How to Connect Google Sheets to Claude and Build a Marketing Dashboard — Entirely with AI

You have marketing data scattered across Google Ads, Meta Ads, GA4, and half a dozen other platforms. You want a unified view — a dashboard your team can use to make decisions, not just export CSVs and copy-paste into pivot tables every Monday morning.

This guide shows you how to build that dashboard without a BI tool subscription, without a developer, and without SQL. The workflow is: get all your marketing data into Google Sheets in a clean, structured format, connect that sheet to Claude AI, and let Claude build the interactive dashboard for you.

By the end, you’ll have a working marketing dashboard generated by AI from your own live data — and you’ll understand exactly how to keep it updated week after week.

Why Claude + Google Sheets is the Marketer’s New Superpower

Google Sheets is where marketers already live. It’s flexible, shareable, and familiar. But it’s terrible at understanding data — VLOOKUP, QUERY, and nested IF formulas require expertise and break the moment someone renames a column.

Claude reads your data the way a senior analyst would. You describe what you want in plain English, Claude performs the aggregation, identifies trends, writes the narrative explanation, and generates the code for a fully interactive dashboard that runs in any browser. No formula knowledge required.

What makes this workflow uniquely powerful for marketers:

• Claude supports up to 200K token context windows — enough to process months of multi-channel marketing data in a single conversation.
• Claude Artifacts generates live, interactive HTML dashboards — rendered directly in the chat window and shareable with a single link.
• MCP (Model Context Protocol) allows Claude to read your live Sheets data without any manual export step.
• The entire dashboard is generated by AI — you write prompts, not code.

Step Zero: Get Your Marketing Data into Google Sheets — Structured and Ready for AI

Before Claude can analyze anything, your data needs to actually be in Google Sheets — and it needs to be structured correctly. This is the step most tutorials skip, and it’s the reason most AI-generated dashboards produce mediocre results.

Manually copying data from Meta Ads, Google Ads, and GA4 into a spreadsheet is error-prone and unsustainable. You need a pipeline that pulls that data automatically, keeps it up to date, and structures it in a way that makes Claude’s job easy.

Step-by-Step: Send Marketing Data to Google Sheets with Porter Metrics

Blending Multiple Marketing Sources: Where the Real Insights Live

Single-platform data tells a partial story. Your Google Ads dashboard shows clicks. Your Meta Ads dashboard shows reach. GA4 shows sessions. But none of them show you the full picture: what combination of channels actually drove revenue this quarter?

Porter Metrics lets you blend data from multiple marketing platforms into a single unified table in Google Sheets. When you pass that blended sheet to Claude, you unlock a completely different level of analysis — cross-channel attribution, spend efficiency comparisons, and full-funnel visibility that no single platform can provide on its own.

The 4 Methods to Connect Google Sheets to Claude

Once your marketing data is in Google Sheets (via Porter Metrics or manually), you have four ways to connect that sheet to Claude. The best choice depends on your technical level and what you want to achieve.

For the full dashboard generation workflow covered in this article, we recommend Method 2 (MCP + Claude Desktop). It’s the most capable, free, and doesn’t require programming skills beyond a one-time 30-minute setup.

Method 1: The Official Claude for Sheets Add-on

The simplest way to bring Claude into your spreadsheet is the official Claude for Sheets add-on, built by Anthropic and available in the Google Workspace Marketplace. It lets you call Claude directly from a cell using a formula — useful for cell-level tasks like summarizing ad copy, classifying campaigns, or generating variations.

How to Set It Up

1. Go to Google Workspace Marketplace and search for Claude for Sheets.
2. Click Install and accept the required permissions.
3. In your spreadsheet, go to Extensions → Add-ons → Manage add-ons.
4. Click the menu next to Claude for Sheets and check “Use in this document”.
5. Reload the sheet. After 5–10 seconds, the Claude for Sheets sidebar will appear.
6. Enter your Anthropic API key (get one at console.anthropic.com).

Basic Usage for Marketers

Once set up, use the =CLAUDE() formula to run AI analysis on any cell in your marketing data:

=CLAUDE("Classify this campaign objective as Awareness, Consideration, or Conversion: " & A2)

=CLAUDE("Suggest 3 improved ad headlines based on this current headline: " & B2)

=CLAUDE("What does this ROAS of " & C2 & " suggest about campaign profitability? Answer in one sentence.")

Fixing the Error 404: Model Deprecated Bug

1. In your spreadsheet, go to Extensions → Apps Script.
2. Delete any existing code and paste the following:

function CLAUDE_CUSTOM(prompt) {
  const API_KEY = "YOUR_ANTHROPIC_API_KEY";
  const url = "https://api.anthropic.com/v1/messages";

  const payload = {
    model: "claude-sonnet-4-6",
    max_tokens: 1024,
    messages: [{ role: "user", content: prompt }]
  };

  const options = {
    method: "post",
    contentType: "application/json",
    headers: {
      "x-api-key": API_KEY,
      "anthropic-version": "2023-06-01"
    },
    payload: JSON.stringify(payload)
  };

  const response = UrlFetchApp.fetch(url, options);
  const json = JSON.parse(response.getContentText());
  return json.content[0].text;
}

3. Click Save, then close the Apps Script editor.
4. Back in your sheet, use =CLAUDE_CUSTOM("Your prompt here") instead of =CLAUDE().

Method 2: Claude Desktop via MCP — The Most Powerful Setup

MCP stands for Model Context Protocol — Anthropic’s open standard for connecting AI assistants to external tools and data sources. With MCP configured, Claude Desktop can read your Google Sheets directly, analyze your live marketing data, and generate a complete interactive dashboard — all in a single conversation.

This is the method we recommend for building the full dashboard workflow described in this guide.

What You’ll Need

• Claude Desktop — latest version for macOS or Windows
• A Google account (personal Gmail or Google Workspace)
• A Google Cloud project (free to create at console.cloud.google.com)
• uv package manager installed on your machine

Step-by-Step Setup

{
  "mcpServers": {
    "google-sheets": {
      "command": "uvx",
      "args": [
        "mcp-google-sheets@latest",
        "--credentials-file",
        "/full/path/to/your/credentials.json"
      ]
    }
  }
}

Method 3: Claude Code + Composio (Developer Route)

For marketers with a technical background or a developer on the team, Claude Code paired with Composio as the MCP middleware offers the most flexible and scriptable setup. It supports full CRUD operations, multi-sheet workflows, and automated report generation that runs on a schedule without any manual intervention.

# Step 1: Install Claude Code
curl -fsSL https://claude.ai/install.sh | bash

# Step 2: Add the Google Sheets MCP via Composio
claude mcp add --transport http googlesheets-composio \
  "YOUR_COMPOSIO_MCP_URL" \
  --headers "X-API-Key:YOUR_COMPOSIO_API_KEY"

# Step 3: Restart Claude Code
exit
claude

# Step 4: Verify the server is registered
claude mcp list

After authentication, you can interact with your marketing spreadsheets in natural language:

• “Read the Porter Metrics export in the ‘Paid Media’ tab and calculate ROAS by channel for the last 30 days.”
• “Create a new sheet called ‘Weekly Summary’ and populate it with aggregated totals from the raw data tab.”
• “Compare this week’s spend vs. last week’s spend across all campaigns and flag anything that increased by more than 20%.”

Method 4: Automation with n8n or Albato

If your goal is to automate recurring marketing tasks — like sending a weekly AI summary of your Sheets data to Slack, or having Claude analyze new rows as they’re added by Porter Metrics — automation platforms like n8n or Albato are the right tool.

The workflow logic follows a simple pattern: New data added to Google Sheets by Porter Metrics → Claude AI analysis → Summary sent to Slack / Email.

Both n8n and Albato offer free tiers and pre-built templates for the Sheets + Claude integration. This method is best for automated reporting pipelines, not for building interactive dashboards from scratch.

The Full Pipeline: Porter Metrics + Google Sheets + Claude Dashboard

Now that your marketing data is in Google Sheets via Porter Metrics and Claude is connected via MCP, here is the complete dashboard generation workflow. This is the part that turns raw marketing data into a shareable, interactive visual report — without writing a single line of code.

Marketing Prompt Library — Copy and Paste into Claude

Use these prompts as starting points after Claude has read your Google Sheets data. Each one is tailored for a specific marketing use case. Paste them directly into Claude Desktop once your MCP connection is active.

Build an interactive HTML paid media dashboard from this data. Include: 4 KPI cards (Total Spend, Total Revenue, Overall ROAS, Total Conversions), a line chart of daily spend by platform over the selected period, a horizontal bar chart ranking campaigns by ROAS (highest to lowest), a scatter plot of Spend vs. Conversions by campaign, and a sortable data table with all campaigns. Flag any campaign where ROAS is below 1.5 in red. Add a platform filter at the top.

Create a cross-channel attribution dashboard HTML page from this blended data. Show: a stacked bar chart of revenue by channel over time, a comparison table of Spend / Revenue / ROAS / CAC for each platform, a line chart showing conversion trends by channel, and a budget allocation recommendation based on current ROAS. Highlight the channel with the best ROAS. Include a period selector (last 7 / 30 / 90 days).

Build an SEO performance dashboard from this data. Include: KPI cards for Total Impressions, Total Clicks, Average CTR, and Average Position. Show a line chart of impressions and clicks over time, a table of top 20 queries sorted by impressions with CTR and position, a chart comparing pages by click volume, and a highlight section showing queries with high impressions but CTR below 3% (biggest optimization opportunities). Clean, minimal design.

Generate a social media performance dashboard HTML file from this data. Show: CPM by platform (bar chart, lowest to highest), CTR comparison across platforms (horizontal bars), weekly reach trend by platform (line chart), engagement rate and cost-per-engagement table, and a top creatives section with the 5 highest-performing ad names by CTR. Use platform brand colors where possible. Add a date filter.

Build a campaign ROI and budget pacing dashboard. Include: a KPI summary row showing total budget used vs. remaining, total revenue, and blended ROAS. A bar chart showing budget pacing by campaign (% spent vs. % of period elapsed). A table of all campaigns with Budget, Spent, Remaining, Revenue, ROAS, and a "Pacing" status (Ahead / On Track / Behind). Flag campaigns that are overpacing or underpacing by more than 15% in orange. Add a "Recommended action" column where Claude suggests pausing, scaling, or adjusting each campaign.

Tips for Better Marketing Dashboards

• Let Porter Metrics handle data structure: The single biggest factor in dashboard quality is how clean and structured your input data is. Porter Metrics normalizes field names, date formats, and numeric values across platforms automatically — so you start with data Claude can actually work with, not a spreadsheet you have to clean first.
• Always include a “Platform” or “Source” column: When blending data from multiple sources, make sure your sheet has a column identifying which platform each row came from. This lets Claude group, filter, and compare channels cleanly in any chart or table it generates.
• Anchor the dashboard to a specific decision: Before writing your prompt, decide what decision this dashboard should support. Add that context explicitly: “This dashboard will be reviewed by our CMO on Monday to decide where to reallocate budget for Q2.” Claude will prioritize the most relevant metrics for that audience.
• Iterate, don’t start over: Claude maintains context across the conversation. After the first dashboard is generated, ask for specific changes: “Change the bar chart to horizontal.” / “Add a 7-day rolling average line to the trend chart.” / “Include a benchmark line for our target ROAS of 3.0.” Each iteration takes seconds, not hours.

Frequently Asked Questions

Start Building Your Marketing Dashboard

The combination of Porter Metrics, Google Sheets, and Claude eliminates the three biggest bottlenecks in marketing reporting: getting data out of platforms, structuring it for analysis, and turning it into something visual and shareable.

The workflow is clear: use Porter Metrics to pull your marketing data from 20+ sources into a clean, structured Google Sheet on autopilot. Connect that sheet to Claude via MCP. Describe the dashboard you need in plain English. In minutes, you have an interactive, shareable marketing report built by AI from your live data.

Start with a single channel — Meta Ads or Google Ads — run it through Porter Metrics into Sheets, and build your first Claude dashboard. Once you see how fast the iteration loop is, you’ll never go back to building charts manually.
