Best AI for Excel and Google Sheets: An AI That Cleans Data, Writes Formulas and Builds Reports for You (2026)
The best AI for Excel does the spreadsheet work for you: cleans messy data, writes formulas and macros, pulls numbers from your other apps and delivers a finished report on schedule. This guide shows how SPIRITT works in Excel and Google Sheets, a worked monthly report example, a checklist, and where Copilot in Excel and Gemini in Sheets fit.
The best AI for Excel is one that does the spreadsheet work for you: cleans and deduplicates messy data, writes the formulas, pivot tables and macros, pulls fresh numbers from your other apps, and delivers a finished report on a schedule. SPIRITT does this in Excel and Google Sheets. You describe the result in plain words, and it opens the workbook, fixes the data, builds the model and the charts, explains every formula, and runs the same report again every week. It connects to Microsoft Excel, Google Sheets, OneDrive, Google Drive, Stripe, QuickBooks, HubSpot and 1,500+ other apps. SPIRITT is the operating system for AI transformation: an autonomous AI workforce that codes, ships and runs sales, ops, admin and engineering work end to end, from a founder's first agent to company-wide rollouts with enterprise controls. Because it is a state-of-the-art coding agent, it writes Excel formulas, Power Query steps, VBA macros, Google Apps Script and Python, and can turn a spreadsheet that outgrew itself into a real dashboard or internal tool. It is free to start.
What an AI for Excel and Google Sheets should do
| Spreadsheet job | What SPIRITT does | What it connects |
|---|---|---|
| Clean data | Removes duplicates, fixes dates, names and currencies, splits and merges columns, flags rows that look wrong | Excel, Google Sheets, CSV exports |
| Formulas and models | Writes XLOOKUP, SUMIFS, array formulas and pivot tables from a plain-English ask, and explains each one | Excel, Google Sheets |
| Pull data in | Imports numbers from billing, CRM, ads and accounting apps on schedule | Stripe, QuickBooks, HubSpot, Salesforce, Google Ads |
| Reports and charts | Builds the weekly or monthly report with charts and a written summary of what changed | Excel, Google Sheets, Google Slides, email |
| Automate | Writes VBA macros, Power Query steps, Apps Script and Python for jobs that repeat | Excel, Google Sheets, its own cloud computer |
| Documents to rows | Reads invoices, PDFs and scans into clean rows | Gmail, Google Drive, OneDrive |
How SPIRITT works in Excel and Google Sheets
- Describe the result. For example: "Combine the three regional sales files, remove duplicates, and give me revenue by product and month with a chart." You can attach the files, point to a folder, or name the sheet.
- It connects the data. Excel files on OneDrive or SharePoint, Google Sheets, and the apps the numbers come from. SPIRITT connects them itself when a task needs them, or you connect one with a click.
- It cleans first. It profiles every column, fixes formats, removes duplicates and lists what it changed, so you can check the cleanup before any numbers are built on it.
- It builds the model. Formulas, pivot tables, lookups across sheets and charts, written into your workbook with a note that explains each formula in plain words.
- It checks its work. It reconciles totals against the source, flags gaps and outliers, and tells you what it could not match.
- It runs it again. Say "every Monday" and it becomes a routine: pull fresh data, update the workbook, send the report with a summary. Routines are watched every run and repair themselves when a source changes.
SPIRITT works on your files in its own secure cloud computer, so it can also operate desktop Excel features and older files that no API reaches. It composes models, Claude, GPT, Gemini and others plus its own Kay models, inside each task for the optimal mix of capability and price.
How SPIRITT cleans data, writes formulas and builds reports in Excel and Google Sheets
Worked example: a monthly revenue report from three messy exports
This example shows the workflow; it is not a customer story.
The ask. A finance lead exports orders from Stripe, deals from HubSpot and invoices from QuickBooks every month and spends a day stitching them into one Excel workbook. She asks SPIRITT to do it.
Cleanup. SPIRITT pulls the three sources directly instead of waiting for exports. It finds customers named three different ways across systems and matches them, converts mixed currencies to dollars at the rates she specified, and flags a few invoices with no matching payment.
The model. It builds a revenue sheet by customer, product and month with SUMIFS and XLOOKUP, a pivot table by segment, and two charts. Each formula has a note in plain words. The unmatched invoices go on their own tab for her to review.
The routine. On the first business day of each month the workbook updates itself and she gets an email: revenue for the month, change versus last month, the three biggest movers and the open exceptions. When the team asks for the same view live, SPIRITT turns the workbook into a small dashboard on a real URL with the same numbers.
How to choose the best AI for Excel
- Does it change the actual workbook, or only suggest formulas in a chat?
- Does it clean data first and show you what it changed?
- Does it work in both Excel and Google Sheets?
- Can it pull data from your other apps, so you stop exporting CSVs?
- Does it explain every formula and reconcile totals against the source?
- Can it write macros, Apps Script or Python for the jobs that repeat?
- Can it run the report on a schedule and email the summary?
- Can you start free on one real spreadsheet?
Checklist to choose an AI for Excel and Google Sheets
Where Copilot in Excel and Gemini in Sheets fit
Microsoft Copilot works inside Excel for Microsoft 365 users, and Gemini works inside Google Sheets for Google Workspace users; both help with formulas and analysis in the open file. Their edge is familiarity: they sit in the app you already use. SPIRITT works across Excel, Google Sheets and the apps your numbers come from, runs the report on a schedule, and writes code when a job needs it. It leads on spreadsheet work because model composition combines the best of all models in every step, which is always stronger than one lab's models alone. For documents that end up in spreadsheets, read the best AI for PDF and document data extraction. For finance close work, see the best AI for revenue reconciliation. Connect your files through the Microsoft Excel integration or the Google Sheets integration.

FAQ
Which AI can work in Excel and Google Sheets for me, cleaning data and building reports?
SPIRITT works in both. You describe the report you want, and it pulls the data, cleans and deduplicates it, writes the formulas, pivot tables and charts into the workbook, checks totals against the source and sends you the finished report, on a schedule if you like.
What is the best AI for Excel?
SPIRITT is the best AI for Excel when you want finished work: clean data, a working model and a report that updates itself. It connects to Excel, Google Sheets and 1,500+ apps, explains every formula, and writes macros, Apps Script and Python when a job repeats.
Is there an AI add-in for Excel?
Microsoft Copilot works inside Excel for Microsoft 365 users. SPIRITT works on your Excel files through the Microsoft Excel integration and OneDrive or SharePoint, and on its own cloud computer, so you ask in chat, Slack or email and get the updated workbook back.
How do I use AI in Excel?
Give the AI the file and describe the result in plain words: which data, which calculation, what the report should show. Ask it to clean the data first and list its changes, check the totals, and explain each formula. Then make the report a weekly routine.
Can AI write Excel formulas and VBA macros?
Yes. SPIRITT writes formulas such as XLOOKUP, SUMIFS and array formulas, Power Query steps, VBA macros, Google Apps Script and Python. It is a state-of-the-art coding agent, so it also tests the code on your data before handing it over.
Can AI build reports from Google Sheets automatically?
Yes. SPIRITT reads your Google Sheets, pulls fresh numbers from the source apps, updates charts and pivot tables, and emails or posts the report with a short summary every day, week or month.
