Claude Sheets, Whiteboards: Anthropic takes on Microsoft Office

On 10 November 2026, Anthropic began rolling out three new features in the Claude app: Claude Sheets, Claude Whiteboards and Claude Data. According to Frandroid, the announcement was made on the company's website and on Claude's official X account, which sums up the idea in one sentence: think a plan through on a board, build a tracker in a spreadsheet, tell a story with your data. Hipertextual, which relies on TechCrunch, places the launch in the context of Anthropic preparing an initial public offering, a framing that outlet presents as such and that the other two sources do not comment on.

What the new features contain

Claude Sheets lets people build a spreadsheet together with the AI, including tab management and calculation formulas, according to Frandroid and The Decoder. Per Hipertextual, users do not need to start from an empty file: they describe a budget or a campaign tracker in natural language, and Claude generates a sheet with tabs, formulas and drop-down menus. They can then ask for cell changes and for an explanation of each modification, so that the whole team knows what was done.

Claude Whiteboards takes the form of a shared whiteboard, designed to structure a meeting on the fly before the assistant produces a clean summary, writes Frandroid. Hipertextual adds that Claude can turn the content into a document or a presentation, and that the tool is meant to work with Claude Meetings. Claude Data, finally, is the former Dashboards module launched in October: it leaves beta, connects to tools such as Snowflake or Salesforce, and adds data stories, narrated videos and the sharing of up-to-date figures with colleagues.

The access conditions, according to Frandroid, are as follows:

• Sheets and Whiteboards are in beta, on the web, in the desktop app and on mobile, for paid plans starting with Pro ($20 per month before tax in the United States).
• On Team plans they are enabled by default; on Enterprise plans they stay off until an administrator turns them on.
• Claude Docs and Claude Slides, introduced in mid-September, were extended in October to all users, including the free plan.
• Claude Meetings is promised "soon", with no date.

The sources are not perfectly aligned on this last point. Hipertextual states that Claude Meetings will be available in beta for Team and Enterprise users, at first only with Google Meet, while Frandroid and The Decoder speak of an upcoming arrival with no timetable. Its availability should therefore be treated as unconfirmed.

Partners, meetings and security

Anthropic is also introducing "interactive connectors": partners such as Adobe or Atlassian can embed their applications directly in Claude, without switching tabs. The Decoder also names Salesforce and compares the mechanism to ChatGPT plugins, while Hipertextual mentions HubSpot. Claude's extension store claims more than 9,000 connectors and plugins, counting those built by the community, according to Frandroid. For Enterprise customers, The Decoder notes security controls: audit logs, isolated virtual machines and a compliance API.

Claude Meetings is described as an agent that joins video calls to take notes and update the team's documents. Hipertextual, citing TechCrunch, reports that it would always identify itself as a participant and would not join calls with outside guests without the administrator's authorisation.

An attack on Microsoft's home ground

Frandroid stresses the irony of the situation. Microsoft offers Claude models in Copilot for Word, Excel and PowerPoint, added Claude Opus 5 on 24 July, and on 9 March congratulated itself on having integrated the technology behind Claude Cowork into Microsoft 365 Copilot. Anthropic also already sells add-ins for Word, Excel, PowerPoint and Outlook, included from the Pro plan, and since 6 October has offered an extension for Google Docs, Sheets and Slides. With Sheets and Whiteboards, the company is no longer content to graft itself onto other people's suites.

The approach is the reverse of Microsoft's: the document is born in the conversation thread with the assistant, then exported if needed, in Word format for Docs, or as PowerPoint or PDF for Slides. On price, Frandroid says Microsoft 365 Copilot Business costs €18.20 before tax per month per employee on top of an existing Office licence, while Claude's Team plan starts at $20 before tax per seat on an annual subscription, with nothing to install but with no equivalent to Outlook, Teams or SharePoint. Also according to Frandroid, which cites CNBC, Microsoft's share price fell 3% on Tuesday.

Anthropic does not claim to dethrone Excel overnight. The company acknowledges that Claude Sheets is for now limited to the basic functions of a spreadsheet and points to an .xlsx or CSV export, or to its Claude for Excel module, when more is needed. To defend its approach, it highlights its own experience: its legal team says it went from three days to 24 hours to review marketing content, and the finance team at customer Advantage Solutions says it spends less than 30 minutes, against about 10 hours, preparing the presentations for each forecast cycle. These figures come from Anthropic and have not been independently verified.

What it changes for a company in Spain

For a Spanish small business or finance department, nothing in these announcements justifies leaving Office: Sheets is in beta and limited to basic functions. Testing is cheap on a simple case, such as a forecast budget or a campaign tracker, as long as the .xlsx export is kept as a safety net. Three points deserve a decision: the comparative cost (€18.20 before tax per employee for Copilot Business against $20 before tax per seat for Claude Team), activation by an administrator on Enterprise plans, and where data is processed, which the sources do not specify and which will need checking against the GDPR before any use on customer data.
