates and currencies typed three different ways, splits names from email addresses, and reports what it changed and which rows it could not resolve. It works on a copy unless you say otherwise.
AskClean the Orders export: remove duplicates, fix the date column and flag rows with no email address.
Write the formula and explain it
Describe the result you want and it writes the formula, tests it on your rows and explains each part in plain words. It can also find out why an existing formula returns an error.
AskThe margin column shows an error in some rows. Find the cause, fix the formula and explain what went wrong.
Keep a tracker up to date
An order log, a hiring pipeline or a content calendar: the agent gathers the day's new entries from email, forms or other apps, prepares the rows and status changes, and asks once before it writes the batch.
AskEach evening at 6, add today's new orders to the Orders tracker and mark the ones that shipped.
Turn data into charts
It picks the chart that fits the question, a line for a trend or bars for a comparison, labels the axes and the units, and puts the charts on a summary tab or into Google Slides.
AskChart monthly revenue by channel for this year and put the three charts on a Summary tab.
Send the weekly numbers
Every Monday at 9 it reads the sheet, compares this week with last and writes five lines on what changed and why. Each figure names the tab and the cell it came from.
AskEvery Monday at 9, send me a five-line summary of the Sales sheet: this week against last.
Compare two lists
Give it two tabs or two files, such as a payout export and your invoice list. It matches the rows and lists what appears in one and not the other, with the difference in each amount.
AskCompare the Stripe payout export with the Invoices tab and list anything that does not match.
Answer a question from the data
Ask which product had the best margin, or which customers have not ordered in 90 days. It builds the pivot table or the filter, shows how it got there and gives you the answer.
AskWhich five customers ordered most in the third quarter, and who has not ordered since June?
How it connects
- 1You sign in to Google once with your own account. The agent reads the spreadsheets you can read; it has no wider view of your organisation's data.
- 2Spreadsheets are open only to the agents you name. A finance or operations agent lives in them; a writing agent may never need one.
- 3Reading a sheet and working out an answer need no approval. Creating a spreadsheet in your account, or changing cells, tabs or formulas in an existing one, asks first, and one card can cover a batch of rows.

Questions people ask
Can an AI agent build a budget in Google Sheets?
Yes, with formulas you can follow. Give a Monmo agent last year's figures and your plans for the year, and it builds a monthly budget with scenarios and a summary. Every total traces back to an assumptions tab, so you can change a growth rate or a price and watch the result update. The decisions in the budget stay yours.
Can an AI agent clean up and analyse my spreadsheet?
A Monmo agent can remove duplicates, standardise dates and currencies, fill gaps from other columns and flag rows it cannot resolve, then answer questions with pivot tables and charts. It reports what it changed, row by row. By default it works on a copy, so your original data stays as it was.
Will an AI agent overwrite the data in my sheet?
Not without asking. Changing cells, deleting rows or rewriting formulas in a sheet you already have shows a card first, with the range and what will change. You can ask it to work on a copy instead. Reading the sheet and calculating an answer change nothing, so they need no approval.
Can an AI agent work with Excel and CSV files as well as Google Sheets?
Yes, the agent handles all three. It can open an Excel or CSV file on its own computer, work on it there and hand the result back as a file in the Library, or bring the data into Google Sheets once you allow it. In Google Sheets it works through the connection or, for something the connection cannot do, in the sheet itself in its own browser.
