Claude Sheets is a beta spreadsheet inside Claude that builds a working sheet, with real formulas, from a plain-English prompt. In our test it produced a three-month freelance budget in under 30 seconds and every number checked out. It is a good first-draft tool, but it is not an Excel replacement yet: pivot tables, find and replace, and live data are missing.
This guide covers what Claude Sheets is, what we tested, how to check an AI-built spreadsheet before you trust it, and when to stay in Excel or Google Sheets.

What is Claude Sheets and who can use it?
Anthropic launched Claude Sheets in beta on 10 November 2026, alongside Claude Whiteboards and a generally available Claude Data. According to Anthropic’s announcement, Claude can generate spreadsheets with tabs, formulas, formatting and drop-downs, often from a single prompt such as a campaign tracker or a hiring budget.
Access depends on your plan. Anthropic’s artifacts help page lists Sheets as a beta template on Pro, Max, Ultra, Team and Enterprise plans. It is on by default for Team plans and off by default for Enterprise plans until an owner turns it on. Anthropic also says Claude Sheets counts toward your plan’s usage limits. We found it as a Sheets tile marked Beta in the Artifacts tab of a Pro account.
What happened when we asked Claude Sheets for a budget?
We ran one test on 13 November 2026, in the web app on a Claude Pro account. We opened a blank sheet, clicked Ask Claude, and sent this prompt:
Build a monthly freelance budget for 3 months (Jan, Feb, Mar). Columns: Month, Income, Rent, Software, Tax set-aside (20% of income, as a formula), Total expenses (formula), Net profit (formula). Add a totals row with SUM formulas. Use sample numbers.
The finished sheet appeared in under 30 seconds, named “Budget”, with a formatted header and a bold totals row.
Here is what we checked:
- Formulas are real. Tax set-aside in E2 is
=B2*0.2, total expenses in F2 is=C2+D2+E2, and the net profit total is=SUM(G2:G4). - The arithmetic is right. We recomputed every figure by hand. January’s tax set-aside is £840 (20% of £4,200), expenses are £1,910 and net profit is £2,290. The totals row matches too: £12,900 income, £5,815 expenses and £7,085 net profit.
- It picked pounds without being asked. Our prompt gave no currency. The sheet used £, so check the currency format on anything you send to others.
- The 20% rate is buried in each formula. Claude wrote
0.2straight into the tax formulas instead of using a labelled assumption cell. To change the rate you would edit three formulas. A better prompt would ask for assumptions in their own cells.
This was one prompt, one run and one account. A different prompt, plan or day may give different results, and we did not test import, export, sharing, mobile or large sheets.
How do you check a spreadsheet Claude builds for you?
Anthropic’s help page notes that formulas stay in the cells, so you can see how each number was calculated. Use that. A quick five-step check takes a few minutes:
- Click a result cell. Confirm it holds a formula, not a typed number.
- Follow the references. Make sure each formula points at the right row and column.
- Recompute one total by hand. Add one column on a calculator and compare.
- Look for hidden constants. A number like
0.2inside a formula is an assumption. Ask Claude to move it to a labelled cell. - Check units and currency. Confirm the format matches what your reader expects.
If you keep standing instructions for work like this, Claude Projects are a good place to store them, such as “always put assumptions in their own cells”.
What can’t Claude Sheets do yet?
Anthropic’s announcement says sheets have simple spreadsheet functionality for now, with more to come. The Get started with Claude Sheets page lists the current limits. We did not test these ourselves, so treat them as Anthropic’s documentation as of 13 November 2026:
- Size: up to 100,000 cells per sheet.
- Functions: 144 built in.
- Not available yet: pivot tables, protected ranges, find and replace, multi-column sort, filter views, multi-select drop-downs and PDF export.
- Excel features not supported: macros, VBA, Power Query, DAX and print layout.
- Live data: sheets cannot pull live data from connected apps.
- Mobile: basic read-only access. Editing is on web and desktop.
- Data controls: HIPAA, CMEK and zero data retention are not yet supported, so keep sensitive or regulated data out of beta sheets.
Claude Sheets, Claude for Excel or Google Sheets: which should you use?
Anthropic points people to export or to Claude for Excel when they need full Excel features. The table compares what each option is for, using Anthropic’s own pages.
| Option | Best for | Main limit |
|---|---|---|
| Claude Sheets (beta) | Building a first-draft tracker, budget or plan from a prompt, then editing it with Claude | Simple functionality, 100,000 cells, no pivot tables yet |
| Claude for Excel | Working inside Excel files you already have, including sorting, filtering and pivot table edits | Needs Excel and the add-in; macros and VBA operations are not supported |
| Claude for Google Workspace | Working in a Google Sheets file you already have, including formulas and pivot tables | Needs Google Workspace and the add-on, which is in beta |
A simple rule: start in Claude Sheets when you want a draft quickly and the file is small. Export to .xlsx or CSV, or move to Excel or Google Sheets, when you need pivot tables, macros or print layout.

Claude Sheets FAQ
Is Claude Sheets free?
Anthropic lists Sheets on paid plans (Pro, Max, Ultra, Team and Enterprise). We did not see it listed for free accounts. Check your own Artifacts tab.
Can I open a Claude Sheets file in Excel?
Anthropic says you can export a sheet to .xlsx or CSV. We did not test the export, so open the file and recheck your formulas after exporting.
Can I import my own spreadsheet?
Anthropic’s help page lists importing a CSV file, importing from Excel or Google Sheets, and pasting from either. The blank sheet we opened showed those import buttons. We did not test any of them, so check the result against your source file.
Is Claude Sheets safe for confidential data?
It is a beta product, and Anthropic says HIPAA, CMEK and zero data retention are not yet supported. Avoid regulated or highly sensitive data for now.
How we tested and what we checked
We tested on 13 November 2026 on a Claude Pro account in Chrome (UK), using the web app. We opened a blank sheet, sent one budget prompt through Ask Claude, then clicked into the result cells to check each formula and recomputed every figure by hand from what the sheet displayed. Product facts come from Anthropic’s announcement and help pages, checked on 13 November 2026. Anything marked as not tested comes from that documentation, not from our own use. Features, limits and plan access may change while the product is in beta.
