Claude Cowork's New Features: Connectors, Plugins & Excel Integration

Claude Cowork just received its biggest update yet. Anthropic announced a wave of new connectors, pre-built plugins for specific departments, and — the feature that has everyone talking — full Excel and PowerPoint integration. These are not incremental improvements. They fundamentally change what Claude can do inside a business workflow.

Until now, Claude Cowork was exceptional at working with text: writing, summarising, analysing, and drafting. But it lived in its own window. You would copy data from a spreadsheet, paste it into Claude, get a response, then copy that response back into another tool. It worked, but it was manual. That friction has now been removed across a wide range of business tools.

This update matters because it moves Claude from being a powerful writing assistant to being a genuine workflow engine — one that connects directly to the tools your team already uses, reads your data where it lives, and produces output in the formats you actually need. Here is everything that changed and what it means for your business.

New Connectors: Claude Now Talks to Your Tools

The headline change is that Claude Cowork can now connect directly to a growing list of business tools. Instead of copying and pasting information between applications, Claude reads from and writes to these tools natively. This is a fundamental shift in how AI fits into day-to-day work.

Google Workspace

Claude now integrates with Google Docs, Sheets, Slides, and Gmail. This means Claude can read a Google Sheet full of sales data, draft a summary in Google Docs, build a presentation in Slides, and compose follow-up emails in Gmail — all within a single conversation. For the millions of businesses that run on Google Workspace, this eliminates the constant tab-switching and copy-pasting that slows down even simple tasks. You can ask Claude to pull last month's revenue figures from a shared Sheet, identify the key trends, and draft an update email to stakeholders — and it does all of that without you leaving the Claude interface.

Business Tools

Docusign, Apollo, Clay, Outreach, Similarweb, WordPress, and Harvey are all now available as connectors. Each one opens up a specific category of work. Docusign integration means Claude can help prepare, review, and manage contracts and signature workflows. Apollo and Clay connect Claude to your prospecting and lead enrichment data — so Claude can research a prospect, draft a personalised outreach sequence, and push it directly to your CRM. Outreach integration takes this further by letting Claude manage email sequences and follow-up cadences. Similarweb gives Claude access to website traffic and competitive intelligence data, so market research that used to take an afternoon can happen in a conversation. WordPress integration means Claude can draft, format, and publish blog posts and page content directly. And Harvey — the legal AI platform — connects Claude to legal research and document analysis workflows for law firms and legal teams.

Financial Data

MSCI and FactSet connectors bring institutional-grade financial data directly into Claude. For investment professionals, analysts, and finance teams, this is significant. Claude can now pull ESG ratings from MSCI, access company fundamentals from FactSet, and use that data in analysis — all through conversation. Instead of logging into separate terminals, running queries, exporting CSVs, and then trying to make sense of it all, you can ask Claude to compare the ESG performance of five companies in your portfolio and get a structured analysis in seconds.

Slack Plugins

Anthropic also announced Slack plugins from Salesforce, LSEG (London Stock Exchange Group), S&P Global, Common Room, and Tribe AI. These bring Claude's capabilities directly into Slack — where most teams already spend their day. The Salesforce plugin lets teams query CRM data, update records, and generate reports without leaving Slack. LSEG and S&P Global plugins give financial teams instant access to market data and research within their messaging environment. Common Room connects community and customer engagement data, and Tribe AI brings specialist AI consulting capabilities into team conversations.

The practical impact of all these connectors is simple: less context-switching, less copy-pasting, and more end-to-end workflows. The tasks that used to require opening five tabs, exporting three files, and spending forty minutes stitching information together can now happen in a single Claude conversation.

Pre-Built Plugins by Department

Alongside the new connectors, Anthropic released a library of pre-built plugins designed for specific departments and functions. This is a smart move that addresses one of the most common barriers to AI adoption: not knowing where to start.

Previously, getting Claude to work well for a specific use case meant crafting detailed prompts, building project structures, and iterating until the output matched your needs. That process works — and Claudable's course teaches it well — but it takes time. Pre-built plugins give teams a working starting point that they can customise, rather than building from a blank canvas.

HR teams get plugins for drafting job descriptions, screening candidate responses, generating onboarding documentation, and creating policy documents. These are tasks that HR professionals do repeatedly, and having a pre-configured Claude workflow for each one saves hours per week.

Design teams get plugins for generating creative briefs, writing design system documentation, creating user research summaries, and drafting project specifications. Claude does not design visuals, but it handles the significant volume of written work that surrounds every design project.

Engineering teams get plugins for writing technical documentation, generating code review summaries, creating sprint retrospective reports, and drafting technical specifications. These are the tasks that engineers consistently deprioritise because they take time away from building — and now Claude handles them.

Operations teams get plugins for process documentation, vendor comparison reports, workflow analysis, and standard operating procedure creation. For ops teams that spend significant time documenting and optimising how a business runs, these plugins are immediately useful.

Financial analysis, investment banking, equity research, private equity, and wealth management each get dedicated plugin sets. Financial analysis plugins handle earnings summaries, ratio calculations, and trend analysis. Investment banking plugins support deal memos, pitch book content, and comparable company analysis. Equity research plugins generate company profiles, sector overviews, and earnings call summaries. Private equity plugins handle portfolio company reporting and due diligence documentation. Wealth management plugins create client portfolio reviews, market commentary, and investment recommendation summaries.

The key advantage here is speed to value. Instead of spending a week figuring out how to prompt Claude for your specific function, you install a plugin, connect your data sources, and start producing output immediately. You can then refine and customise the plugins over time as you learn what works best for your team.

Excel + PowerPoint: The Game Changer

This is the update that will get the most attention — and rightly so. Claude Cowork can now work across Excel and PowerPoint end-to-end. It is currently in research preview and available on all paid plans, for both Mac and Windows.

Here is what that means in practice: you can give Claude an Excel spreadsheet — a sales report, a financial model, a dataset of any kind — and ask it to analyse the data, identify key trends and insights, and then build a PowerPoint presentation based on that analysis. Claude reads the spreadsheet, runs the analysis, and produces a formatted slide deck. The entire workflow happens in one conversation.

Think about how that process works today. You open Excel, spend thirty minutes examining the data, build some pivot tables, create a few charts, copy those charts into PowerPoint, write slide titles and bullet points, format everything, and maybe share it for review. On a good day, that takes an hour. On a bad day — with a complex dataset or a high-stakes presentation — it takes most of an afternoon.

With Claude's new integration, that workflow compresses into minutes. You upload the spreadsheet, describe what you need, and Claude handles the rest. It identifies the most important data points, structures the narrative, creates appropriate visualisations, and produces a presentation that is ready to review and refine.

A real example: imagine you have a quarterly sales report in Excel with revenue by region, product line performance, and year-over-year comparisons. You need to turn that into a board presentation by Friday. Instead of spending three hours building slides, you ask Claude to do it.

Claude analyses the spreadsheet, identifies the patterns, and builds the presentation. You review it, make any adjustments, and you are done. What used to take three hours takes fifteen minutes — and the quality is often better because Claude does not rush or overlook data points when it is tired at the end of a long day.

This feature is available on all paid Claude Cowork plans, which means it is not locked behind an enterprise tier. Individual professionals on the Pro plan can use it just as effectively as large teams. That is a significant decision by Anthropic and one that levels the playing field for smaller businesses.

What This Means for Your Business

These updates shift Claude Cowork from a tool you use alongside your work to a tool that does your work — or at least the repetitive, time-consuming parts of it. The practical implications are significant and worth thinking through clearly.

Tasks that used to take hours now take minutes. This is not marketing language. Building a presentation from spreadsheet data genuinely drops from a two-to-three-hour task to a fifteen-minute review. Drafting a client email sequence from CRM data goes from an afternoon to a conversation. Producing a financial analysis from FactSet data that would take a junior analyst half a day can now happen in a few prompts. The time savings are real and they compound across every person on your team.

The gap between AI-ready and AI-native teams is widening. A year ago, the difference between a team using AI and a team not using it was modest — maybe an hour or two per week. With these integrations, the gap is becoming a chasm. Teams that adopt these workflows will operate at a fundamentally different speed. They will produce more output, respond to clients faster, and make better-informed decisions because the cost of analysis has dropped to near zero. Teams that are still copying and pasting between tabs will fall further behind every month.

No technical skills are required. This is the part that matters most for small and medium businesses. Every connector, every plugin, every integration works through natural conversation. You do not need to write code, configure APIs, or hire a developer. If you can describe what you need in plain English, you can use every feature announced today. The barrier to entry is not technical ability — it is awareness. Knowing these features exist and understanding how to use them is the only prerequisite.

The ROI calculation just got much simpler. When Claude could only work with text in its own window, the value case required some imagination. Now, with direct connections to CRM, email, spreadsheets, presentations, financial data, and Slack, the value is obvious and immediate. Every connector you activate saves time on specific, measurable tasks that your team does every week.
