Your organisation has recently provided you access to Claude. Maybe it arrived via a company-wide rollout, a new seat in a Team plan, or IT quietly sent around a login. Either way, you've got a tab open and you're not quite sure what to do with it beyond "ask it things."

This guide focuses on essential aspects for day-to-day workplace use in 2026: connecting it with your CRM, converting it into a presentation, comprehending large datasets, and doing all this without exposing client data or wasting time on hallucinated statistics.

No fluff. Just what it does well, what it doesn't, and how to get started on the things most office users actually need.

What you're working with

Claude is a large language model made by Anthropic. In practical terms, it reads text (and files, and images) you give it, and responds. It doesn't browse the internet unless it says it is. It doesn't know what happened last week. It doesn't have access to your calendar or inbox unless you connect those tools.

What it's good at: understanding complex requests, processing large documents, writing with nuance, and handling structured tasks like "rewrite this email in a more formal tone" or "pull the key numbers from this 80-page report into a summary table."

As of mid-2026, Claude operates in four primary versions for workplace use:

• Claude.ai (browser or desktop app): where most users spend their time. Chat interface, file uploads, projects, tools.
• Claude for Microsoft 365: Excel and PowerPoint add-ins, available from Microsoft Marketplace. Works inside Office.
• Claude Desktop: the standalone app (Mac and Windows), with direct filesystem access and MCP connector support.
• API: for teams whose developers want to build Claude into custom tools or internal workflows.

Your company's IT or admin team chose a plan when they signed up. This matters because what you can do depends on it.

If your company provided access and you’re unsure of the plan you're on, check Settings > Account in Claude.ai.

Connecting Claude to HubSpot

HubSpot has a native connector for Claude that's worth setting up if your team uses it for CRM, marketing, or support. Anthropic and HubSpot built this together, and it lives directly inside Claude's chat interface, with no API key management required.

To connect:

1. Open Claude.ai and go to Settings > Connectors.
2. Click Browse Connectors and find HubSpot under the Web Connectors tab.
3. Click Add to your team, then Connect. You'll be sent to HubSpot's portal selector to choose your account.
4. In any new chat, enable HubSpot as a data source via the toolbar icon next to the message bar.

Once connected, you can ask Claude things like:

• "Find all contacts who opened the May newsletter but didn't click the CTA. Give me a table sorted by company size."
• "Summarise my open deals by pipeline stage and close date."
• "Create a new contact: [name, email, company] and log that we spoke on 15 May."
• "Show all support tickets assigned to me, priority order."

Claude can write records back to HubSpot: create contacts, update deal stages, log notes and tasks. This integration supports read and write capabilities, rather than being read-only.

Requirements: you need a paid Claude subscription (Pro, Max, Team, or Enterprise) and an active HubSpot user account. It doesn't work on the free Claude tier.

Building presentations and slide decks

Most people try Claude for slides the wrong way: they ask for bullet points and paste them into PowerPoint themselves. You can do better.

There are three solid approaches depending on what you need:

Claude Design (claude.ai/design)

Anthropic's newest tool, available to Pro plan subscribers and above. You describe the deck you want, Claude generates a fully formatted, clickable HTML slide deck in a canvas on the right side of your screen. It accepts uploads (Word docs, PDFs, spreadsheets) as source material. Export to PPTX, PDF, or standalone HTML when you're done.

The standout feature: if you paste in your company website URL or upload a brand doc, Claude Design infers your colour palette, fonts, and layout conventions before it generates anything. First-draft consistency is noticeably better than working from a blank prompt.

Realistic timeline: simple decks (10-15 slides, one data source) typically take two to four back-and-forth exchanges.

Claude for PowerPoint (Microsoft 365 add-in)

Install it from Microsoft AppSource (search "Claude for PowerPoint"), sign in with your Claude account, and Claude appears as a side panel inside PowerPoint.

You describe what you want, and Claude generates slides that conform to your existing template's fonts, colours, and layout masters, giving you brand consistency without extra effort. You can also highlight existing slides and ask Claude to rewrite, simplify, or expand specific sections.

Works well for: turning a research document into a formatted deck, rewriting dense text slides into cleaner bullet points, and generating speaker notes from slide content.

Using Artifacts (for quick or technical decks)

In any Claude.ai chat, ask Claude to build a "presentation as an artifact." It'll generate an HTML slide deck you can cycle through in the preview panel. Less polished than Claude Design, but faster and doesn't eat into your Design budget. Good for internal working decks where visual polish isn't the priority.

Working with PDFs and documents

Claude handles document work well. As of April 2026, it can both read and create PDF, Word, Excel, and PowerPoint files directly, without needing a third-party converter.

Reading and extracting from existing documents

Upload a PDF (or multiple) into any Claude chat. Useful patterns:

• "Extract all the financial figures from this contract and put them in a table."
• "I've uploaded three supplier quotes. Which is cheapest over a 12-month term including GST? Assume NZD pricing."
• "Summarise this 90-page annual report into five bullet points, then write a one-page executive summary."
• "Find every clause that mentions liability or indemnity in this agreement."

File limits: up to 30 MB per file, up to 20 files per chat session.

Creating documents from scratch

Type a request like "Create a formal quotation letter for a NZD $12,000 website project, 30-day payment terms, GST exclusive," and Claude produces a formatted .docx file you can download and open directly in Word or Google Docs. Same for PDFs and spreadsheets.

This is especially useful for first drafts of standard documents: proposals, meeting agendas, briefs, SOWs. Claude gets you 80% there in seconds.

Form completion

Upload a PDF form with fields, describe your details, and Claude fills it. The output is a completed document you can save or send. Works well on standard business forms; less reliable with complex conditional logic.

Analysing and reporting on large data

This is one of Claude's strongest real-world use cases right now, especially with the large context window on newer plans.

Uploading spreadsheets and CSVs

Drop a CSV or Excel file directly into the chat. Claude can handle files up to 30 MB and reads multi-sheet workbooks. On Enterprise plans (1M token context window), you can upload multiple large files in one session.

Claude for Excel (the Microsoft 365 add-in, released to all Pro users in January 2026) lets you work directly inside Excel without switching tabs. Open your spreadsheet, activate the Claude panel, and describe what you want:

• "Identify rows where the invoice amount is more than 20% higher than the quoted amount."
• "Calculate average customer lifetime value by acquisition channel."
• "Flag all entries where the GST rate is missing or zero."

Claude can write Excel formulas, pivot table instructions, and conditional formatting rules back to you in plain English.

Large report analysis

Paste a 100-page market report, an annual return, or a long meeting transcript, and Claude can summarise it, extract specific data, identify discrepancies, or reformat it as needed.

The practical limit is the context window: on Pro and Max plans, you get 200,000 tokens (roughly 150,000 words). On Enterprise, it's 1 million tokens. Most business documents fit comfortably.

Producing reports automatically

Claude can take raw data and produce formatted, narrative reports:

"Here's our Q1 sales CSV. Write an executive summary (3-4 paragraphs), a bullet-point highlights section for the board pack, and a table showing month-over-month change for the top five products by revenue."

The output is copy-paste-ready. You won't get a live data visualisation natively in the chat, but you'll get structured, accurate narrative and tables based on the numbers you gave it.

Privacy and data: what you need to know before you paste anything

This is the most important section for workplace use, and the one most people skip.

What happens to what you type

Practical rules for everyday use

Don't paste real client data into a Free or Pro account. This includes customer names, email addresses, financial records, health information, or anything your clients would expect to stay private.

Don't paste passwords, API keys, or internal credentials. Claude doesn't need them for most tasks.

Anonymise before uploading where possible. Replace real names with "Customer A, Customer B" before uploading a spreadsheet of customer transactions. Claude works just as well on anonymised data.

Check your organisation's AI policy first. Many companies now have a formal AI acceptable-use policy. If yours doesn't, treat Claude as a non-NDA'd external contractor: share what you would share with a capable freelancer, not what lives in your ERP or client database.

Enterprise features worth asking IT about

If your organisation handles sensitive information, confirm these are enabled on your plan:

• SAML SSO: login managed through your company identity provider (Microsoft, Okta, etc.)
• Domain capture: ensures all company emails automatically fall under the managed account
• Spend controls: stops individual users from spinning up unexpected API usage
• BYOK (Bring Your Own Key): rolling out mid-2026, lets your company manage its own encryption keys

What Claude gets wrong (and how to catch it)

Claude is not infallible. Knowing the failure modes saves you embarrassment.

Getting started: five things to try in your first week

If you've made it this far and want somewhere to start, try these:

1. Summarise a long document. Upload a PDF (a contract, a report, meeting notes) and ask: "Summarise the key points in plain English, then flag anything that needs a decision or action."

2. Draft an email you've been putting off. Describe the situation and your desired outcome: "I need to push back on a client's request to extend our project without additional budget. I want to be firm but not damage the relationship. Here are the relevant emails: [paste them]."

3. Connect HubSpot and ask one question. Once connected, ask Claude to pull the last 30 days of new contacts and summarise acquisition sources. Compare it to what you'd normally build in HubSpot's reporting view.

4. Upload a spreadsheet and ask for insights. Paste or upload last month's sales data, a budget vs actual comparison, or a staff roster. Ask: "What's the most important pattern in this data that I should be paying attention to?"

5. Build a deck from a doc. Take a report or briefing document, upload it to Claude Design (or the PowerPoint add-in), and ask it to turn it into a 10-slide presentation. This method is quicker than starting with a blank slide in PowerPoint.

The realistic verdict

Claude is a genuinely useful tool for the kinds of tasks most office workers deal with daily: processing documents, drafting communications, pulling structure from messy data, and building presentation material. The HubSpot connector and the Microsoft 365 add-ins make the integration into existing workflows more practical than it was 12 months ago.

The limits are real. It's not a replacement for a domain expert, a live data feed, or a tool with actual access to your internal systems. It hallucinates. It doesn't know what happened last month. It's not appropriate for processing sensitive client data unless you're on an Enterprise plan with proper controls in place.

For NZ teams: Pro at USD $20/month is NZD $33 at current exchange rates. Team Premium seats are NZD 165−206/seat. The value case stacks up if you're replacing a few hours of manual work per week. If you're on a company-managed plan, the licensing decision isn't yours anyway.

Start with the five tasks above. Most people find the right use cases for their own work within a few days of actually using it.
